ISO-X Isolator Module

Description

The ISO-X Isolator Module is an essential component used in intelligent addressable fire alarm systems to enhance system reliability and protection. Designed by Notifier (Honeywell), this module is specifically used with ONYX and CLIP series fire alarm control panels to safeguard the Signaling Line Circuit (SLC) from wire-to-wire short circuits.

In the event of a short circuit, the ISO-X module automatically isolates the affected section of the loop, preventing the fault from disrupting the entire system. This ensures that the remaining devices on the loop continue to function normally, maintaining fire detection and alarm capabilities in other areas of the building. Once the fault is cleared, the module automatically restores the loop to its normal condition without manual intervention.

The module is powered directly from the SLC loop, eliminating the need for an external power supply and simplifying installation. It features a built-in LED indicator that blinks during normal operation and remains steady when a fault condition is detected, allowing easy identification during maintenance. With high immunity to electrical noise (EMF/RFI) and support for multiple wiring styles (Class A & B), the ISO-X module is widely used in commercial, industrial, and high-rise buildings to improve system survivability and fault tolerance.

Overall, the ISO-X Isolator Module plays a critical role in modern fire alarm systems by ensuring continuous operation, minimizing system downtime, and enhancing safety during emergency conditions.
