ELECTRICAL CONNECTIONS
Electrical connections to the unit are made
using a removable pressure connector
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 ca-
pable 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 connec-
tion, 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 acti-
vation by an external source of
either the Horn or Man/Phsr
function. The adjacent diagram
shows three connection exam-
ples. See the INSTALLER-
SELECTABLE OPTIONS sec-
tion for programming details.
NOTE: Permanent disconnec-
tion 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 adja-
cent diagram shows two connection examples. See
the INSTALLER-SELECTABLE OPTIONS section for
programming details.
