Intelligent fault isolator modules are addressable and designed for use with the Honeywell Silent Knight® fire alarm control panels. They act as an automatic switch that opens when the line voltage on the signaling line circuit (SLC) loop drops below 4V. Intelligent fault isolator modules are intended to be spaced between groups of sensors or modules in a loop to protect the rest of the loop in the event of a short. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit and isolate the devices between them, allowing the remaining units on the SLC loop to continue to operate.

Features & Benefits:

LED that flashes green during normal states, and turns a solid red during an alarm

Isolates short circuits on an SLC loop

Protects the modules on the SLC loop so that other devices can continue to operate

Standard 4 inch electrical box mounting
