A security alarm network including a plurality of microprocessor-based, subscriber system controllers, wherein each controller is capable of responding to a plurality of distributed wireless and hardwired sensors/transducers and is programmable via user, central station and installer-entered system and network parameters. Each system controller is operable to (a) monitor neighbor system communications and system identification data; (b) maintain a central station programmable identification listing of neighboring systems and, if communication malfunctions occur, communicate with the central station via one or more cooperating neighbor controllers; (c) self-learn the identification data of its distributed sensors; (d) maintain operator and central station-accessible event histories; (e) self-confirm predetermined emergency conditions; (f) regulate communications with the central station relative to pre-programmed, grouped, arming level dependent responses and system parameters; and (g) enable audible monitoring by the central station.

In a security alarm network including a plurality of transducers, wherein each transducer communicates status data to a system controller of one of a plurality of subscriber systems and wherein each system controller communicates received transducer data to a central station, an improvement comprising: (a) at least one system controller including means for detecting an incapacitated communications link of said at least one system controller to said central station and further including means for transmitting an inability-to-communicate (IC) alarm to at least one other of said plurality of system controllers; and (b) means coupled to at least one other of said plurality of system controllers responsive to a received IC alarm for communicating the identity of the incapacitated system controller to the central station.
