FZM-1 (A) Interface Module is intended for us in intelligent, addressable systems, where the individual address of each module is selected using built-in rotary switches. This module allows intelligents panels to interface an monitor two-wire conventional smoke detectors. It transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the contraol panel. All two-wire detectors being monitored must be UL compatible with the module. The FZM-1(A) can be used to replace MMX-2(A) modules in existing systems
Application: Use 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 3.9K 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.
Specification: Nominal operating voltage: 15 to 32VDC Maximum current draw: 5.1mA (LED on). Maximum IDC wiring resistance: 25 Ohms EOL resistance: 3.9 Ohms
