MDF-300 Dual Monitor Module The MDF-300(A) Dual Monitor Module is intended for use in intelligent, two-wire systems. It provides two independent twowire initiating device circuits (IDCs) at two separate, consecutive addresses. It is capable of monitoring normally open contact fire alarm and supervisory devices. The module has a single panelcontrolled LED.

The MMF-300 Monitor Module is intended 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 modules in existing systems.

Features

• Built-in type identification automatically identifies this device as a monitor module to the control panel.
• Powered directly by two-wire SLC loop. No additional power 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 latches on steady to indicate alarm.

Addressable Mini-Monitor Module, One Style B (Class B) Initiating Device Circuit for Monitoring N/O contact devices, does not include a polling LED

The MMF-301 monitor 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 MMF-301 is intended for use in intelligent, two-wire systems where the individual address of each module is selected using rotary switches. It provides a two-wire initiating circuit for normally open contact fire alarm and security devices. This module can be used to replace an M301 module in existing systems.

MMF-300(A) is a standard-sized module that supervises either a Style D (Class A) or Style B (Class B) circuit of dry-contact input devices.
