(2) Dual-wire parking light systems A few
vehicles (mainly European) have
separate circuits for the parking lights on
the right and left sides of the vehicle.
In this case, connect one non-fused
ORANGE WIRE to the right-side circuit,
and the other to the left-side circuit.
D. Dual Power Protection (DPP
TM
)
With DPP, if you connect the fused ORANGE
WIRE to +12V, it becomes a second power
source for the alarm brain if the fused RED
WIRE is cut. This works only if this ORANGE
WIRE is connected to a separate source of
+12VDC from the RED WIRE.
Connector 2 (8-pin connector)
BLACK WIRE (to chassis ground) , fig. 2
Choose a good chassis ground location. This is
the most important point of a successful
installation. A poor ground connection will
cause the siren to continuously emit a low siren
sound whenever the alarm is armed.
Use one of the cars factory bolts to connect to
chassis ground. If none is available, scrape
paint and dirt from the metal surface, and use a
grounding lug and star washer.
Connector 2 (8-pin connector)
WHITE WIRE (to starter disable),
figs. 3a, 3b
Connect to an optional 30A relay to prevent the
car from starting when the alarm is armed.
A. Locate the starter solenoid wire (carries
power from the ignition switch to the starter
solenoid). This wire must show +12VDC
only when the ignition is in the start position.
B. Cut the starter solenoid wire.
C. Test the starter solenoid wire as follows:
(1) If the wire is cut before the engine is
started, the engine should not turn over.
(2) If the wire is cut while the engine is
running, there should be no effect.
D. Connect the WHITE WIRE and the two halves
of the cut starter solenoid wire to the relay as
shown in fig. 3a.
E. If the engine still starts, connect terminal 86
to a wire which shows +12VDC when the
engine is both starting and running (fig. 3b).
F. NOTE regarding N.C./N.O. output The
starter disable output is programmable for
N.C. or N.O. operation. Default is N.C.
(See PROGRAMMING, page 18.) If N.O.
starter disable output is required, connect the
ignition switch side of the starter solenoid
wire to terminal 87 of the starter disable
relay instead of 87a. All other connections
are the same.
Connector 2 (8-pin connector)
PINK WIRE (to siren), fig. 4
A. Mount the siren under the hood to the
vehicles metal body as close to the grill as
possible for best sound. The siren must not
touch the engine. Mount with the mouth
facing down so water will not collect inside.
