M501 mini monitor modules provide a 2-wire initiating circuit for normally open contact fire alarm and security devices. The monitor modules are intended for use in intelligent, 2-wire systems where the individual address of each module is selected using rotary decade switches. They can be installed in a single-gang junction box directly behind the monitored unit. Their small size and light weight allows them to be installed without rigid mounting.
