FZM-1

Interface Module for use in Intelligent, addressable systems

• Supports compatible two-wire smoke detectors.
• Supervises IDC wiring and connection of external power source.
• High noise (EMF/RFI) immunity.
• SEMS screws with clamping plates for ease of wiring.
• Direct-dial entry of addresses (01-159).
• LED flashes during normal operation (this is a programmable option).
• LED latches steady to indicate alarm on command from control panel.

The FZM-1 Interface Module (made by Notifier for integration with Multicom ICS systems) is intended for use in intelligent, addressable systems, where the individual address of each module is selected using built-in rotary switches. This module allows intelligent panels to interface and monitor two-wire conventional smoke detectors. It transmits the status (normal, open, or alarm) or one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with the module. The FZM-1 has a panel-controlled LED indicator and can be used to replace MMX-2 modules in existing systems.

Applications

Use the FZM-1 to monitor a zone of two-wire smoke detectors. 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 (provided) terminates the end of the Style B or D (class B or A) circuit (maximum IDC loop resistance is 25 ohms). Install ELR across terminals 8 and 9 for Style D application.

Operation

Each FZM-1 uses one of 159 available module addresses on an SLC loop. 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 alarm (subject to current limitations on the loop).
