Notifier NZM-100 Zone Interface Monitor Module

Notifier NZM-100(A) is a standard-sized module that monitors and supervises compatible two-wire, 24 volt, smoke detectors on a Style D (Class A) or Style B (Class B) circuit.

The Notifier NZM-100(A) Interface Module is intended for use in intelligent, addressable systems, where the individual address of each module is selected using built-in rotary switches. Besides, this module allows intelligent panels to interface and monitor two-wire conventional smoke detectors. Also, it transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with the module.

In fact, use the NZM-100(A) to monitor a zone of two-wire smoke detectors. Furthermore, the monitored circuit may be wired as an NFPA Style B (Class B) or Style D (Class A) Initiating Device Circuit. A 3.9 K Ohm End-of-Line Resistor terminates the end of the Style B or D circuit. Install ELR across terminals 8 as well as 9 for Style D application.

Each NZM-100(A) uses one of the available module addresses on an SLC loop. Additionally, it responds to regular polls from the control panel and reports its type and the status (open/ normal/short) of its Initiating Device Circuit (IDC). A flashing LED indicates that the module is in communication with the control panel. The LED latches steady on the alarm (subject to current limitations on the loop).
