GENERAL
Four different monitor modules are available for Fire•Lite Alarm’s
MS-9200 and MS-9600 intelligent fire alarm control panels
to suit a variety of applications. Monitor modules are used to
supervise a circuit of dry-contact input devices, such as conventional heat detectors and pull stations, or monitor and
power a circuit of two-wire smoke detectors (MMF-302).
MMF-300 (Replaces M300) — The MMF-300 Monitor Module is a standard-sized module (typically mounts to a
4" [101.6 mm] square box) that supervises either a Class A
(Style D) or Class B (Style B) circuit of dry-contact input devices.
MMF-300 MONITOR MODULE
- 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 Decade 01 – 99 (MS-9200) and 01-159 (MS-9600) entry of address.
- LED flashes green during normal operation and latches on steady red to indicate alarm
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 Class A or Class B faulttolerant Initiating Device Circuit (IDC) for normally-open-contact fire alarm and supervisory devices. The module has a
panel-controlled LED indicator. The MMF-300 can be used
to replace M300 modules in existing systems.
MMF-300 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 normallyopen 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 D) 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. Maximum IDC resistance is
1,500 ohms.
MMF-300 Operation
Each MMF-300 uses one of
99 (MS-9200) or 159 (MS-9600) available module addresses
on an SLC loop. It responds to regular polls from the control
panel and reports its type and the status (open/normal/short)
of its Initiating Device Circuit (IDC). A flashing LED indicates
that the module is in communication with the control panel.
The LED latches steady on alarm (subject to current limitations on the loop).
INSTALLATION
MMF-300, MMF-302 and MDF-300 modules mount directly
to a standard 4" (101.6 mm) square, 2.125" (53.975 mm)
deep, electrical box. They may also be mounted to the
SMB500 surface-mount box. Mounting hardware and installation instructions are provided with each module. All wiring
must conform to applicable local codes, ordinances, and regulations. These modules are intended for power-limited wiring only.
