In loop type fire alarm system, it often occurs that partial short circuit of loop affects the whole system. C-9504E Base Mount Short Circuit Isolator can isolate the shorted circuit from the whole system to ensure normal operation of the remaining parts and locate the failed part by illuminating a yellow indicator. When the short circuit fault is cleared, the shorted part will be
☆ Nominal Line Voltage ( V NOM ) : 24V
☆ Standby Current : <100μA
☆ Capacity : 70 devices
☆ Indicator : Yellow. It flashes in normal standby state, constantly illuminates in action.
☆ Wiring : two-wire
☆ Automatically isolating short circuit part on the loop and automatically restoring it when short circuit is corrected.
