Description

The present invention relates to a mechanical door or window lock a wireless security system with electrically at least one in a corresponding locking opening movable locking member and with a receiver, in particular a UHF receiver for wirelessly receiving control signals Control unit and an object security system with such mechanical door or window lock.

DE-G 94 13 062.0 is a mechanical door or window lock known, in which the bolt through a network connection and / or battery with a powered electric motor can be moved. Of the Electric motor is only switched on with a radio remote control and then moves the bolt via a control disc until one in the Control disc located recess arrived at a spring contact is that switches off the electric motor again. Press next time the remote control moves the electric motor in a similar way Control disc, the bolt then in the opposite direction is moved. This creates the difficulty that the user cannot recognize the current position of the bolt and not exactly knows whether the latch has just been retracted or extended. Only a tedious one Verification of the relevant door or window provided Clarity. An alarm function is not provided. Besides, can an unauthorized person who has an identical remote control Pull back the bolt just like the rightful owner. Of the Burglary protection is therefore very limited.

Proceeding from this, the present invention is based on the object to create a door or window lock for an object security system, which is a stable mechanical protection with a comfortable electronic Operability and combined with a reliable alarm system and yet not or only with difficulty to be overcome by unauthorized persons or is to be switched off.

As a technical solution to this problem, the invention proposes the above-mentioned door or window locking by one Position sensor for detecting the current position of the locking member and to send a corresponding information signal, a state sensor for detecting the closed state of the door or Window and for sending a corresponding information signal and / or alarm signals, an electronic evaluation unit for evaluation the control signals received by the control unit, and that of the position sensor and / or the status sensor received information signals and to control the locking member accordingly, and a transmitter, in particular a UHF transmitter, for wireless Sending the information signals and / or the alarm signal to the Control unit and / or an alarm output unit, in particular a siren, to further develop a telephone dialer and / or alarm lighting.

A door or window lock designed according to this technical teaching has the advantage that in addition to solid mechanical protection thanks to the two locking bolts with a diameter of 10 mm a reliable alarm system is also provided, whereby the entire system is easy to operate. By the user receives the various sensors via the control unit Information whether the door / window is closed or open, whether the Locking bolts are retracted or extended and whether the alarm system is switched on. In addition, the put on alert Condition sensor an alarm signal as soon as the door / window is unauthorized is opened.

The evaluation unit also evaluates the received signals and ignores all signals that have an incorrect code number. This is an essential protection against unauthorized operation of the door or Window lock reached.

To prevent unauthorized reading of the respective code number, in a preferred embodiment, a device for connecting and Decryption of data is provided so that the security standard of Door or window lock is further increased.

For a professional burglar, there is the option of the UHF transmitter emitted alarm signal by an interference signal of the same frequency to interfere at least partially, so that of the door or window lock The alarm sent is not on the siren or the telephone dialer arrives and the burglar can enter the property undisturbed can. To rule out this is in a preferred embodiment a second transmitter, an ultrasonic transmitter is provided. The ultrasound signal cannot be influenced by an interference signal. This ultrasound signal is in a preferred object security system by an ultrasound receiver recorded, which then sends the alarm signal via the in-house Telephone or power cable network to the desired alarm device. There the ultrasonic signal is disturbed by any obstacles, the Ultrasonic receiver in visual contact with the door or window lock to be appropriate. The use of the in-house cable network enables the cost-effective transmission of the alarm signal without one in the house A variety of ultrasonic transmitters and receivers can be built have to.

In another preferred embodiment, the door or window lock powered exclusively by a 9 volt battery. This has the advantage that the property security system in inexpensive existing buildings can be retrofitted because of the expensive and elaborate laying of power cables can be dispensed with. Another Advantage is that the components are not through by unauthorized persons Interruption of the general power supply can be deactivated can.

So that the battery has a lifespan of 1 to 2 years, they are UHF receivers clocked and only switch every 5 seconds for 100 Milliseconds on reception.

