Please follow these guidelines when wiring the siren:
•
Use only high quality crimp connectors.
•
Make sure all connections are tight.
•
Route wiring to prevent wear, overheating and interference with air bag
deployment.
•
Use grommets and sealant wh en passing through compartment walls.
•
Minimize the number of splices to reduce voltage drop.
•
Ground connections should only be made to substantial chassis components,
preferably directly to the negative of the vehicle battery.
•
Install and check all wiring before connection to vehicle battery.
Siren
Wiring Connections:
Siren input and output
connections are made on the
back of the unit through a
12-pin connector and wiring
harness (part # SWH-48).
Please review the Siren Wiring diagram on
page 8
and make your connections
as follows:
BLACK
: (Pins 2 & 5)
Ground
- Connect these leads to the negative of the
battery, or to a good chassis ground. You MUST connect both
leads if you are using two 100-watt speakers. Be sure to use
minimum size #14 AWG w ire.
RED
: (Pins 1 & 4)
Power
- Connect both leads to the positive side of the
battery, or to a high current power buss. You MUST connect both
leads if you are using two 100-watt speakers. A power relay may
also be used. Be sure to use minimum size #14 AWG wire.
YELLOW
: (Pin 11)
Ignition Switched Power
- Connect to +12VDC through
a switched power supply (possibly ignition). This will turn the
siren and light controls on and off. Be sure to use minimum size
#18 AWG wire.
NOTE:
This wire performs the same function as
the On/Off switch on the front of the unit.
ORANGE
: (Pin 9)
Backlight Power
- This lead supplies power for the
backlighting of the faceplate. Connect it to +12VDC from the
dash lights, parking lights or other switched source. Be sure to use
minimum size #18 AWG wire.
Note: The unit will still function
without power to this wire. There will not be any backlighting or
visual feedback on the switches though.
BROWN
: (Pins 7 & 12)
Speaker Output
- 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.
