Abstract

An addressable fire alarm system comprises a plurality of heat and/or smoke sensors 10 connected to a control panel 13. The sensors 10 are programmed with their unique address codes by successively activating them using a heat or smoke source, the control panel 13 being arranged to transmit successive address codes to respective sensors 10 as they are successively activated. Each sensor 10 receives and stores its unique address code that is received from the control panel 13. The address code of each sensor 10 is thus very straightforward to set. Moreover, the system makes it easier to group the location of the sensors 10 according to their address codes. <IMAGE>