In another preferred embodiment, the locking member a hollow cylindrical guide element in which one of one Electric motor driven spindle engages, being on the guide element at least one locking bolt for insertion into the Locking opening is attached. This construction is extreme space-saving, among other things because there is no complex gear can be, and still allows a stable locking member with two 10 mm thick locking bolts, as otherwise only from the Safe building is known.

The door or window lock according to the invention has due to the compact design about the size of a cigarette box and can retrofitted to existing doors or windows in a simple manner because the width of the lock is smaller than most Window frames. In addition, the property security system according to the invention offers still an extremely stable mechanical lock, like she is known from the vault, and a reliable alarm system a simultaneously high security standard, so that the property security system cannot be overcome by burglars unnoticed.

As a further technical solution to the above problem according to the invention an object security system according to claim 12 suggested.

A property security system designed according to this technical teaching has the advantage that a central unit is completely dispensed with can, because every single component contains those for communication necessary technology so that in an emergency the locking unit alarm triggering signal directly to one or more alarm units sends, and that these alarm signals from the respective alarm unit are received accordingly and trigger the alarm. Thus creates the object security system according to the invention has increased reliability and thus increased security.

Another advantage is that through direct communication shorter between the locking unit and the alarm unit Communication channels are realized so that the alarm is much shorter Time can be triggered.

To further increase the security of the property security system, in a preferred embodiment, a device for connecting and Decryption of data is provided so that unauthorized reading of the Signals, especially the respective code number is difficult.

In another preferred embodiment, the evaluation unit comprises a tutorial, which during the commissioning of the respective Unit assigns this an individual code number, which will henceforth be used as an address serves. As soon as a unit receives a radio signal, it is heard in the radio signal

Referring to the drawing, there is one in the various figures Object security system according to the invention shown, in which the Communication between the individual components takes place wirelessly. At this object security system according to the invention is a user-friendly, processor-controlled system with which one can the current state (open or closed) of the door or of the window with which you can also find the correct one Locking the door or window ensures and with which to third notifies of an unauthorized opening of the door or window or is informed. Even if in this patent application only of Door or window is talked about, so it goes without saying that with it Roller shutters, garage doors, garden gates, cupboard or safe doors or others Objects to be secured, including cars, are meant.

In Figure 1, the object security system according to the invention is schematic shown. The property security system includes a permanently installed one Control unit 10 and a mobile hand control unit 12. The mobile hand control unit 12 is so small and compact that it can be used at any time can be taken out of the house and thus acts as a key. Both with the control unit 10 and with the manual control unit 12 the other components can not only be activated or deactivated but a condition check can also be done to determine whether the door or window in question is just closed, open or possibly broken. Next to the control unit 10 and the hand control unit 12 includes the invention Property security system also a mountable on an existing door Door lock 14, an attachable to an existing window frame Window lock 16 and a safe lock that can be installed in a safe door 18. A glass break detector can optionally be attached to the window lock 16 be connected. The glass break detector can be connected to the Glass break sensor 20 or one mounted in the window lock 16 integrated glass break microphone. Furthermore, the object security system according to the invention a motion detector 22, a gas or smoke detector 24 and a temperature detector 26. Zur Output of the alarm includes the object security system according to the invention a siren 28, the police, a security guard or the homeowner dialing telephone dialer 30 and an alarm light 32. Furthermore the security system according to the invention still has one here Emergency release, not shown. It is understood that the mentioned Components can also be present several times as required. In the embodiment of the invention described below Property security system can have up to sixty such components operated simultaneously. The individual components (this includes the control units) communicate wirelessly with each other. It is in contrast to known property security systems that the individual components directly, i.e. without switching on the control unit, can communicate with each other. The latter is indicated by the arrows in Figure 1 indicated.

