The interface module can be installed in a single gang junction box directly behind the monitored unit. Its small size and light weight allow it to be installed without rigid mounting. The module is intended for use in addressable, two-wire systems where the individual address of each module is written inside the MCU’s EEPROM by the addressable programmer.

The Interface module allows intelligent panels to interface and monitor 2-wire conventional detectors. The module is addressed through the communication line of an intelligent system. It transmits the status of one zone of 2-wire detectors to the fire alarm control panel. Status conditions are reported as normal, open, or alarm. The interface module supervises the zone of detectors and the connection of the external power supply.
