Electrical connections to the unit are made using a
removable terminal block plug located on the back. A
label on the unit identifies the terminal function. You
should install the connector on the unit before wiring. If
the unit needs service the connector can be easily
removed without unwiring the connector.
The power supply of the unit must be capable of
delivering peak currents up to 50 amps for adequate
short circuit protection and reliable operation. The
preferred source is directly at the vehicle battery. The
unit is internally fused.
Attach leads by stripping 3/8", inserting into connector
and clamp by tightening screw. Make sure the screw is
tight and the wire can't be pulled out. Failure to
adequately tighten the screw can result in improper
operation or burning the connector and wire.
Wire Size and Termination - The diagram shows the
minimum wire size used for each connection, along with
recommended lead color. If the wire is longer than 10 ft.
use the next larger wire size. Use only high quality
crimp connectors for installation on the vehicle.

OPERATION
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.
(Ref. OSHA 1910.95 for occupational noise exposure guidelines)
The OFF/ON Rocker Power Switch controls the siren power. The siren may be left on any time the vehicle is in
operation. The power should be turned off when vehicle is not being used to conserve battery power.
The Rotary Function Switch selects various operating modes. These modes are as follows:
Yelp:
The siren produces a moderate warble tone. This mode may be used in
lightly congested areas.
Wail:
The siren produces a normal rise-fall tone pattern. This mode may be
used on highways or areas with constant traffic flow.
YELP
WAIL
STBY
RADIO
Standby:
A silent mode that allows Manual, Horn and Public Address operation.
Radio:
This mode reproduces, or repeats, the output of a radio. The radio must be connected and RADIO
VOLUME on the face adjusted. No siren tones or PA operation are available in this position.
Manual /
Phaser:
With the mode switch in the Standby position this push-button switch
provides Manual siren tone control, rising when pressed and falling when
released. When the mode switch is in the Wail position, the push button
overrides with Yelp tone. When the mode switch is in the Yelp position,
MAN/PHSR
HORN
the push-button overrides with Phaser tone. This tone is a very fast
warble tone used at intersections or in highly congested areas. Pressing
the button once changes to the override tone and pressing again changes
the tone back to Yelp or Wail. Optional operation includes replacement of the Phaser tone with Two-Tone
or disabling the Phaser tone entirely
Horn:
This 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.
PA:
Pressing the microphone button in any mode except Radio changes the unit to PA (Public Address). The
siren mode resumes when the button is released. Adjust the PA Volume and hold the microphone close
to your lips for proper operation.
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).
VOLUME

PA
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 siren control 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 mode switch set to the Standby 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), controlled devices, 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 this fuse
will blow before the unit is damaged. Disconnect the SPKR leads and replace the fuse. If the unit itself emits a low
level sound when in the Yelp position it is OK. Check the speaker(s) or leads for possible shorting.
