- FIG. 1 is a schematic block diagram of a security system in accordance with one form of the present invention.
- FIG. 2 is a schematic block diagram of a sensor in accordance with one form of the present invention. For simplicity, power supplies supplying each block have not been shown.
- Figure 3 is a schematic block diagram of a prior art wireless security system.
- the alarm panel also known as a security panel or control panel
- the central station calls up the central station and gives an electronic message to the answering computer. It tells the computer exactly which switch or sensor has been violated, and the computer then tells the operator what has happened. For example, if a burglar entered through a broken window, the panel would connect with the computer and tell it that zone 4, a first floor window, has been broken. The operator would then see on his computer screen a display indicating, for example, that in the Johnson residence, in zone 4, the foil on the living room window, violated.
- the panel would call the computer for every sensor that was violated.
- the operator may then receive status that in zone 17, a passive Infrared detector in the master bedroom, has detected someone.
- pre-amplified microphones allow audio monitoring of the protected premises.
- the operator would then be fairly sure someone was in the house, so the operator would have three options.
- the operator may just send the companies guards to the scene, call 911 and dispatch the police, or the operator may send both the police and the guards.
- Passive infrared alarms are so called because they do not emit Infrared energy, but merely detect a change in Infrared energy.
- a PIR sensor probes its monitoring area, and if any changes are detected in Infrared (heat), it triggers an alarm.
- a PIR records the ambient room temperature so it will notice any changes in IR such as those that are produced by the human body. Slow temperature changes, such as thermostatically controlled heating systems, will not interfere with the PIR's function.
- a conventional sensor such as a passive infrared (PIR) sensor 2 having a single sensitivity level operatively connected.
- the sensors 2 utilize switches (not shown) to connect one of a plurality of sensitivity levels at any given instant, are coupled to a battery 4, and include an internal transmitter and an antenna for transmitting a signal corresponding to the sensed parameter.
- PIR passive infrared
- a battery 4 is coupled to a battery 4, and include an internal transmitter and an antenna for transmitting a signal corresponding to the sensed parameter.
- Commercially available devices of this type are manufactured and sold by Honeywell and identified by the designation Ademco 5890 or 5894.
- the wireless sensor 2 is constructed and programmed to issue a signal at a predetermined interval to confirm the presence and operability of the sensor 2. For example, such a signal may be sent at an interval of once every hour to confirm to an alarm panel that the sensor has not been stolen or become inoperative.
- the signal from the sensor 2 is transmitted to a receiver 6 that is configured to receive the signal from the sensor 2.
- a receiver 6 that is configured to receive the signal from the sensor 2.
- Commercially available devices of this type are manufactured by Honeywell and are identified by the designation Ademco 5881.
- the receiver 6 is physically connected to an alarm panel 8.
- a commercially available alarm panel 8 for such an application is manufactured by Honeywell and identified by the designation VISTA 50.
- the alarm panel 8 is coupled by a phone line to a microcomputer running control software whereby the alarm panel 8 may be remotely controlled.
- a microcomputer running control software whereby the alarm panel 8 may be remotely controlled.
- One commercially available software program for such purposes is marketed by Honeywell and identified as the Ademco Compass
- This software permits a user to remotely program and control an alarm system. The user may do so from the comfort of an office and will allow the user to download and upload alarm control information, to compare the upload and saved information, and to view the results either on a screen or any printed report.
- the Compass Downloader enables programming from an office prior to installation. Alternatively, initial programming can be downloaded from a remote location or at a job site using a personal computer with a commercially available serial module such as the Honeywell/Ademco
- the Ademco Compass Downloader for Windows Software 10 is network compatible software that provides a quick and easy method for planning, designing and communicating with the alarm panels. With this software the user can upload system programming that has been manually entered into the panel, or previously downloaded.
- the Compass change feature reviews all system changes initiated by the download operator within the current session. A complete record of system modifications and the history of an account are also available.
- the installer will choose the sensitivity of the sensor 2 by setting switches (not shown) within the housing of the sensor 2. If, at a later date, it is determined that the switch setting within the housing is not correct, the installer will be required to return to the worksite and to the sensor 2 to change the settings.
