LI Loop Isolator
The LI loop isolator is used within RS-R3 addressable communication lines of the R3500 receiving and control panels built into the RUBEZH fire alarm and fire extinguishing system. Loop circuit insulator is designed to insulate the short-circuited sections of the addressable communication line thus ensuring functioning of the communication line rest part. When the short circuit is reset, the loop insulator automatically restores functioning of the addressable communication line (ACL).
