Rotary Switch Operations
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 loud-
speaker (Unit must be connected to the two-way radio as out-
lined in this manual).
With the Rotary Switch in this Position:
Pressing the MAN button has no effect.
Activating the HORN RING input has no effect.
Activating the AUX ENABLE input has no effect.
PA (Public Address)
- When the rotary switch is in this position
the siren is in a standby state where no tones have been
activated, but is waiting for another action to be taken by the
operator. This position is often the best choice when public
address is required.
With the Rotary Switch in this Position:
Pressing the MAN button will result in the AIRHORN tone
until the MAN switch is released.
Activating the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
Activating the AUX enable input will result in a repeating
WAIL tone.
MAN (Manual Siren)
- When the rotary switch is in this position
the siren is in a standby state where no tones have been
activated, but is waiting for another action to be taken by the
operator. This position is often the best choice when manual
operation of the siren is desired.
With the Rotary Switch in this Position:
Pressing the MAN switch will result in a WAIL tone ramping
up to peak frequency and stopping when the MAN switch is
released.
Activating the HORN RING input will result in a WAIL tone
ramping up to the peek frequency and stopping when the
HORN RING input is released.
Activating the AUX enable input will result in a repeating
WAIL tone.
HF (Hands Free Operation)
- When the rotary knob is in the
HF position, the siren functions are placed in a stand-by mode.
Siren tones are activated by a single tap on the MAN button or a
single tap on the vehicle’s steering wheel horn ring (if the vehi-
cle’s horn has been wired to the HORN RING input). The first
tap produces a WAIL tone (a steady rise and fall tone). A sec-
ond 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.
With the Rotary Switch in this Position:
Pressing the MAN button will result in the HF cycle as
described above.
Activating the HORN RING input will result in the HF cycle
as described above.
Activating the AUX ENABLE input will start the HF cycle.
Releasing the AUX ENABLE will stop the cycle.
WAIL (Wail Tone)
- When the rotary knob is in the WAIL posi-
tion, a steady, rise and fall tone (wail) is produced.
With the Rotary Switch in this Position:
Pressing the MAN button will change the siren tone to a yelp
pattern.
(a fast rise and fall tone)
Pressing the MAN button a
second time returns it back to a wail tone.
Activating the HORN RING input will change the siren tone
to a yelp pattern. (a fast rise and fall tone) Activating the
HORN RING input again returns it back to a wail tone.
Activating the AUX ENABLE input has no effect.
YELP (Yelp Tone)
- When the rotary knob is in the YELP
position, a fast, rise and fall tone is produced.
With the Rotary Switch in this Position:
Pressing the MAN button will result in the AIRHORN tone
until the MAN switch is released.
Activating the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
Activating the AUX ENABLE input has no effect.
PIER (Piercer
TM
Tone)
When the rotary knob is in the T3
position, an extremely fast, rise and fall tone is produced. May
be used for HI / LO and auto sequence in some applications.
With the Rotary Switch in this Position:
Pressing the MAN button will result in the AIRHORN tone
until the MAN button is released.
Pressing the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
Activating the AUX ENABLE will have no effect.
