Abstract

A security system for sensing the status of various security detectors used in, for example, home security such as fire, intrusion, emergency and appliance operation protection is disclosed. The detectors transmit, usually via radio frequency, various messages to a central monitor. To enable proper communication, the transmitters are programmed to transmit messages unique to the originating detector. The transmitters may be programmed at one station and then moved to the detector for insertion therein. During this transport, it is important that a volatile memory of the transmitter be retained. This is accomplished by a low power source. A disarming device is provided to disarm the transmitter during transport to prevent the transmitter from draining a short term power source by transmitting a message. This avoids the loss of any programmed information in the evaporative memory.
