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.
Power/PA Knob
The
PA
knob is located in the upper right hand corner of the
front face. It has two functions:
ON/OFF
- This knob turns the siren on and off. While in
the OFF position none of the siren functions
will work. Also, the vehicle horn will function
normally, if connected properly.
PA Volume Control
- This knob also provides you the ability to
adjust the public address volume. It should
be set when the vehicle is parked. Typically
you should set the PA volume to the
maximum possible level with no feedback
(squeal).
Selector Switch
The rotary selector switch controls the primary operating function of the siren.
PHSR
- Ultra-fast changing tone used for maximum attention.
YELP
- A rapidly changing tone used in congested areas.
WAIL
- A slower changing tone used on highways.
HF
- Hands Free - A silent standby mode also known as Horn Ring Cycler.
Allows the user to cycle through the tones programmed for the WAIL,
YELP, PHSR, and OFF by repeatedly pressing the horn or other switch
connected to the AUX input. Changing the rotary knob to any other
mode will resume normal siren operation.
MAN
- A silent standby mode that allows push-button Manual, push-button Horn,
and Public Address operation. The siren output winds down when the
MAN button is released.
ALERT
- A silent standby mode that allows push-button Manual, push-button Horn
and Public Address operation. The siren output terminates immediately
when the MAN button is released.
RADIO
- Also known as Radio Repeat, this function amplifies a
two-way
radio
speaker input for re-broadcast outside the vehicle. The PA remains
functional, but no siren tones are available in this position.
