OPERATION
(Continued)
MANUAL Button - Provides manual control of siren tone rise and fall while in Cycler or Standby. The falling
tone may be stopped immediately by setting the Short Manual option. With siren modes WAIL, YELP, or PHSR
this button toggles between tones.
HORN Button - Produces a simulated Air-Horn tone while pressed. Overrides all siren tones except Radio.
Horn tone may be disabled.
PA - The noise-canceling microphone is used for public address operation and overrides any siren tone when
the button on the side is pressed. Hold the microphone close to your lips for proper operation.
SIRCTRL Input (Optional) - During installation, the siren control input may be connected to the horn ring or
other switching device. Activation of this input will produce Horn tone or other functions depending on the Siren
mode as shown in the table below.
LITCTRL Input (Optional) - During installation, the light control input may be connected to a momentary switch.
Activation of this input will cycle through the Primary button positions, with the Pirmary button overriding if
moved.
CUTOUT Input (Optional) - During Installation, the cutout input may be connected to the vehicle door switch or
other switching device. Activation of this input will turn off any siren tone and remains off when deactivated until
a siren mode is changed.
Timed Override (Optional) - With Siren mode in Wail, Yelp, or Phaser, momentarily pressing the Manual push-
button will toggle between tones overriding the Wail, Yelp, or Phaser tone. With this option selected the unit
automatically goes back to the Wail, Yelp, or Phaser tone after 10 seconds.
Sweep/Intersection Function (Optional) - The Sweep function is an automatic sequence of Yelp, Phaser, and
Horn tones allowing hands free operation. The Intersection function is a more rapid automatic sequence of
Yelp, Phaser, and Horn tones allowing hands free operation through intersections.
With Siren mode in WAIL, YELP, or PHSR, tap the horn ring to start Sweep function. Tap the horn ring again to
start the faster Intersection function. Repeatedly tapping the horn ring will switch between Sweep and Intersec-
tion functions. Tapping the horn ring twice quickly will return to Wail, Yelp, or Phaser tone. Pressing and hold-
ing the horn ring will produce Horn tone until released. Then the siren will return to the Sweep or Intersection
sequence.
