CAUTION
Loud siren noise can cause
hearing damage and/or loss.
Refer to OSHA Section 1910.95 prior
to putting ANY siren into service!

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™
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 vehicle’s steering wheel horn ring button (if the vehicle’s horn
has been wired to the BETA1), 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. Please note that the BETA1 microphone
will override the siren function.
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
vehicle’s steering wheel horn ring button (if the vehicle’s horn
has been wired to the BETA1), 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 steering wheel horn button
(if the vehicle’s horn has been wired to the
BETA1), 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 Adjustment Screw
The Volume Screw controls the volume of public address
function. Volume is increased by rotating the screw in a
clockwise direction and decreased by rotating the screw in a
counter-clockwise direction. The volume screw has no effect on
any siren tones produced.
Rotary Switch
The rotary knob controls the siren and PA (public address)
functions of the
BETA1™
. There are 7 positions that may be
selected. Each position and it’s function is 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 BETA™ remote amp must be connected to the
two-way radio as outlined in its manual). If the horn ring is wired
as shown and the horn ring is pressed, an “airhorn” siren tone
will be generated by your vehicle’s loudspeaker.
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 when the
BETA1 microphone is in use. The volume level of PA
transmissions is controlled by the volume adjustment screw. If
the horn ring 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 horn ring generates a tone that rises in
pitch to a pre-set level. This tone is generated for as long as the
horn ring is pressed.
HF (Hands Free Operation) -
When the rotary knob is in the HF
position, the siren functions of the BETA I are placed in a stand-
by mode. Siren tones are activated by a single “tap” on the
vehicle’s steering wheel horn ring button (if the vehicle’s horn
has been wired to the BETA I). The first “tap” produces a Wail
