Fault Isolator Module HM-DISO-UL
Fire Projects recommend the HM-DISO-UL Fault Isolator Module is used with the fire alarm control panels (FACPs) to protect the system against wire-to-wire short circuits on the SLC loop. The HM-DISO-UL 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.
