The FireLite I300 Fault Isolator Module is used with the MS-9200 to protect the system against wire-to-wire short circuits on the SLC loop. The I300 should be placed between each device on the SLC loop, to isolate a short-circuit problem be- tween the modules. It is required for true Style 7 operation so that other de- vices can continue to op- erate normally in the event of a short-circuit on the SLC.FEATURESPowered by SLC loop directly, no external power required.Mounts in standard 4-inch square (2-1/8" deep) junction boxes.Integral LED blinks to indicate normal condition. Illuminates steady when short circuit condition is detected.High noise (EMF/RFI) immunity.General InformationName: Isolator Module Required for Style 7 Class A SLC, Fire-Lite Alarms, Fire-LiteCategory: Fire-lite Alarms By Honeywell, Fire, Fire Accessories, More Fire AccessoriesUPC Code: 783863000546Country of origin: United States.