To ensure communication between the components, is essentially the same in each of the above components Integrated communication element 34, which is schematic in Figure 2 is shown. This communication element 34 comprises a UHF receiver 36, a UHF transmitter 38 and an electronic evaluation unit 40. This electronic evaluation unit includes, among other things a device with a so-called hopping code for connecting and Decrypt data 42, such as that provided by the company Mikrochip Technologie Inc. under the name HCS 300 is offered, and a special for this property security system written software 44. The processor-controlled evaluation unit 40 can evaluate the signals received by radio and the component control accordingly, d. H. for example, the locking bolt or extend and / or the window or door lock is on standby move or switch off. In addition, the evaluation unit also evaluate the information received via sensors, d. H. determine whether the window or door is open or closed, or determine whether the locking bolt is retracted or extended, or determine whether an unauthorized opening is taking place, the component control accordingly and / or this information, for example as Alarm signal, pass on to other components. In other components can the evaluation unit after receiving an alarm signal Trigger alarm, i.e. depending on the component trigger the siren that Switch on the alarm lighting and / or activate the telephone dialer. Details of this are described below.

By using one and the same communication element 40 in all components is a direct communication of all components possible with each other, so that the previously necessary detour via There is no central office and short response times can be achieved. Of Furthermore, this makes it very difficult for an unauthorized person to Property security system to put out of operation, because he has several Components should be put out of operation at the same time, which is in practice not possible.

Furthermore, a learning program 46 is integrated in the evaluation unit 40, through which each component is put into operation. Here will every component used by the legal user for the first time assigned a code number by the tutorial that can be User or a craftsman determined independently from the tutorial and the respective component is communicated. At the later in operation The communication between the components takes place respective component only react to the received signals, if it has recognized its own code number. This tutorial 46 works so independently that no craftsman or specialist is involved are needed, increasing the risk of spying through such third parties is reduced to a minimum.

The control unit 10 includes a keyboard and a display 48, as well as that Communication element 34. In addition, the control unit 10 another voice output 50 so that all from the control unit 10 on Information to be passed on to the user in writing via the Display 48, as well as given acoustically via voice output 50 become. In addition, the control unit 10 still has the above Described tutorial 46, using the new components in the Property security system can be integrated.

In Figures 3, 4 and 5 is an embodiment of an inventive Door or window lock 14, 16 shown. The safe lock 18 is constructed analogously. The door and window lock 14, 16 comprises a rigid frame 54, preferably of aluminum, on the latter Underside of a printed circuit board 56 having electrical lines is embedded while on the top of the frame 54 an electric movable locking member 58, a door or window lock powered 9 volt battery 60 and a position sensor 62 are accommodated.

The locking member 58 includes an electric motor 64 which has a spindle 66 drives. This spindle 66 is made so long that it is longitudinally displaceable supported, hollow cylindrical guide element 68 protrudes, a corresponding counter thread is formed on the inside. On the guide member 68, a crossbar 70 is rigidly attached carries two locking bolts 72 arranged parallel to one another. In the the position shown in Figure 3, the locking bolts 72 are complete extended and extend into corresponding, in a counterpart 74 of the Door or window lock 14, 16 recessed locking openings 76 in. The electric motor 64 working as a DC motor rotates the Spindle 66 with appropriate polarity such that the guide element 68, the crossbar 70 and the locking bolts 72 deeper into the frame 54 are pulled in so that the locking bolt 72 is the counterpart 74 release as soon as the guide element 68 in its end position has arrived.

On an outer edge of the guide element 68 there is an approximately 2 mm wider Round magnet 78 inserted, which is positioned so that it is complete retracted guide element 68 a first reed contact 80 and at completely extended guide element 68 a second reed contact 82 is opposite. These reed contacts 80, 82 and the magnet 78 are part of the position sensor 62, the respective reed contact 80, 82 always forwards a signal to the evaluation unit 40 as soon as the Magnet 78 is recognized. This can on the one hand achieve the desired position of the guide element 68 or the locking bolt 72 can be detected, so that the electric motor at this moment can be switched off and on the other hand by appropriate Activating the reed contacts 80, 82 can be determined in which Condition the locking bolt 72 and thus the entire door or Window lock 14, 16 is located. This status information is sent to the control unit via the evaluation unit 40 and the transmitter 38 10, 12 forwarded so that the user on the display 48 of the control unit 10, 12 can read whether the desired door or the desired Window is currently locked or not.

