Fire-Lite MMF-300 Series Addressable Monitor Module (Replaces M300)

Description

The MMF-300 Addressable Monitor Module is for use in intelligent, two-wire systems, where the individual address of each module is selected using the built-in 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. The module has a panel-controlled LED indicator. The MMF-300(A) can be used to replace M300(A) modules in existing systems.

MMF-300 is a standard-sized module (typically mounts to a 4″ [10.16 cm] square box) that supervises either a Style D (Class A) or Style B (Class B) circuit of dry-contact input devices.

MMF-300(A) Addressable Monitor Module Applications

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. Monitored circuit may be wired as an NFPA Style B (Class B) or Style D (Class A) Initiating Device Circuit. A 47K Ohm End-of-Line Resistor (provided) terminates the Style B circuit. No resistor is required for supervision of the Style D circuit.

Main Features

• Built-in type ID automatically identifies this device as a monitor module to the control panel.
• Powered directly by two-wire SLC loop. No additional power is required.
• High noise (EMF/RFI) immunity.
• SEMS screws with clamping plates for ease of wiring.
• Direct-dial entry of address: 01 – 159 on MS-9600 series panels, 01 – 99 on other compatible systems.
• LED flashes during normal operation and stays on steady to indicate alarm.
