System Sensor M502M Addressable Interface Module NCA-2 Advanced fire detection algorithms processedThe M502M Interface Module is intended for use in intelligent, two wire systems, where the individual address of each module is selected using the built in rotary decade 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
