Abstract
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.
