METHOD FOR REMOTE CONTROL OF OPERABILITY OF SECURITY ALARM DEVICES AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC G08B29/00 

FIELD: physics.

SUBSTANCE: invention relates to the field of security equipment when establishing remote control (RC) of operation of detectors. At that, in each annunciator connected to receiving-control device (RCD) via communication cable with separate wire for RC mode switching or via two-wire communication and power supply line, or via a wireless communication line, an impact simulator is introduced, which is periodically activated upon command from the RCD and which directly affects the detecting element of the detector or system of sensitive elements, which is similar in physical nature to the effect of the intruder at a minimum level. RCD automatically analyses responses from detectors to RC command and determines their operability. Command of RC start for detectors with wire communication with RCD is performed by means of polarity reversal of supply of detectors, one or several times with certain time relations of polarities. Power inside the detectors remains constant due to rectification and stabilization, and the command along the supply circuit is detected by the detectors and switches them to the RC mode. Response signal on the result of verification is transmitted to the communication line with the RCD with a strictly defined and different for each specific detector delay relative to the command of the RC.

EFFECT: technical result consists in improvement of reliability of detectors and means of protection in general.
