This section will outline the operation of the siren in the factory
default configuration. Refer to the Scan-Lock™ section on the
following page for information and procedures on how to
customize the operation of this siren.
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 unit must be connected to the two-way radio as
outlined in this manual).
With the Rotary Switch in this Position:
•
Activating the HORN button will produce the AIRHORN tone
until released.
• Pressing the MAN button will start SI TEST® as described on
Page 5.
• Activating the HORN RING input will produce the AIRHORN
tone until the MAN switch is released.
• Activating the AUX ENABLE input has no effect.
MAN 1 (Manual Siren #1) - 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.
With the Rotary Switch in this Position:
• Activating the HORN button will produce the AIRHORN tone
until released.
• Pressing the MAN button will produce the AIRHORN tone until
the MAN switch is released.
• Activating the HORN RING input will produce the AIRHORN
tone until the HORN RING input is released.
• Activating the AUX enable input will produce a repeating WAIL
tone.
MAN 2 (Manual Siren #2) - When the rotary switch is in this
position the siren is in a standby state. No tones will be activated
until another action is taken by the operator.
With the Rotary Switch in this Position:
•
Activating the HORN button will produce the AIRHORN tone
until released.
• Pressing the MAN switch will produce a WAIL tone. This tone
will ramp up to peak frequency and stop when the MAN switch
is released.
• Activating the HORN RING input will produce a WAIL tone. This
tone will ramp up to peak frequency and stop when the HORN
RING input is released.
• Activating the AUX enable input will produce a repeating WAIL
tone.
HF (Hands-Free Operation) - When the rotary knob is in the HF
position, the siren functions are placed in a standby 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:
• Activating the HORN button will produce the AIRHORN tone
until released.
• Pressing the MAN button will produce the HF cycle as
described above.
• Activating the HORN RING input will produce the HF cycle as
described above.
• Activating the AUX ENABLE input will start the HF cycle.
Releasing the AUX ENABLE will stop the cycle.
T1 (Tone #1) - When the rotary knob is in the T1 position, a
steady, rise and fall tone (WAIL) is produced.
With the Rotary Switch in this Position:
•
Activating the HORN button will produce the AIRHORN tone
until released.
• 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 WAIL.
• Activating the HORN RING input will change the siren tone to
YELP. Activating the HORN RING input again to return to a
WAIL tone.
• Activating the AUX ENABLE input has no effect.
T2 (Tone #2) - When the rotary knob is in the T2 position, a fast,
rise and fall tone (YELP) is produced.
With the Rotary Switch in this Position:
•
Activating the HORN button will produce the AIRHORN tone
until released.
• Pressing the MAN button will produce the PIERCER tone.
Pressing the MAN switch a second time returns it back to
YELP.
• Activating the HORN RING input will produce the AIRHORN
tone until the HORN RING input is released.
• Activating the AUX ENABLE input has no effect.
T3 (Tone #3) - When the rotary knob is in the T3 position, an
extremely fast, rise and fall tone is produced.
With the Rotary Switch in this Position:
• Activating the HORN button will produce the AIRHORN tone
until released.
• 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
