VOLUME CONTROLS

RADIO REPEAT VOLUME

The radio repeat volume is recessed on the

front face of the amplifier next to the

communication jack. 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. Adjust the siren’s rotary

selector switch into the

RADIO position. Insert a small, flat blade screwdriver into the RADIO volume

adjustment port. Turn clockwise direction to increase the sound level.

PA VOLUME:

The PA volume control is provided for public address

volume. This is located in the upper right hand corner of

the control head. It should be set when the vehicle is

parked. Set the PA volume to the maximum level with

no feedback (squeal).

MICROPHONE

The attached noise-canceling microphone is used for public address operation and

overrides any siren tone when it’s push-to-talk (button on the side) is pressed.

AUXILIARY INPUT

During installation an auxiliary input may be connected to the vehicle horn ring or

other switching device. It provides the same operation as pressing the Horn button

or optionally (via internal jumpers) the Manual (MAN) push-button.

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

hand corner of the control head. These LED’s will only

turn on while a tone is trying to be generated. Status of the

speakers is indicated as follows:

Steady - Speaker is connected and operating properly.

Flashing - There is an electrical short in the speaker or

wires to the speaker.

Off - 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
