Fire-Lite's I300(A) Fault Isolator Module is used with the MS-9050UD, MS-9200UDLS, and MS-9600 to protect the system against wire-to-wire short circuits on the SLC loop. The I300(A) should be placed between each device on the SLC loop, to isolate a short-circuit problem between the modules. It is required for true Style 7 operation so that other devices can continue to operate normally in the event of a short-circuit on the SLC.
