I300 Fault Isolator Module
I300 fault isolator modules are designed for use with Fire-Lite® addressable fire alarm control panels (FACPs) and are intended to protect systems against wire-to-wire short circuits on SLC loops. These fault isolator modules should be placed between each of the devices on the SLC loop to isolate a short-circuit problem between the modules. It is required for true Style 7 operations so that other devices can continue to function normally in the event of a short-circuit on the SLC.