On the front side of the frame 54 of the door or window lock 14, 16 a condition sensor is attached, which also has reed contacts 84 and 86, and two correspondingly arranged magnets, not shown here in the counterpart 74 includes. Via these reed contacts 84, 86, the The status of the door or window can be queried. That is, as soon as the Reed contacts 84, 86 with the corresponding magnets in the counterpart 74 are aligned, a corresponding signal is sent to the evaluation unit 40 with which it is identified that the door or the window closed is. If the reed contact 84, 86 does not match the corresponding magnets in counterpart 74 are aligned, so the reed contact 84, 86 also send no signal and the evaluation unit 40 then knows that the door or window is not closed a corresponding information to the display 48 or the voice output 50 forward the control unit 10 or 12.

These reed contacts 84, 86 of the condition sensor continue to serve as intrusion detectors, because once these reed contacts 84, 86 are in focus Property security system from the area of activity opposite them lying magnets, this is an indicator of a unauthorized opening of this door or window. That is, as long as the The property security system is in operation, i.e. is in focus, sends the Evaluation unit 40 always an alarm signal when the reed contacts 84, 86 from the field of activity of the opposite Magnets are brought out.

Depending on the embodiment, this alarm signal is encrypted or unencrypted forwarded to a UHF transmitter 38 which receives this alarm signal then broadcasts at a frequency of approximately 434 MHz.

The UHF transmitter 38 is together with the UHF receiver 36 on one Board 88 attached in the rear area on the underside of the frame 54. The receiving antenna 90 connected to the UHF receiver 36 and the transmit antenna 92 connected to the UHF transmitter 38 are both in one extending over almost the entire length of the frame 54 Groove 94 recessed and are thus by the aluminum web 96 of the Printed circuit board 56 and the crystals 98 and ICs 100 located thereon separated so that mutual electromagnetic interference a minimum is reduced.

On the circuit board 56 are four integrated circuits (IC) 100 and four quartzes 98 operatively connected therewith, a circuit for Device for encrypting and decrypting data 42 is one where Circuit is designed as a clock 110, a circuit the Main processor with software 44 and tutorial 46 includes and wherein a circuit is used to control the electric motor 64, so that each IC 100 has a special task.

Furthermore, a light-emitting diode 104 is attached to the printed circuit board 56, which lights up during the processing time of a certain process, so that the user thereby receives the control information that his desired operation is actually carried out.

In addition, a switch 106 is attached to the circuit board 56, with the the learning program 46 is activated, in particular around the respective one Integrate components into the entire property security system.

Especially in the case of the window lock 16, there is a first inclination sensor in the web 96 108 is provided, which at an inclination of the window lock of 5 ° and more forwards a corresponding signal to the evaluation unit 40, so that the evaluation unit 40 is now informed that the window in question is tilted. Furthermore, the Window lock 16, a second inclination sensor, not shown here provided that at an inclination of the window lock of 15 ° and more forward a corresponding signal to the evaluation unit 40, so that the evaluation unit 40 is now informed that the the relevant tilted window was opened inadmissibly.

On the rear end face 112 of the frame 54 is a cinch connector receptacle 114 provided, in which a mini siren 116 is inserted holding. This depending on the need for the door and / or window lock 14, 16th attachable mini siren 116 is also addressed in the event of an alarm and generated directly on the door or on the window where the Burglars create and deafening noise thus drive the burglar into flight. In addition to this mini siren 116 the other components in the manner described here addressed so that a multiple alarm is realized. Via the cinch connector 114 is next to an electrical contact to the evaluation unit 40 also created a holding device that the small mini siren 116 reliably on the door or window lock without any additional aids 14, 16 holds.

Each component has the same communication element 34 and the Programs necessary for communication, which are part of the software 44 so that each component is able to send signals to one or sending out multiple components and signals from different Receive components. Electricity is used to operate the component needed in the property security system according to the invention provided exclusively via the integrated 9 volt battery becomes. To minimize power consumption and thus the battery average lifespan of 1 to 2 years is reached Radio operation clocked. For this purpose, the clock generator 110 otherwise switches the switched off UHF receiver 36 only every 5 s for a period of about 100 ms on reception. If a radio signal is received during this time, so this radio signal from the device for decrypting Data 42 is decrypted and the code number contained in the radio signal is compared with the code number of the respective component. Do they agree If the two code numbers do not match, the UHF receiver 36 switches on out again. However, if the two code numbers match, the code goes UHF receiver 36 latches for a few seconds and waits for it Main signal with the commands to be carried out. About five seconds after the last signal received or after a corresponding command the UHF receiver 36 turns off again until the next clock appears. This will reduce power consumption to a minimum. It is understood that the respective UHF transmitter 38 with the distant signal relevant code number permanently over a period of 6 s to 7 s send out so that each component receives this distant signal.

