OPERATION

Sound Hazard - Sound level from siren speaker (>120dBA @ 10 feet) may cause hearing damage. Do not operate siren without adequate hearing protection for you and anyone in immediate vicinity. (Ref. OSHA 1910.95 for occupational noise exposure guidelines)

GENERAL

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

SIREN SECTION CONTROLS

Siren Control Switches

Two 3-position rocker switches control the pri-

mary operating function of the siren.
On - Applies power to the siren system for opera-
	YELP		ON
tion independent of light control system. It also
turns on backlighting for night use.	STBY		OFF
Off - Turns off power to the siren section.	WAIL		RAD
Radio - Also known as Radio Repeat, this func-
tion amplifies a radio speaker input for re-
broadcast outside the vehicle. No siren tones or
PA operation are available in this position.
Yelp - A rapidly changing tone used in congested areas.
Stby - A silent mode that allows Manual, Horn and Public Address operation.
Wail - A slower changing tone used on highways.
Man/Phsr
This momentary push-button switch provides a very
rapid changing tone (Phaser) when the selector switch
is in the Yelp or Wail positions. This tone is used at
intersections and very highly congested areas. Press-
ing the button once changes to the Phaser tone and		MAN/PHSR	HORN
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 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-
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	RAD	PA
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.
