This information is included as a quick reference installation
guide. Refer to the appropriate Fire•Lite control panel installation
manual for detailed system information. If the modules will be
installed in an existing operational system, inform the operator
and local authority that the system will be temporarily out of ser­vice. Disconnect the power to the control panel before installing
the modules. This system contains static sensitive components.
Always ground yourself with a proper wrist strap before handling
any circuits so that static charges are removed from the body. The
module housing should also be grounded.

NOTICE: This manual should be left with the owner/user of this equipment.

GENERAL DESCRIPTION

The CMF-300-6 Six Supervised Control Module is intended for
use in an intelligent alarm system. Each module is intended for
switching applications involving AC or DC which require wiring
supervision. A common SLC input is used for all modules. Each
module has its own address. A pair of rotary code switches is used
to set the address of the first module from 01 to 154. The remain­ing modules are automatically assigned to the next five higher ad­dresses. Provisions are included for disabling a maximum of three
unused modules to release the addresses to be used elsewhere.
Each module also has panel controlled green LED indicators. The
panel can cause the LEDs to blink, latch on, or latch off.

In order to synchronize strobes, horn/strobes, and speaker/
strobes, a SYNC-1 accessory card (sold separately) must be used
with the CMF-300-6. See the SYNC-1 installation manual for de­tails on how to install.

COMPONENTS

Following are descriptions of the CMF-300-6 mounting frame­works. There are two mounting options for CMF-300-6 modules:

• Up to six CMF-300-6 modules can be installed on a CH-6 in
a BB-6 cabinet.

• One or two CMF-300-6 modules can be installed in a BB-2 cabinet.

Chassis

The CH-6 chassis is used to mount CMF-300-6 modules in a BB-6
cabinet. It accommodates up to six CMF-300-6 modules in a single
cabinet row three modules wide and two modules deep.

Figure 1: CH-6 Chassis

with two self-threading screws, which are used to fasten the
chassis to the back wall of the cabinet (see Figure 4).

The BB-2 cabinet comes with the chassis already installed, so

no mounting is necessary.

Figure 3: Typical mounting hole locations

C0235-00

Figure 4: Mounting the CH-6 chassis

The BB-2 cabinet has a built-in chassis that will accommodate
one or two CMF-300-6 modules.

Figure 2: BB-2 Cabinet

The front CMF-300-6 module positions of each chassis are offset
below the rear CMF-300-6 module positions so that all of the sta­tus indicators are visible.

Cabinets

A BB-6 cabinet will house the CH-6 chassis with up to six CMF­300-6 modules installed on it. Refer to cabinet installation docu­ments for dimensions and installation instructions.

The BB-2 cabinet houses one or two CMF-300-6 modules on the
internal chassis that is part of the cabinet. Refer to cabinet instal­lation documents for dimensions and installation instructions.

INSTALLATION STEPS

1. Cabinet Mounting
In a clean, dry area, mount the backbox using the four holes

provided in the back surface of the cabinet (Figure 3).

2. Chassis Installation
The CH-6 chassis is mounted in the BB-6 cabinet. It is shipped

3. Module Installation
There are two methods for installing a module in the rear

position of a chassis. Method one is for installation of a rear
module only, when no module will be installed in front of it.
Refer to Figure 5 for instructions. Method two is for installation
of a rear module when another module will be installed in the
chassis position in front of it. Refer to Figures 6a and 6b for
method two. All necessary screws and standoffs are supplied
with the modules.

Figure 5: Installation of rear module only, method one

Step 1: Insert the bottom of the CMF-300-6 module down into

a rear slot on the chassis.
Step 2: Carefully swing the upper edge of the board back
towards the back of the chassis until it touches
the two standoffs.
Step 3: Align two 4-40 screws with the two standoffs and tighten.
Step 4: Address and wire the modules according to the instruc-

tions in this manual.

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.

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.

Step 1: Insert the bottom edge of the CMF-300-6 module down

into a front slot of the chassis.

Step 2: Carefully swing the upper edge of the board towards

the back of the chassis until it touches the 1

(31.75mm) standoffs installed on the rear module.
Step 3: Align two 4-40 screws with the two standoffs and tighten.
Step 4: Address and wire the mod ules acco rding to the

instructions in this manual.

WIRING

NOTE: All wiring must conform to applicable local codes, ordi­nances, 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 1/4˝ 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 avail­able. 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

/4˝

NOTE: In Class A operation, placing the small shunt on “disable
3˝ will disable all three addresses. Placing the small shunt on “dis­able 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

Figure 7:

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

C0227-00

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.