The UHF transmitter 38 transmits its signals at a frequency of approximately 434 Mhz. Since it is theoretically known to an unauthorized person if this frequency is known it is possible to communicate individual components by sending them out The door or window lock has an interference signal 14, 16 a second transmitter 118, which is in the ultrasound range sends. Because the ultrasonic radio signals are only in visual contact from one with the ultrasound transmitter 118 standing ultrasound receiver 120 Such ultrasonic receivers 120 can be received in the relevant rooms. As shown schematically in Figure 6 is such an ultrasound receiver, for example on a telephone or Power socket 122 be attached and those received by him Signals then over the telephone or power cable network in the house 124 to siren 28, telephone dialer 30, or other components hand off. That is, the door or window lock 14, 16 an unauthorized person, for example, perceived by the state sensor Opening the door or window in the form of both via radio 126, as also send alarm signals to other components via ultrasound 128 as the siren 28 or the telephone dialer 30 reports, which then Trigger alarm. This double protection increases the reliability of the Object security system according to the invention clearly and makes a Tampering by unauthorized persons is difficult.

To detect a violently destroyed window or door pane is in a glass break microphone is installed in the window and / or door lock. This broken glass microphone is set so that only when receiving the noises typical of glass breakage (noises with a typical Frequency response) a corresponding signal is sent to the evaluation unit becomes.

Another special feature of the property security system according to the invention is the formation of a tilt window counterpart 130 of the window lock, which is shown schematically in Figures 7 to 9, wherein the window shown shows the respective tilt position and where the Window lock 16 and the tilt window counterpart 130 enlarged are shown. In contrast to the counterpart 74 described above the classic door or window lock 14, 16 has the tilt window counterpart 130 two locking openings formed as curved elongated holes 132 and two magnets 134 and 138. The elongated holes 132 are designed so that despite being locked and focused Property security system either the left, the right or both windows can be set on tilt and the locking bolt 72 still engage in the locking openings designed as an elongated hole 132. The magnets 134 and 138 are thus on the tilt window counterpart 130 arranged that the magnet 138 always with each position of the window the reed contact 86 is operatively connected, so that in the case of a Intrusion via the reed contact 86 the alarm can be triggered.

Furthermore, the evaluation unit 40 can query the reed contact 84 and the inclination sensor 108 the exact state of the capture each window and via the display 48 or the voice output Play 50. As can be seen in Figure 7, the upper reed contact 84 always in operative connection with the upper magnet 134, if both windows are in the same position, that is, if both Windows are either open or closed. Whether the windows now are opened or closed is determined via the inclination sensor 108. As can be seen from FIGS. 8 and 9, the lower reed contact is 86 always in operative connection with the lower magnet 138, if one of the windows is tilted. Via the tilt switch 108 The evaluation unit 40 can then determine which window is tilting stands and which window is closed.

As a result, all states can be recorded and displayed, and for each conceivable condition is a reed contact 84, 86 in use, which in the event of a break-in can trigger the alarm. This makes the window possible tilted to lock and secure and still some ventilation of the room.

In an embodiment not shown here is in the tilt window counterpart 130 another magnet is provided in the contact area of the reed contact 84 is arranged. Now becomes the counterpart 130 or the window lock 16 removed without authorization and / or their presence simulated by another external magnet, this solves another magnet emits a signal which is sent to the evaluation unit 40 is forwarded.

