Loop Isolator Module GST C-9503

– In loop type fire alarm system, it often occurs that partial short circuit of loop affects the whole system. C-9503 Loop Isolator can isolate the shorted circuit from the whole system to ensure normal operation of other parts and locate the isolated part.

– Polarity-sensitive external connections. Input and output can be used inversely without direction.

– Delayed power-up to output end devices, avoids strong transient current when the load is heavy.

– Plug-in structure.

– Standards: EN 54-17:2005/ UL864/NFPA [70, 72].
