A system for preventing unauthorized access to the programming and control features of remote sensor transmitters (4A) utilized in a remote sensor/transmitter array, such as, for example, fire and/or security systems (4C) or the like. The exemplary embodiment of the present invention utilizes an association of transmitter identity/address with a central processor/control fire/security data base (4I) which in turn is configured to securely program each transmitter with its location and function, or "personality". Still other teachings of the present invention relate to a sensor transmitter (4A) which is shipped in a power saving mode, and which powers up upon sensing predetermined conditions, said sensor further including power saving transmission modes, EEROM power saving modes and redundant memory with error checking features, optical and magnetic loop power/programming systems, and a unique sequence of events "wake up" string. |
