Fire-Lite I300 Fault Isolator Module

The Fire-Lite I300 is an intelligent fault isolator module for Fire-Lite addressable fire alarm control panels that helps protect the SLC loop from wire-to-wire short circuits. It automatically isolates the shorted section so the rest of the loop can continue operating, and it is required for true Style 7 operation. Key Specifications: Type: Intelligent fault isolator module Core Function(s): Automatically detects, isolates, and restores wire-to-wire short circuits on the SLC loop Loop/Protocol: Fire-Lite SLC loop Power: Powered directly by the SLC loop; no external power required; 15 to 32 VDC operating voltage Indicators/UI: Integral yellow LED pulses during normal operation and lights steady when a short circuit is detected Circuit Configuration: Used on SLC loops to isolate short-circuit faults and support Style 7 operation; also commonly used at T-tap branches on Style 4 loops Addressing: Non-addressable; automatic operation with no address setting required Device Spacing: Supports a maximum of 25 addressable devices between isolators, except when relay bases are used Mounting: Mounts in a standard 4 inch square junction box at least 2.125 inches deep Construction: Off-white plastic faceplate Compatible Accessories: SMB500 - Optional surface-mount backbox System Compatibility: Compatible with Fire-Lite addressable fire alarm control panels
