Firelite MMF-300 Intelligent Monitor Module

The Firelite MMF-300 is a standard-sized module (typically mounts to a 4″ square box) that supervises either a Style D (Class A) as well as Style B (Class B) circuit of dry-contact input devices.

The Firelite MMF-300 Monitor Module intended for use in intelligent, two-wire systems, where the address selected using rotary switches. It provides either a two-wire or four-wire fault-tolerant Initiating Device Circuit (IDC) for normally-open-contact fire alarm and supervisory devices. Also, the module has a panel-controlled LED indicator.

Use to monitor a zone of four-wire smoke detectors, manual fire alarm pull stations, waterflow devices, or other normally open dry-contact alarm activation devices. May also be used to monitor normally-open supervisory devices with special supervisory indication at the control panel. Furthermore, monitored circuit may be wired as an NFPA Style B (Class B) or Style D (Class A) Initiating Device Circuit. Additionally, a 47K Ohm End-of-Line Resistor (provided) terminates the Style B circuit.
