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 auto-
matic timed switching that can interfere with desired operation.
SELECTOR SWITCH
The 6-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. The radio must
be connected and RADIO VOLUME ADJUSTed for this mode to
function.
Horn - A standby (silent) mode that may be overridden anytime with
the Siren push-button to produce a simulated Air-horn tone. Horn
tone may be disabled.
See OPTION SWITCHES section.
Manual – The siren tone rise and fall is manually controlled with
Siren push-button.
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 disabled or optionally replaced
with Two-Tone which is two alternating frequencies like a European HI-LO. See OPTION SWITCHES
section.
SIREN SWITCH
This momentary push-button switch provides Manual tone control and various
tone overrides depending on the Selector switch setting. It can optionally control
Horn Ring Cycler 2 operation in the Horn position if the HRC2 option is selected.
See OPTION SWITCHES section.
With the Dual switch OFF, the following functions are available:
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.
