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 4-position rotary selector switch controls the primary operating mode of the siren.

Radio - Also known as Radio Repeat, this function amplifies a radio speaker input for re-broadcast outside the vehicle. No siren tones

or PA operation are available in this mode. The radio must be connected and radio volume adjusted for this mode to function.

Standby - A silent mode that may be overridden anytime with the Manual or Horn or PA operation.

Mech - A simulated mechanical siren tone used anytime.

Yelp -> Phaser -> Wail - This mode provides tones by pressing the Manual push-button to step through the tones. The initial tone is Yelp or optionally may be Wail.

See OPTION SWITCHES section.

Wail - A slower changing tone used on highways.

Yelp - A rapidly changing tone used in congested areas.

Phaser - A very rapidly changing tone used at intersections or in highly congested areas. May be optionally replaced with Two-Tonewhich is two alternating frequencies like a European HI-LO.
