MDF-300(A) Dual Monitor Module
Whitney Even on 06/22/2022
The MDF-300(A) Dual Monitor Module is intended for use in
intelligent, two-wire systems. It provides two independent two-
wire 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 panel-
controlled LED.
NOTE: The MDF-300(A) provides two Style B (Class B) IDC cir-
cuits ONLY. Style D (Class A) IDC circuits are NOT supported in
any application.
MDF-300(A) SPECIFICATIONS
Normal operating voltage range: 15 to 32 VDC.
Maximum current draw: 6.4 mA (LED on).
Average operating current: 750 μA (LED flashing).
Maximum IDC wiring resistance: 1,500 ohms.
Maximum IDC Voltage: 11 Volts.
Maximum IDC Current: 240 μA
EOL resistance: 47K ohms.
Maximum SLC Wiring resistance: 40 Ohms.
Temperature range: 32° to 120°F (0° to 49°C).

Dimensions: 4.5" (11.43 cm) high x 4" (10.16 cm) wide x
2.125" (5.398 cm) deep.
MDF-300(A) AUTOMATIC ADDRESSING
The MDF-300(A) automatically assigns itself to two address-
able points, starting with the original address. For example, if
the MDF-300(A) is set to address "26", then it will automati-
cally assign itself to addresses "26" and "27".
NOTE: "Ones" addresses on the MDF-300(A) are 0, 2, 4, 6, or 8
only. Terminals 6 and 7 use the first address, and terminals 8 and
9 use the second address.
CAUTION:
!
Avoid duplicating addresses on the system.
Installation
MMF-300(A), MMF-302(A), and MDF-300(A) modules mount
directly to a standard 4" (10.16 cm) square, 2.125" (5.398 cm)
deep, electrical box. They may also be mounted to the
SMB500 surface-mount box. Mounting hardware and installa-
tion instructions are provided with each module. All wiring
must conform to applicable local codes, ordinances, and regu-
lations. These modules are intended for power-limited wiring
only.
The MMF-301(A) module is intended to be wired and mounted
without rigid connections inside a standard electrical box. All
wiring must conform to applicable local codes, ordinances, and
regulations.
