(Electrical Connections CONT’D)
The power supply of 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 power
connector on the amplifier to the vehicle. The communication cable should have
one end plugged into the amplifier (telephone style jack) and the other end
plugged into the control head.
Siren
Wiring Connections:
BLACK LEADS:
You MUST connect BOTH black wires when using two 100W driver speakers.
Connect to the negative of the battery, or to a good chassis ground. Be sure to use minimum
size #14 AWG wire.
RED LEADS:
You MUST connect BOTH red wires when using two 100W driver speakers. Connect
to the positive of the battery, or to a high current power buss. A power relay may also be
used. Be sure to use minimum size #14 AWG wire.
BROWN LEADS:
Connect one lead to each terminal or lead of the speaker. Be sure to use minimum
size #14 AWG wire
. 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
. In which case, the
negative terminals of both speakers would also be connected together to the other brown
wire.
PINK LEAD:
Connect the pink wire to you ignition-controlled power (or other switched power
source). This will turn the power to your unit on and off.
Siren Optional Connections:
BLUE LEADS:
Use for radio repeat. Connect one blue lead to each terminal of the 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 4
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 7-8 for Control Head jumper setting.
WHITE LEAD:
Used for Park Kill (Cut-off). Connect to dome light or added door switch. Circuit
may be positive or negative with proper jumper selection. See INSTALLER-SELECTABLE
OPTION section (page 4) for jumper details.
NOTE: Be sure to cut lead short if not used and insulate with electrical tape.
ORANGE LEAD:
Used for Horn Ring Transfer Relay, or other low current output. This output is
activated by pushbutton switch S5. Optionally it can be ON at siren boot (see
Activate
Horn Ring Transfer on start-up
on pages 7-8). The HRT will deactivate the vehicle’s
horn when it is on (S5 on). This allows the driver to use the horn ring to control the siren
without activating the vehicle’s horn.
Connect the Orange wire to the Horn Ring Transfer Relay or other low current device
(Maximum 2A)
. This output may also be used to drive an external relay when higher
current is required. NOTE: Cut lead short if not used & insulate with electrical tape.
See the
HRT Wiring Diagram
on page 15 for more detail.
