YELP
TONE3 R
YELP (Yelp Tone) - When the rotary knob is in the YELP
position, a fast, rise and fall tone is produced. A single tap on
the MAN switch changes the siren tone to TONE3. A second
tap, and the siren returns to a YELP tone.
TONE3 (Piercer TM Tone / in Default Configuration) - When
the rotary knob is in the TONE3 position, an extremely fast, rise
and fall tone is produced. Pressing on the MAN switch changes
the siren tone to a simulated air horn tone for as long as the
button is pressed. Releasing the button causes the siren to
return to the Piercer tone.
VOLUME KNOB - The volume knob controls the volume of
public address function. Volume is increased by rotating the
knob in a clockwise direction and decreased by rotating the
volume knob in a counter-clockwise direction. This knob has no
effect on any siren tones produced.
LIGHTS-SIREN / SIREN SWITCH - The lights-siren/siren
switch provides the operator with the ability to activate any lights
that have been connected to the WPA circuit. In the siren
position, siren control operates as described in this manual.
Moving the switch to the lights-siren position not only allows
siren control, but activates any lights connected to the control
wires indicated on page 3.
AIRHORN OVERRIDE / MANUAL SIREN SWITCH - The
Airhorn override switch will activate the simulated airhorn tone
when pressed and will terminate upon release. The airhorn will
override all of the WPA control head functions. The manual
siren switch activates any of the simulated siren tones
determined by the rotary switch position noted above.
Section IV: Operating the WPA TM or BETA2™
MICROPHONE
Pressing the microphone button will allow you to broadcast
public address over the siren loudspeaker regardless of the
rotary switch position. NOTE: This will override all other siren
functions.
ROTARY SWITCH
The Rotary Knob controls the siren and PA (Public Address)
functions of the WPA / BETA2 There are 8 positions that may be
selected including “Off” (Fig. 10). Functions are outlined below:
RAD (Radio Repeat) - When the rotary knob is in the RAD
position, any signal that is received by the vehicle’s two-way
radio will be simultaneously broadcast over the vehicle’s
loudspeaker (The remote amplifier must be connected to the
two-way radio speaker. See the WPA / BETA remote amplifier
manual for the proper wiring and operation).
PA (Public Address) - When the rotary knob is in the PA
position, public address functions are operational. Messages
may be broadcast over the vehicle’s loudspeaker via the WPA /
BETA2 microphone. The volume level of PA transmissions is
controlled by the volume knob. If the MAN / AIRHORN button is
pressed while the rotary knob is in this position, an air horn
siren tone will be generated by your vehicle’s loudspeaker. This
tone is generated until the horn ring button is released.
MAN (Manual Siren) - When the rotary knob is in the MAN
position, pressing the MAN switch generates a tone that rises in
pitch to a pre-set level. This tone is generated for as long as the
MAN switch is pressed.
HF (Hands Free Operation) - When the rotary knob is in the
HF position, the siren functions of the WPA / BETA2 are placed
in a standby mode. Siren tones are activated by a single ‘tap’ of
the MAN switch. The first tap produces a Wail tone (a steady,
rise and fall tone). A second tap produces a Yelp tone (a fast,
rise and fall tone). A third tap produces a Piercer
TM tone (an
extremely fast, rise and fall tone). The next tap returns the siren
to a Wail tone and the cycle repeats itself. Two quick,
successive taps will stop the siren.
WAIL (Wail Tone) - When the rotary knob is in the WAIL
position, a steady, rise and fall tone is produced. A single tap on
the MAN switch changes the siren tone to a Yelp pattern (a fast,
rise and fall tone). A second tap, and the siren returns to a Wail
tone.
