DEVICE FOR PROTECTION AGAINST IMITATION OF GROUP OF CONTROLLED OBJECTS Russian patent published in 2016 - IPC G08B25/00 

FIELD: fire safety.

SUBSTANCE: invention relates to security and fire alarm systems, in particular to devices for controlled objects protection against falsified data entry, and can be used for protection of objects. Said objective is achieved due to that existing device for protection against imitation of group of controlled objects, comprising a control and display unit, N≥2 sensors (2₁, 2₂…2_N), further includes M≥2 interface units (3₁, 3₂…3_M), wherein number of sensors matches number of interface devices of (N = M), that provides higher reliability and stability of operation under conditions of failure of one or more sensors, reduced probability of penetration of an intruder and time for detection of said fact, easy switching of sensors and control and display unit at any number of sensors, which significantly widens field of use of device, widens functional capabilities of existing devices for signalling state of controlled objects.

EFFECT: aim of invention is designing a device capable of providing higher reliability of whole device in case of failure of one of sensors, having proper level for protection against imitation and enables to determine a controlled device, on which acts a malicious user, over a short period of time.
