FIELD: fire-alarm equipment.
SUBSTANCE: system includes fire and protection alarms, control devices and end devices, connected via radio to territorially spread network of relays. Alarms received by relays as well as service or control-diagnostic messages are sent further by radio or cable channels to centralized guard station, connected to phone network and outer information sources and made with possible two-side radio communication to foot and mobile operative response forces around objects. Radio stations of teams are made with possible receiving of alarms from end devices of objects and/or relays, decoding received alarms, transforming alarms to voice messages through radio speaker as well as with possible visualization of guard zone plan, wherein alarm took place, on radio station display.
EFFECT: higher efficiency.
