D. Mounting.
The selection of the mounting location for the device, its controls, and the routing of
the wiring are to be accomplished under the direction of the facilities and the safety
engineer.
The panel mount intercom is designed to be mounted behind a customer-supplied panel.
1. Cut an opening and drill the four (4) mounting holes in the customer-supplied panel.
Refer to Figures 1 and 6.
2. Carefully insert the panel mount intercom into the customer-supplied panel.
3. Secure the panel mount intercom by installing screws in the four (4) mounting holes.
The four mounting holes are 0.191" in diameter and will accept a #8 mounting screw.
Hardware for mounting the intercom to the surface is left up to the installer.
Refer to instruction sheet 2561543, if necessary, for mounting the speaker.
E. Electrical Connections.
Connect the power wires labeled
“PWR +” and “PWR -” on the panel mount intercom
to a nearby power source. On 120/240VAC models, the green/yellow wire labeled
“EGND” should be connected to earth ground. Connect the audio wires labeled “SPK”
(white/brown) and “COM” (white) from the intercom to the local speaker/microphone.
Models with the
“-M44” option have an extra pair of audio wires labeled “REM SPK”
(black) and
“COM” (white) that should be connected to a remote speaker. Connect
the audio wires labeled
“AUD” (black or green) and “COM” (white) on the panel mount
intercom to the same color audio wires on another intercom in the system. Audio
wires should be sized properly by a licensed installation electrician for your specified
application.
“C” and “D” models have a control line labeled “CTRL” (black). The
control line on a
“C” model (Primary mode) connects to the control line on a “D” model
(Secondary mode). Refer to Figures 2 through 5 for typical connections and additional
wiring information.
Optional: A 1K, 1W resistor is included in a kit with each intercom. Installing the
resistor across the audio lines helps to reduce noise in certain environments. Only one
resistor needs to be installed on the lines for any system installation.
F. Service.
Federal Signal will service your equipment or provide technical assistance with any
problems that cannot be handled locally.
