The communicator cabinet may be either semi-flush or

surface mounted. The door is removable during the installa-

tion period by opening and lifting off the hinges. The

cabinet mounts using two key slots and two additional 0.25"

diameter holes located in the backbox. The keyslots are

located at the top of the backbox and the two securing holes

at the bottom.

Carefully unpack the system and check for shipping damage. Mount the cabinet in a clean, dry, vibration-free

area where extreme temperatures are not encountered. The area should be readily accessible with sufficient room

to easily install and maintain the panel. Locate the top of the cabinet approximately five feet above the floor with

the hinge mounting on the left. Determine the number of conductors required for the devices to be installed.

Sufficient knockouts are provided for wiring convenience. Select the appropriate knockout(s) and pull the

required conductors into the box. Note that there are no knockouts on the left (hinged) side of the cabinet. All

wiring should be in accordance with the National and/or Local codes for fire alarm systems.

Backbox Mounting

• Open the door and lift the door off the pin hinges

• Mark and predrill holes for the top two keyhole mount-

ing bolts using the dimensions shown in Figure 2

• Install two upper fasteners in the wall with the screw

heads protruding

• Using the upper 'keyholes', temporarily mount the

backbox over the two screws

• Mark the lower two holes, remove the backbox from

the wall and drill the lower two holes in the wall

• Before mounting the backbox to the wall, install the

supplied transformer in the backbox by sliding the bot-

tom transformer flange into the lower transformer

mounting slot. Position the hole in the top transformer

flange over the transformer mounting stud. Refer to

Figure 1 for the location of the slot and stud

• Secure the transformer with the supplied nut and

attached washer

• Mount the backbox to the keyhole mounting bolts,

install and tighten the remaining fasteners

Main Circuit Board Mounting

• When the location is clean and free of construction dust or other potential contaminants, install the main PC

board by installing the four supplied standoffs on the four main circuit board mounting studs located in the

backbox. Refer to Figure 2

• Position the main circuit board’s four corner mounting holes over the four standoffs just installed. Be certain

to observe the proper ESD (Electro Static Discharge) precautions to prevent damage to the static sensitive

circuits. This includes, but is not limited to, use of a wrist strap

• Secure the main circuit board to the standoffs with the four supplied screws and attached washers

• Plug the transformer connector into the main circuit board connector J4. The connector is keyed and can only

be plugged-in one way.

• When wiring is completed, install the door on the backbox pin hinges and the window bezel in the door
