Loop Isolator LI
Unipolar loop circuit Loop Isolator LI is designed to be used within address communication lines RS-R3 of receiving and control devices R3500 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.
