With the selector switch in the Stby position this switch

provides Manual siren tone control, rising when pressed and falling when released. This is used to momentarily alert motorists or in low noise areas.

Optional operation includes replacement of the Phaser tone with Two-Tone or disabling the Phaser tone entirely. These options are selected during installation and may be governed by State or Local laws.

Horn

This momentary push-button switch provides a simulated air-horn tone while pressed. This can be used to supplement the normal vehicle horn and is useful at intersections or in low noise ar- eas. This tone will override all other siren tones.

Microphone

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

siren tone when the button on the side (PTT) is pressed.

 

 

Volume Controls

VOLUME

Volume controls are provided for radio repeat function volume

and public address volume. These should be set when the vehi-

Radio position and the radio volume set to desired level. Set the

PA volume to the maximum level with no feedback (squeal).

 

 

Auxiliary Input

 

 

During installation an auxiliary input may be connected to the horn ring or other switching device. It provides the same operation as pressing the Horn button or optionally the Man/Phsr button.

Cutout

During installation a cutout input may be connected to a door switch. It turns 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 siren control switch or input will restore normal function.
