VOLUME CONTROLS
Radio Repeat Volume
The radio repeat volume is located
within the rear access cover of the
amplifier. This should be set when
the vehicle is parked. First set the
volume level of the vehicle’s two-way radio to its normal operating volume. Press the
RADIO button of siren controls. Using a small flat blade screwdriver, adjust the
potentiometer as desired.
PA Volume
The PA volume control is provided for public address
volume. This is in the bottom left corner of the
control head. Insert a small, flat blade screwdriver
into the PA volume adjustment port. Turn counter-
clockwise direction to increase the sound level.
MICROPHONE
The integrated noise-canceling microphone is used for public address operation
and overrides any siren tone when its push-to-talk (button on the side) is pressed.
AUXILIARY INPUT
During installation the vehicle horn ring or other switching device may be
connected to the auxiliary input (AUX/Green wire). This will provide the same
operation as pressing the HORN button. NOTE: This may also be changed to
provide the same operation as the MAN button instead of the HORN button
.
(See Light Control Option Jumpers on pages 7-8)
PARK KILL (CUTOUT)
During installation, the Park Kill input may be connected to a door
switch. It will automatically turn off any siren tone when the door is
opened. The siren tone will continue to be cut off even when the door is
closed. Changing any switch or input will restore normal function.
SPEAKER DIAGNOSTICS
There are two diagnostic LED’s located in the lower left portion of
the remote head controller. These LED’s will only turn on while a tone is
trying to be generated. Status of the speakers are indicated as follows:
Steady

Flashing
- There is an electrical short in the speaker or wires to the
speaker.

- No speaker is connected, or
- The siren is not activated to output a tone to the speaker, or
- The speaker or wire connection is loose or is electrically open
