INTRODUCTION
Overview
The ACT (Always Clear Talking) intercom system from FRC has updated noise
cancellation circuitry that essentially eliminates acoustical background noise. The
compact control module is separate from the speaker box to provide installation
exibility. Multiple mounting options that only require a two-wire connection between
stations, and hands-free remote operation make this intercom especially useful for
aerial applications. A high level output signal ensures high quality sound even when
the wires are routed through the aerial turntable.
The intercom system is designed to meet rescue and re service requirements for
a voice communications system. It is weather-resistant and specically designed for
outside use on re service apparatus.
The PTT (Push-To-Talk) station is always in receive mode. The PTT button must
be pressed to transmit.
The hands free station is always in transmit mode. To talk on the intercom the
operator speaks and the intercom transmits. It will be in receive mode when another
station is transmitting.
Since March 2012 all ACT intercom control modules have included a program that
allows for setting the volume level at power-up. Two modes are available:
Power-up at the last used volume setting;
Power-up at a pre-set volume.

INSTALLATION
Install Control Module
The control module is mounted with a bracket or to the surface with a panel cutout
for the connector.
Bracket Mount
Note: The mounting bracket can be removed by unscrewing the adjustment
knobs at the side of the control module.
1. Measure and mark mounting location for control module bracket. Refer to
Figure 1 for layout and dimensions.
2. Drill two mounting holes (clearance or tapped) for mounting 10-32 hardware.
3. Place mounting bracket in position and secure with two screws.
4. If bracket was removed from module, place module in position and install
rubber bushings and mounting knobs.
5. Connect the cables and wiring. Provide enough slack in the cable(s) for the
control module to be adjusted as needed. (Refer to Wiring Section).
Surface Mount
1. Measure and mark mounting location for control module panel cutout and
mounting screw holes. Make sure there is clearance behind the panel for the
connector and wiring before cutting holes. Refer to Figure 1 for layout and
dimensions.
2. Cut out a 1 3/8" wide by 2 3/8" high hole for the connector to t through and
drill two holes (clearance or tapped) for 10-32 mounting screws.
3. Place control module in position and secure with two screws.
4. Connect the cables and wires. (Refer to Wiring Section).

Install Speaker Box
The speaker box is mounted with a bracket or to the surface with a feed through
hole for the cable.
Bracket Mount
Note: The mounting bracket can be removed by unscrewing the adjustment
knobs at the side of the control module.
1. Measure and mark mounting location for speaker box bracket. Refer to Figure
2 for layout and dimensions.
2. Drill four mounting holes (clearance or tapped) for mounting 10-32 hardware.
3. Place mounting bracket in position and secure with four screws.
4. If bracket was removed from box, place box in position and install rubber
bushings and mounting knobs.
5. Connect the cable. Provide enough slack in the cable for the speaker box to be
adjusted as needed. (Refer to Wiring Section).
Surface Mount
Note: At the rear of the box there are four 10-32 blind tapped holes to accept
the mounting screws (1/2 to 5/8 inch deep). Ensure that the mounting
screws do not bottom out in the hole.
1. Measure and mark mounting location for speaker box cable hole and mounting
screw holes. Make sure there is clearance behind the panel before drilling holes.
Refer to Figure 2 for layout and dimensions.
2. Drill a 3/4" hole for the cable and four clearance holes for 10-32 mounting
screws.
3. Place speaker box in position and secure with four screws.
4. Connect the cable to the control module. (Refer to Wiring Section).

OPERATION
The Push-To-Talk modules are always in receive mode. The Push-To-Talk button
must be pressed to put the module into transmit mode.
The hands free module is always in transmit mode. To talk on the intercom the
operator speaks and the intercom transmits. It is in receive mode when another module
is transmitting.
Two-Way System
The system includes two control modules with a Push-To-Talk button or one
control module with a Push-To-Talk button and one control module that is hands free.
Three-Way System
The system includes three control modules with a Push-To-Talk button or two
control module with a Push-To-Talk button and one control module that is hands free.
Operational Check
1. Turn on DC power to intercom.
2. Press the Push-To-Talk button to put control module in transmit mode and
speak toward the control module microphone.
Result: Voice is heard over speaker(s) connected to other control modules.
(Adjust the volume level buttons at each module for receive level.)
3. Repeat step 2 at each control module. If a hands free module is installed speak
toward the control module microphone and it is in transmit mode.
Programmable Power-Up Volume Level
ACT intercom control modules include a program that allows for setting the volume
level at power-up. Two modes are available:
Power-Up at the Last Used Volume Setting
1. Press and hold the volume increase button until the top LED ashes. Release
the button and wait 15 seconds.
Result: The volume drops to 50% level; the module sets to the last used volume
level on power-up.
Power-Up at a Pre-Set Volume.
1. Press and hold the volume decrease button until the bottom LED ashes.
Release the button.
2. Press the increase button and set to desired level. Release the button and wait
until the highest LED ashes.
Result: The module sets to this volume level on power-up.
