MMF-301(A) Mini Monitor Module
Whitney Even on 06/22/2022
• Built-in type identification automatically identifies this device
as a monitor module to the panel.
• Powered directly by two-wire SLC loop. No additional power
required.
• High noise (EMF/RFI) immunity.
• Tinned, stripped leads for ease of wiring.
• Direct-dial entry of address: 01 – 159 on MS-9600 series
panels, 01 – 99 on other compatible systems
The MMF-301(A) Mini Monitor Module can be installed in a
single-gang junction directly behind the monitored unit. Its
small size and light weight allow it to be installed without rigid
mounting. The MMF-301(A) 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 initiat-
ing device circuit for normally-open-contact fire alarm devices.
The MMF-301(A) can be used to replace M301(A) modules in
existing systems.
MMF-301(A) APPLICATIONS
Use to monitor a single device or a zone of four-wire smoke
detectors, manual fire alarm pull stations, waterflow devices, or
other normally-open dry-contact devices. May also be used to
monitor normally-open supervisory devices with special super-
visory indication at the control panel. Monitored circuit/device
is wired as an NFPA Style B (Class B) Initiating Device Circuit.
A 47K ohm End-of-Line Resistor (provided) terminates the cir-
cuit.
MMF-301(A) OPERATION
Each MMF-301(A) uses one of the available module
addresses on an SLC loop. It responds to regular polls from
the control panel and reports its type and the status (open/nor-
mal/short) of its Initiating Device Circuit (IDC).

MMF-302(A) Interface Module
• Supports compatible two-wire smoke detectors.
• Supervises IDC wiring and connection of external power
source.
• 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.
• LED latches steady to indicate alarm on command from
control panel.
The MMF-302(A) Interface Module is intended for use in intelli-
gent, addressable systems, where the individual address of
each module is selected using built-in rotary switches. This
module allows intelligent panels to interface and monitor two-
wire conventional smoke detectors. It transmits the status (nor-
mal, open, or alarm) of one full zone of conventional detectors
back to the control panel. All two-wire detectors being moni-
tored must be UL compatible with the module. The MMF-
302(A) can be used to replace M302(A) modules in existing
systems.
MMF-302 (A) APPLICATIONS
Use the MMF-302(A) to monitor a zone of two-wire smoke
detectors. The monitored circuit may be wired as an NFPA
Style B (Class B) or Style D (Class A) Initiating Device Circuit.
A 3.9 K ohm End-of-Line Resistor (provided) terminates the
end of the Style B or D (class B or A) circuit (maximum IDC
loop resistance is 25 ohms). Install ELR across terminals 8
and 9 for Style D application.
MMF-302(A) OPERATION
Each MMF-302(A) uses one of the available module
addresses on an SLC loop. It responds to regular polls from
the control panel and reports its type and the status (open/nor-
mal/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).
MMF-302(A) SPECIFICATIONS
Nominal operating voltage: 15 to 32 VDC.
Maximum current draw: 5.1 mA (LED on).
Maximum IDC wiring resistance: 25 ohms.
Average operating current: 300 μA, 1 communication and 1

EOL resistance: 3.9K ohms.
External supply voltage (between Terminals T3 and T4):
DC voltage: 24 volts power limited. Ripple voltage: 0.1 Vrms
maximum. Current: 90 mA per module maximum.
Temperature range: 32°F to 120°F (0°C to 49°C).
