and B operation, DO NOT set the lowest address above 154, as the
other modules will be assigned to nonexistent addresses.
NOTE:
Some panels support extended addressing. In order to set
the module above address 99 on compatible systems, carefully
remove the stop on the upper rotary switch (see Figure 7). If the
panel does not support extended addressing, do not set the lowest
address above 94.
4. A shunt is provided to disable a maximum of three unused
modules (see Figure 8). Modules are disabled from the highest
address and work downward. If two modules are disabled, the
lowest four addresses will be functional, while the highest two
will be disabled. For example, if the shunt for Address Disable
is placed on “two” and the base address switch is set to 28,
the modules will be assigned to 28, 29, 30 and 31, disabling
the highest two positions.
NOTE:
In Class A operation, placing the small shunt on “disable
3˝ will disable all three addresses. Placing the small shunt on “dis-
able 2˝ will disable two out of the three addresses. For example,
if the address switch is set to 28 and the small shunt is placed on
“disable 2˝, addresses 30 and 32 will be disabled while address
28 will be enabled.
5. There is a short circuit protection option for each address. The
board is shipped with short circuit protection disabled for each
address represented by six large shunts on the “Disable Short
Circuit Protection” area. To enable short circuit protection for
an address, remove the corresponding pins from the “Disable
Short Circuit Protection” area. When enabled, the module will
not switch power supply if a short circuit condition exists on a
notification appliance circuit.
NOTE:
Power must not be applied to the unit when changing
functionality of the shunts.
NOTE:
Place unused shunts on single pin to store on board for
future use.
NOTE:
The power supply monitoring
feature is currently not supported.
NOTE:
SLC wiring is the top terminal
block, notification appliance/power
supply is the bottom.
NOTE:
Whether in Class B or Class
A wiring, power supply monitoring
and short circuit protection must be
enabled on the NAC circuits that are sharing a power supply.
NOTE:
Short circuit protection can only be disabled if a power
supply is not being shared by multiple NACs.

The steps in Figures 6a and 6b describe and illustrate module in-
stallation when the rear chassis position and the position in front
of it will be filled. Front position installation is possible only if the
rear position is filled with a module.

Step 1: Insert the bottom edge of the CMF-300-6 module down
into a rear slot of the chassis.
Step 2: Carefully swing the upper edge of the board towards
the back of the chassis until it touches the short stand
off attached to the chassis.
Step 3: Align the long standoff with the short standoff and tighten.

WIRING
NOTE:
All wiring must conform to applicable local codes, ordi-
nances, and regulations.
1. Install module wiring in accordance with the job drawings and
appropriate wiring diagrams.
2. All wiring to the CMF-300-6 is done via terminal blocks. In
order to properly make electrical connections strip approxi-
mately

˝ of insulation from the end of wire, sliding the bare
end of the wire under the clamping plate screw.
3. Set the address on the modules per the job drawing. Use the
rotary code switches to set the address of the first module (be-
tween 01 and 154).
In Class B operation, the remaining modules are automatically
assigned to the next five higher addresses. For example, if the
base address switch is set to 28, the next five modules will be
addressed to 29, 30, 31, 32, and 33.
In Class A operation, a maximum of three Class A circuits are avail-
able. For example, if the base address switch is set to 28, 30 and 32
will be automatically assigned to the modules while 29, 31 and 33
are available to be used for other modules on the SLC. For Class A
