Fire-Lite I-300 Fault Isolator Module for Fire Alarm Control Panels

Protect your addressable fire alarm network and maintain continuous monitoring with the Fire-Lite I-300 Fault Isolator Module from Fire-Lite Alarms by Honeywell. Designed to isolate wire-to-wire short circuits on the Signaling Line Circuit (SLC), the I-300 preserves the operation of other devices on the loop so critical security and fire detection functions remain active. The module is powered directly from the SLC (28V DC), eliminating the need for external power supplies and reducing installation complexity. An integral LED offers immediate visual status—blinking in normal conditions and steady on when a short is detected—so technicians can quickly pinpoint issues and restore service. The compact I-300 mounts in standard junction boxes and features high EMF/RFI immunity for dependable performance in electrically noisy environments like data centers, surveillance hubs, and commercial buildings. Rated for operation from 0°C to 49°C, it supports true Style 7 configurations for enhanced system resiliency. Specify the Fire-Lite I-300 to harden your fire alarm control panels and improve uptime—order or consult our technical team for application guidance.