In Figure 10, the hand control unit 12 is shown in an enlarged view. Analogous to the permanently installed control unit 10, the manual control unit also has 12 the complete communication element 34, a common one Keyboard, a display 48 and optionally also a voice output 50. Die Hand control unit 12 is approximately the size of an otherwise for television or the like known remote control and with this hand control unit 12, the user can see the state of the particular door or the determine the respective window and / or individual or all doors or Lock windows if they are closed. Because this hand control unit 12 is kept very small, the user can use it anywhere in the house take away and the property security system from its respective location operate from. Furthermore, it is also possible to use the hand control unit 12 to take away and the property security system from the outside control as long as the transmission power of the UHF transmitter 38 is sufficient to Send signals to the UHF receiver 36 of the desired component. It is assumed that a range of approx. 100 m is likely for this is sufficient. Thus, the property security system as a whole or at least the front door when leaving the house via the hand control unit 12 activated and deactivated when returning.

In addition, the manual control unit 12 can still be operated via an SOS button 140 and / or have a quick lock button 142. With pressing the SOS key 140 activates the telephone dialer 30 and dialed a specific, previously entered telephone number and / or the Siren 28 activated so that the user with the SOS button in the event of a acute health problem quickly and easily help, for example a doctor or a relative. With the quick lock button 142, the user can push all windows at the push of a button or lock doors where this is currently possible so that the When noticing an approaching burglar, users quickly find the otherwise can lock unlocked windows or doors.

So that in the event of a technical defect in the door lock 14, one empty battery and / or in the event of loss of the manual control unit 12 the user can still get into his home is preferred Emergency release counterpart 146 to be attached to the front door a door lock 14 is provided, which is shown schematically in FIG is. This emergency release counterpart 146 consists of one Base part 148 and a pivotally attached to the base part 148 Top 150 together, with top 150 and base 148 over a conventional electric strike, not shown here (also Called buzzer). In addition, in the base 148 is a very weakly sensitive UHF receiver with a short receiving antenna, a device for decrypting data already described above and an integrated circuit with the tutorial 46 is provided, so that the emergency release counterpart 146 is just like the other components can be assigned a code number by unauthorized persons cannot be read out. In an emergency, the emergency release counterpart can 146 both from the hand control unit 12 and from one special emergency release control unit can be operated, according to Receiving a corresponding signal with the correct code number Electric door opener (buzzer) unlocks the upper part 150 and folds away, see above that the front door can now be opened. Because the UHF receiver is very is insensitive, the user must be very close to his control unit approach the emergency release counterpart 146 for a transfer the signals can take place. The emergency release control unit is a very small and reduced to the most necessary hand control unit, the only a weak UHF transmitter, an integrated circuit with the Tutorial, mini display, mini keyboard and indicator light having.

This door or window lock 14, 16 described here is due the very space-saving spindle construction and very compact shows despite the comparatively thick and stable locking bolt 72 with a diameter of 10 mm only a height of 32 mm, a Width of 60 mm and a length of 105 mm (with mini siren 116 a Length of 125 mm). Because of these small dimensions, this is approximately Cigarette-box-sized door or window locks 14, 16 Existing doors and especially windows can be attached without the aesthetic Overall impression severely impaired, because the window lock 16 is not wider than the window frame. Through this, and because of the The fact that this property security system is completely wireless, is retrofitting in an existing building or apartment in simple and inexpensive way possible. The following is the use of the property security system according to the invention described in more detail:

The components of the property security system shown in the figures are installed at a suitable location in or on the building to be secured. It can be done on complex laying of data and / or power cables be dispensed with, since the components have their own battery with electricity be supplied and since communication with other components via Radio done. After the necessary components are assembled, from the control unit 10 the commissioning of the property security system, especially the individual components. The components should be started up individually and one after the other. For this purpose, the factory-preset, Enter four-digit PIN number and should immediately by an individual PIN number replaced. Now by entering appropriate commands in the control unit 10 started the learning program 46. The entry is made in dialogue with the control unit 10, the information from the Control unit 10 to the user via the display 48 and / or the Voice output 50 are output.

