LPCB Addressable Fire Alarm System Loop Isolator Module for fire alarm system

AW-D314 loop isolator (hereinafter referred to as AW-D314), mainly used to isolate a portion of a short circuit on the bus, other devices on the bus to ensure normal operation. Upon elimination of the short circuit fault, AW-D314 can be isolated out their own part back into the system. It is worth noting: AW-D314 using the bus to facilitate the determination of the location of a short circuit.
