OPERATION

GENERAL

This unit is designed for easy operation under the stress associated with high-speed pursuit. Most siren functions are accessible with one simple motion without repetitive activation of switches or automatic timed switching that can interfere with desired operation.

SELECTOR SWITCH

The rotary selector switch controls the primary oper- ating function of the siren.

Yelp - A rapidly changing tone used in congested areas.

Wail - A slower changing tone used on highways. Stby - A silent mode that allows Manual, Horn and Public Address operation.

Radio - Also known as Radio Repeat, this function amplifies a radio speaker input for re-broadcast out- side the vehicle. No siren tones or PA operation are available in this position.

YELP

WAIL STBY

RADIO

MAN/PHSR

This momentary push-button switch provides a very rapid changing tone (Phaser) when the selec- tor switch is in the Yelp or Wail positions. This tone is used at intersections and very highly con- gested areas. Pressing the button once changes to the Phaser tone and pressing again changes the tone back to Yelp or Wail.

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 en- MAN/PHSR HORN tirely. 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 areas. 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 is pressed.

VOLUME CONTROLS

Volume controls are provided for radio repeat function volume and public address volume. These should be set when the vehi- cle is parked. Set the RAD volume with the selector switch in the 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 switch or input will restore normal function.

HORN RING CYCLER (Optional)

During installation, the auxiliary input may be connected to the horn ring or other switching device, and the HRC option programmed. With the Selector Switch set to the STBY position, the horn ring can be pressed repeatedly to select the Wail, Yelp, Phaser and Standby tones or modes in succession. Operating any other switch resumes normal operation. Please note that this option disables Phaser selection in the Wail or Yelp selector switch positions.
