Description

The NC-100 Notifier (A) Addressable Control Module provides NOTIFIER’s FireWarden Series intelligent control panels a supervised Class B (Style Y) of Class A (Style Z) circuit for Notification Appliances (horns, strobes, etc.). Addressability allows the NC-100(A) to be activated, either manually or through panel programming, on a select (zone or area of coverage) basis. Each NC-100(A) uses one of the module addresses on a SLC loop. It responds to regular polls from the control panel and reports its type and status, including the open/normal/short status of its Notification Appliance Circuit (NAC). The LED blinks with each poll received. On command, it activates its internal relay. The NC-100(A) supervises Class B (Style Y) or Class A (Style Z) notification or control circuits. Upon code command from the panel, the NC-100(A) will disconnect the supervision and connect the external power supply in the proper polarity across the load device. The disconnection of the supervision provides a positive indication to the panel that the control relay actually turned ON. The external power supply is always relay-isolated from the communication loop so that a trouble condition on the external power supply will never interfere with the rest of the system.
