ELECTRICAL CONNECTIONS
Disconnect vehicle battery before making any electrical connections.
Electrical connections to the unit are made using a
removable terminal block plug located on the back. A
label on the unit identifies the terminal function. You
should install the connector on the unit before wiring. If
the unit needs service the connector can be easily
removed without unwiring the connector.
The power supply of the 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.
Attach leads by stripping 3/8", inserting into connector
and clamp by tightening screw. Make sure the screw is
tight and the wire can't be pulled out. Failure to
adequately tighten the screw can result in improper
operation or burning the connector and wire.
Wire Size and Termination - The diagram shows the
minimum wire size used for each connection, along with
recommended lead color. If the wire is longer than 10 ft.
use the next larger wire size. Use only high quality
crimp connectors for installation on the vehicle.
Auxiliary Input Connection - The Auxiliary
Input allows activation by an external source
of either the Horn or Man/Phsr function. The
adjacent diagram shows three connection
examples. See the INSTALLER-
SELECTABLE OPTIONS section for
programming details.
NOTE: Permanent disconnection of the
vehicle horn is NOT recommended.
Cutout Input Connection - The Cutout Input turns off any siren
tone output when activated, and remains off until a control is
activated or changed. The adjacent diagram shows two connection
examples. See the INSTALLER-SELECTABLE OPTIONS section
for programming details.
