Unipolar loop circuit insulator IZ-1 prot.R3 is designed to be used within address communication lines RS-R3 of receiving and control devices Rubezh-2OP prot.R3, Rubezh-KAU1 prot.R3, and Rubezh-KAU2 prot.R3 incorporated into fire alarm and fire extinguishing system RUBEZH. Loop circuit insulator insulates short-circuited sections of address communication line thus ensuring functioning of the rest part of a communication line. When short circuit condition is reset, loop circuit insulator automatically restores functioning of address communication line.
Optical tester OT-1
Optical tester OT-1 is intended for remote testing of addressable fire detectors of Rubezh brand. The tester is powered from three AG 13 batteries with rated voltage of 1.5 V.
