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 loudspeaker.
The 295HFANC must be connected to the two-way radio as
outlined in this manual.
With the Rotary Switch in this Position:
•
Pressing the MAN switch will result in SITEST (See SITEST
section)
•
Pressing the HORN switch will result in the AIRHORN tone
until the HORN switch is released.
•
Activating the HORN RING input results in the AIRHORN
tone until the HORN RING input is released.
•
Activating the SIREN SHUTDOWN 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 switch will result in a WAIL tone ramping
up to the peak frequency and ramping down to a stop at the
lowest frequency when the MAN switch is released.
•
Pressing the HORN switch will result in the AIRHORN tone
until the HORN switch is released.
•
Activating the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
•
Activating the SIREN SHUTDOWN input has no effect.
•
Activating AUX ENABLE 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.
•
Pressing the HORN switch will result in the AIRHORN tone
until the HORN 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 switch is released.
•
Activating the SIREN SHUTDOWN input has no effect.
•
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 of the 295HFANC 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 vehicle’s horn has been wired to the HORN RING
input). 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 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 switch will result in the HF cycle as
described above.
•
Pressing the HORN switch will produce the AIRHORN tone
until the HORN switch is released.
•
Activating the HORN RING input will result in the HF cycle as
described above.
•
Activating the SIREN SHUTDOWN input will shut the WAIL,
YELP and PIERCER tones down. However the HORN and
the HORN RING switch will activate an AIRHORN tone and
the MAN switch will activate a momentary WAIL tone.
•
Activating the AUX ENABLE input will start the HF cycle.
WAIL (Wail Tone)
- When the rotary knob is in the WAIL position,
a steady, rise and fall tone (wail) is produced.
With the Rotary Switch in this Position:
•
Pressing the MAN switch will change the siren tone to a yelp
pattern (a fast rise and fall tone).
•
Pressing the MAN switch a second time returns it back to a
wail tone.
•
Pressing the HORN switch will result in the AIRHORN tone
until the HORN switch is released.
•
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 a second time returns it back
to a wail tone.
•
Activating the SIREN SHUTDOWN input will shut the WAIL,
YELP tones down. However the HORN and the HORN RING
switch will activate an AIRHORN tone, and the MAN switch
will activate a momentary 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 switch will change the siren tone to a
PIERCER pattern (an extremely fast rise and fall tone).
Pressing the MAN switch a second time returns it back to a
YELP tone.
•
Pressing the HORN switch will result in the AIRHORN tone
until the HORN switch is released.
•
Activating the HORN RING input will change the siren tone to
a PIERCER pattern. Activating the HORN RING input a
second time returns it back to a YELP tone.
•
Activating the SIREN SHUTDOWN input will shut the YELP
and PIERCER tones down. However the HORN RING switch
will activate an AIRHORN tone and the MAN switch will
activate a momentary WAIL tone.
•
Activating the AUX ENABLE input has no effect.
T3 (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 switch will result in the AIRHORN tone until
the MAN switch is released.
•
Pressing the horn switch will result in the AIRHORN tone until
the HORN switch is released.
•
Activating the HORN RING input will result in the AIRHORN
tone until the man switch is released.