After the control unit 10 is ready for operation, in each case in Operating component of the switches 106 are actuated, so that the learning program 46 is also called up in the component. Now The control unit 10 determines a using the software that is resident in it Code number, which is then encrypted to the relevant component is sparked. This code number is stored in the respective component and serves as an address. Since this commissioning is fully automatic expires, neither the user nor a stranger (installer) knows the concerned Code numbers, which offers the highest level of security. As soon as the components provided in the object can be put into operation the property security system can be used. If you upgrade later, Expansion or modernization of the property security system can the new components are put into operation in an analogous manner.

To activate the property security system, the user must log in his PIN first access to the control unit 10 or to a manual control unit Procure 12. It doesn't matter which control unit it is used because the property security system with any control unit can be operated. Now the user can determine by query which doors and / or windows are open and closed and needs no longer run through the whole house to close the doors or windows check. In addition, the user can now use the closed doors and lock and / or focus windows with the control unit. Here the user can open the doors and windows individually, in groups or all operate at once. While the door or window lock locked, the LED 104 lights up for control purposes. Because the UHF radio signals don't let obstacles influence you the user's current location is irrelevant.

The control unit 10, 12 also transmits before the transmission of the main signal an encrypted distant signal with the commands to be executed the code numbers of the components to be addressed over a period of time from 6 s to 7 s. Since the individual components with a clocking of If the device is on standby for 5 seconds, each component receives the transmitted signal Distant signal and can decrypt it accordingly. After one Comparison of the sent code numbers with the own code number goes the UHF receiver 36 on hold if its code number was included and in the rest position if his code number was not there. Subsequently the control unit communicates with the respective component and switches the UHF receiver 36 of the component again as soon as the process is finished.

The control unit can use the sensors built into the components 10 and especially the hand control unit 12 before each operation current situation, that is, the position of the locking bolt 72, the Condition of the door / window, the tilt position of the window or Query the same, so that each control unit 10, 12 always for operation the property security system can be used, even if last another control unit was used. Since the hand control unit 12 can also be taken anywhere, it fulfills the same Function like a classic key or a remote control. Of the The user only has to remember the individual PIN number.

In the event that the property security system is in focus, the Reed contacts 84 and 86 and any existing sabotage contacts as an alarm if someone forcibly opens the door or window. In the event of glass breakage, the glass breakage detector issues, in the event of fire, gas or smoke There are gas, smoke or temperature detectors and intruders Motion detector according to alarm. If such an alarm is triggered, so sends the corresponding component in the manner described above an alarm command both via UHF radio and via ultrasound to the Siren, the alarm lights and / or to the telephone dialer, which then to become active. The respective components are addressed directly, without the detour being made through a central office. The Components activated in this way can be entered by entering a corresponding one Instructions by the user authorized by the PIN number in the Control device 10, 12 can be deactivated again.

Should the property security system change in an unforeseen way do not switch off or open the front door, it can users legitimizing the PIN by means of an emergency release 146 Provide access to the object. To do this, the user must either use the hand control unit 12 or with an emergency release control unit in the proximity of the emergency release counterpart 146 and enter via radio Send the signal to release the electric strike (buzzer). Then can the front door to be opened. However, at that moment, a Alarm triggered because the reed contact of the door lock opens the Perceives door. This alarm must then immediately, for example via the Control unit 10 are stopped.

With the manual control unit 12, the object security system can be carried out more conveniently For example, be operated from the sofa or from the bed. The SOS button can be used as a call for help, especially for older people an unforeseen accident or weakness the siren and / or the telephone dialer at the push of a button can be activated.

In a further embodiment, not shown here, the transmitter completely of a film provided with vapor-deposited conductor tracks surround. The transmitter is preferably directly surrounded by the film and inserted into the housing together with this. This slide is on one Signal generator connected, which then always sends a corresponding signal the evaluation unit passes on if at least two of these conductor tracks are shorted together or if at least one conductor track is interrupted. This is an effective protection against drilling created so that the property security system by Aufauf or Tapping at critical points can be deactivated.

The transmitter is advantageously together with a gold caps capacitor incorporated into the film so that the transmitter is sufficient even then Has energy to send the alarm signal when the Transmitter including foil has been separated from the rest of the system.
