NOTIFIER N100-ISO Fault Isolator Module is used with FireWarden Series panels to protect the system against wire-to-wire short circuits on the SLC loop The N100-ISO 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. Features • Powered by SLC loop directly, no external power required.• Mounts in standard junction boxes (4.0"/10.16 cm square, 2.125"/5.398 cm deep).• Integral LED blinks to indicate normal condition. Illuminates steady when short circuit condition is detected.• High noise (EMF/RFI) immunity. Applications The Fault Isolator Modules should be spaced between groups of sensors in a loop to protect the rest of the loop. Use to isolate short circuit problems within a section of a loop so that other sections can continue to operate normally. The N100-ISO supports a maximum of 25 devices in-between isolators, except when using relay bases. NOTE: LOADS PER RELAY BASE AND ISOLATORS/ISOLATORBASES: The maximum number of addressable devices between isolators (or B224BIA isolator bases) is 25 devices.
