Description

The System Sensor M501M is a compact intelligent mini monitor module designed to provide a supervised initiating device circuit (IDC) interface to normally open contact devices such as pull stations, waterflow switches, and security contacts. Intended for use on compatible two-wire signaling line circuit (SLC) systems, the module is addressable via rotary decade switches. Its small size allows installation inside a single-gang junction box or directly behind the monitored device without rigid mounting. The M501M supervises the initiating circuit for open and short conditions and transmits the status to the fire alarm control panel.