- FIG. 1 and 2 there is shown respective parts of schematic block diagram of a security system in accordance with one embodiment of the present invention. While the invention has application to at least glass break, asset, dual technology, motion, temperature and shock sensors the block diagram illustrates only a passive infrared sensor 18, a glass break detector 20 and a temperature sensor 22.
- the passive infrared sensor 18 may have varying sensitivities such as to the number of steps that an intruder has taken within the protected premises.
- the temperature sensor 22 may have different sensitivities corresponding respectively to cold, warm and hot.
- the glass break detector 20 may have respective sensitivities respectively corresponding to the distance between the detector and the protected glass.
- Each of the sensors 18, 20, 22 is a wireless sensor that communicates with a receiver 16 coupled to an alarm panel 12.
- the alarm panel 12 has incoming communication 17 and outgoing communication 14 via telephone, Internet or other communications networks such as the ALARMNET communications system.
- the ALARMNET communications network is a nationwide service provider delivering a wide range of products and services for supervised alarm signal transport applications.
- the ALARMNET communications network is operated by Honeywell. Referring now to Figure 2 there is shown a block diagram of a typical sensor, such as a passive infrared sensor 18, a glass break detector 20 or a temperature sensor 22, together with associated circuitry for cooperation with the apparatus shown in Figure 1.
- the types of sensors to which the invention pertains include, but are not limited to, glass break, asset, dual technology, motion sensors, temperature sensors and shock sensors.
- Each of the sensors 18, 20, 22 may have a plurality of discrete outputs corresponding, for example, to low, medium and high sensitivity settings and means to remotely configure the sensitivity of the sensor by remotely connecting one of the plurality of discrete outputs
- the sensor outputs a signal for each sensitivity threshold. For example, if the PIR has one, two, and three footstep thresholds, an alarm output will be sent after the intruder takes one step; a second output will be sent after the intruder takes a second step; a third output will be sent after the intruder takes a third step.
- the control panel will receive ail of these signals and must be programmed to respond to only one. The programming can be done at the keypad or remotely via the Compass program.
- the available loop numbers of the sensor are assigned to the different sensitivity settings required.
- the installer chooses the wireless loop number associated with the desired sensitivity.
- the installer can use a downloader to remotely change the loop number operatively connected to the panel 12.
- Each sensor for example a passive infrared sensor (PIR) 18 may have multiple outputs that are respectively produced (triggered or alarmed) in response to three discrete sensitivity levels.
- the sensor may have low, medium and high sensitivity outputs. These outputs may, for example, correspond respectively to an intruder that has taken three, two, or one steps within protected premises.
- the output of each sensor 18, 20, 22 is connected to a signal conditioning circuit 24 in the customary manner.
- the output of the signal conditioning circuit 24 is connected to a microcontroller 26.
- the microcontroller is chosen from the MSP430 series from Texas Instruments.
- the MSP430 is an inexpensive ultra-low power RISC based microcontroller.
- the high sensitivity output When a weak motion signal is detected, the high sensitivity output would go into the alarm state and an alarm signal would be transmitted to the panel. If a strong motion signal is detected all three signals will be transmitted to the microcontroller, then to the panel.
- the panel is programmed to only respond to the loop associated with the desired sensitivity setting. For high sensitivity, the panel is programmed to respond to the loop number 3 transmissions. Programming of the panel 12 can be done locally at a keypad or remotely via the phone line.
- the embodiments that include an Application- Specific Integrated Circuit include a chip designed for a particular application (as opposed to the integrated circuits that control functions such as RAM in a PC).
- ASICs are built by connecting existing circuit building blocks in new ways. Since the building blocks already exist in a library, it is much easier to produce a new ASIC than to design a new chip from scratch.
- ASICs are commonly used in automotive computers to control the functions of the vehicle and in PDAs.
- the respective methods and systems in accordance with the present system may utilize a microcomputer that includes a microprocessor and memory and which cooperates with software that is commercially available or within the skill of practitioners in the programming arts. Although the present invention may employ an ASIC, those skilled in the art will recognize that in other embodiments discrete components may be utilized.
- the embodiments utilizing a microprocessor and memory will use software known or obvious to those skilled the art.
