Connecting to a Remote Control Head:
(Optional)
This unit may be connected to an existing control head,
such as the Whelen PCDS-9 or equivalent. This is an
optional connection that enables the WAIL tone to be
activated through the use of a PCDS-9 button or switch.
If this connection is not chosen, cut the VIOLET wire and
cap it to prevent accidental grounding of the wire.
OPERATING THE CONTROLS:
PA VOLUME (MIC)
If your model uses a potentiometer, locate the
MIC adjustment port as shown. With the
vehicle in an enclosed area, turn the siren on
and speak into the microphone. While
speaking, insert the screwdriver and turn
clockwise to increase the volume. Continue to
increase the PA volume until audio feedback
occurs. Turn the screwdriver counter-clock
wise to eliminate feedback. For models with a
PA Volume knob, follow the same procedure
using the knob.
POWER
ON
POWER SWITCH
This switch has two positions: Down (Off) and Up
(On). When this switch is Off, the unit will not
function. When the switch is On, the siren is
functional and may be activated at the operator’s
discretion. This switch also activates control head
backlighting.
NOTE:
If the unit is connected to the
vehicle’s horn ring circuit, the vehicle horn is
disabled when the power switch is in the ON
position.
ROTARY SWITCH
The rotary knob controls the siren functions.
There are 7 positions that may be selected. Each
position and its function is outlined under “Rotary
Switch Operations.”
MAN BUTTON
The Manual button generates a variety of tones,
depending on what position the rotary knob is in.
For further explanation of this button’s function,
refer to “Rotary Switch Operations.”
RADIO REPEAT VOLUME (RAD)
Locate the Radio Repeat adjustment port as
shown. Set the volume level of the vehicle’s two-
way radio to its normal operating volume. Turn the
rotary knob to RAD to activate Radio Repeat.
Insert the screwdriver in the Radio Repeat
adjustment port and turn clockwise to increase
the volume.
