FireLite MMF-302 Address 2-Wire Monitor Module


Our Price : $132.95

Product Code: MMF-302


The MMF-302 Interface Module 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) 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. The MMF-302 has a panel-controlled LED indicator and can be used to replace M302 modules in existing systems.
