FIELD: intruder alarms, methods for transferring signals in alarm signaling systems, in particular, from alarms to control-receipt devices via signaling loops.
SUBSTANCE: detector of alarm contains data processing device, which is connected to device for generation of output signal in form of commutator. As commutator, alarm contains electronic key.
EFFECT: lower costs of intruder alarm system due to decreased number of network power sources and power cords.
