KC-FX-ISO KIDDE FIRE ALARM SIGNAL ISOLATOR MODULE

Description

The KC-FX-ISO KIDDE FIRE ALARM SIGNAL ISOLATOR MODULE is a field device used to protect and maintain communication integrity on Kidde FX-series fire alarm signaling circuits. It electrically isolates shorted segments of wiring so that a single fault does not disable the entire circuit. By maintaining supervision and enabling continued system operation beyond the fault point, this module supports reliable alarm and trouble reporting in addressable and conventional fire alarm networks.

• Model/SKU: KC-FX-ISO

• Brand: Kidde

• Function: Signal isolator that segregates faulted wiring segments on notification and signaling circuits to preserve system supervision and operation

• Circuit Protection: Automatically isolates shorted sections while allowing normal operation of unaffected segments

• Compatibility: Designed for use with Kidde FX-series fire alarm control panels and compatible signaling lines

• Supervision: Provides supervision of wiring integrity and fault status back to the panel

• Mounting: Module mounts in standard backbox or enclosure with accessible wiring terminals

• Application: Used on notification appliance circuits (NACs) or other supervised fire alarm wiring to prevent a single short from disabling the entire loop

• Why It Matters: Enhances system reliability and fault tolerance by isolating wiring failures — minimizing nuisance trouble signals and maintaining active protection across the rest of the circuit.
