Firelite I300

The Fire-Lite I300 is a Class A fault isolator module designed to protect addressable fire alarm signaling line circuits from wire-to-wire short circuits. Powered directly by the SLC loop without external power, the I300 includes built-in LED indicators that blink green during normal operation and turn solid when a short-circuit condition is detected.

Key Features

• Direct SLC loop power integration—no external power supply required
• High EMF/RFI immunity for reliable operation in electrically noisy environments
• LED indicators: green blinking (normal), solid red (short-circuit detected)
• Supports up to 25 devices between isolators (except relay bases)
• Standard mounting in 4" square junction box (2.125" deep minimum)
• Off-white plastic faceplate
