GSTDC-M9503 Loop Isolator Module

In fire alarm system, such condition often occurs that partial short circuit of loop affects the whole system. DC-M9503 Loop Isolator Module (hereinafter referred to as the isolator) can isolate the shorted circuit from the whole system to ensure normal operation of other devices and help locate the devices in fault. After the short circuit fault is cleared, those devices will be re-introduced into the system. The isolator is suitable for use in Signaling Line Circuit (SLC) of addressable fire alarm system. Isolation of short circuit, automatic restore when short circuit is cleared. Support Class A SLC loop Standard: UL864 NFPA [70.72]
