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. 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 (model 295HFSM5
produces mechanical wail).
•
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 (model 295HFSM5
produces mechanical wail).
•
Activating the SIREN SHUTDOWN input has no effect (model
295HFSM5 will initiate ‘Siren Brake’).
•
Activating the AUX ENABLE (or slide switch position 3, if selected)
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.
•
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 (Or slide switch position 3, if
selected) will result in a repeating WAIL tone.
HF (Hands Free Operation) -
When the rotary knob is in the HF
position, siren functions are placed in a stand-by mode. Siren tones are
activated by a single “tap” on the MAN button or 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 result in 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 (or slide switch position 3, if
selected) will start the HF cycle.

pattern. (a fast rise and fall tone).
•
Pressing the MAN switch a second time returns it back to a Wail
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
