Auxiliary Input Polarity - The auxiliary input is normally activated by connecting to positive. To
activate by connecting to ground cut the two jumper resistors labeled "AUX P".
Cutout Input Polarity - The cutout input is normally activated by connecting to positive. To activate by connecting to ground cut the two jumper resistors labeled "CUT P".
Two-Tone - Two-Tone can replace Phaser by cutting the jumper resistor labeled "T-T".
Phaser Disable - The Phaser function can be completely disabled by cutting the jumper resistor
labeled "PHSR".
Horn Disable - The Horn function can be disabled by
cutting the trace on the back of the board at the location
designated "cut to disable horn".
Horn Ring Cycler option (HRC) - This option allows
selection of Wail, Yelp, Phaser and Standby by repeatedly pressing horn ring or other switch connected to the
C u t to →

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 rotary selector switch controls the primary operating function of the siren.
Yelp - A rapidly changing tone used in congested
areas.
Wail - A slower changing tone used on highways.
Stby - A silent mode that allows Manual, Horn and
Public Address operation.
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 position.
YELP
WAIL
STBY
RADIO
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. Pressing the button once changes to the Phaser tone and 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
MAN/PHSR
HORN
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 areas.
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 is pressed.
VOLUME CONTROLS
Volume controls are provided for radio repeat function volume
and public address volume. These should be set when the vehicle is parked. Set the RAD volume with the selector switch in the
Radio position and the radio volume set to desired level. Set the
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 switch or input will restore normal function.
HORN RING CYCLER (Optional)
During installation, the auxiliary input may be connected to the horn ring or other switching device,
and the HRC option programmed. With the Selector Switch set to the STBY position, the horn
ring can be pressed repeatedly to select the Wail, Yelp, Phaser and Standby tones or modes in
succession. Operating any other switch resumes normal operation. Please note that this option
disables Phaser selection in the Wail or Yelp selector switch positions.

SERVICE
This unit is designed to provide years of reliable service under even the worst conditions. Many
times there may appear to be a problem with the unit when the true problem is in the speaker(s)
or improper installation. The following chart shows typical symptoms and possible causes.
A blown internal fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead
is shorted the internal fuse will blow before the unit is damaged. Disconnect the SPKR leads and
replace the fuse. If the siren emits a sound when in the Yelp position it is OK. Check the speaker
(s) or leads for possible shorting.
