(Electrical Connections: Siren Amplifier CONT’D)
Siren electrical power connections to
the amplifier are made using a
removable connector located on the
back of the amplifier case.
The power supply to the siren unit must
be capable of delivering peak currents up to
50 amps for adequate short circuit protection
and reliable operation. The preferred source
is directly at the vehicle battery. The unit is
internally fused. The wiring diagram on the next page shows detail of how to wire
the connector on the amplifier to the vehicle.
Make all electrical connections to the power connector before installing the
connector on the unit.
Mandatory Siren
Wiring Connections:
BLACK LEADS:
(GROUND) - Connect BOTH black wires to the negative of the battery, or
to a good chassis ground. Be sure to use minimum size #14 AWG wire.
RED LEADS:
(POWER/+12VDC) - Connect BOTH red wires to the positive of the
battery, or to a high current power buss. Be sure to use minimum size
#14 AWG wire.
BROWN LEADS:
(SPEAKER) - Connect one lead to each terminal or lead of the speaker.
If connecting a second speaker in parallel,
you must observe the polarity
of the speakers (phasing)
.
Be sure that the positive terminals of both
speakers are connected together to the
same
brown wire from the siren
.
PINK LEAD:
(IGNITION SWITCHED POWER) - Connect the pink wire to your ignition-
controlled power (or other switched power source). This will turn the
power to your unit on and off.
Optional Siren Wiring Connections:
BLUE LEADS:
(RADIO REPEAT) - Connect one blue lead to each terminal of the two-
way radio speaker or output connector of the radio. Use #18 AWG wire.
GREEN LEAD:
(AUX) - Use if you would like to activate the siren’s AIR HORN when the
vehicle horn is pressed. Connect to horn ring circuit or other remote
switch. Circuit may be positive or negative with proper jumper selection.
See
Auxiliary Input Polarity
section on page 3 for jumper details. NOTE:
Cut lead short if not used & insulate with electrical tape.
Optionally this may be used to mimic the Manual button function when
the vehicle’s horn is pressed. See
Auxiliary Control
on pages 6-7 for
Control Head jumper setting.
WHITE LEAD:
(PARK-KILL) - Connect to dome light or added door switch. Circuit may
be positive or negative with proper jumper selection. See
Park Kill Input
Polarity
section (page 4) for jumper details.
NOTE: If not used, cut lead short and insulate with electrical tape.
ORANGE LEAD:
(HORN RING TRANSFER or LOW CURRENT OUTPUT) -
You only need to
connect this wire if you will also be connecting the green AUX wire to
your horn ring circuit, thus enabling the driver to control the siren
functions by using the vehicle horn.
This output is enabled whenever
the handset is activated with the recessed On/Off switch on the side
and it temporarily deactivates the vehicle’s horn. This allows the use
of the horn ring switch without actually sounding the vehicle’s horn.
Connect the Orange wire to the Horn Ring Transfer Relay as shown the
HRT Wiring Diagram
on page 14.
NOTE: If not used, cut lead short and insulate with electrical tape.
