Black/Red & Green/Violet Wires -
(Domelight Supervision Input & Output)
The Crime Guard 745i
"domelight supervision". Upon disarming the 745i
flash, in conjunction with the parking lights. If desired, programmable fea-
ture #9 may be used to configure the parking and dome lights to flash, then
illuminate steady upon disarming. This allow the convenience of a lighted
approach to the vehicle and the safety of being able to inspect the vehicle's
interior before entry.
The Green/Violet wire is the dome light supervision output, and the
Black/Red wire is used to select the Positive or Negative polarity which is
needed for the 745i
Smart Trigger Feature:
circuit can be configured to also serve as the "door open" trigger input. This
is the "Smart Trigger" feature which saves installation time while offering
enhanced integration flexibility. The Green/Violet Domelight Supervision
output wire has an additional function; it is also a door trigger input circuit,
serving the same purpose as either the Green or Violet door trigger wires.
CONNECTION GREEN/VIOLET: The proper vehicle wire to connect
the Green/Violet wire to, the dome light activation wire, is common to all the
door pin switches. The dome light activation wire is the same wire that the
Green or Violet wire would be connected to, if either is used instead of
utilizing the Smart Trigger. The correct wire will change polarity as the
doors are opened and closed.
If the vehicle uses a Negative switching dome light system, the activation
wire will have no voltage present and show chassis ground when the doors
are opened, and up to 12 volts when the doors are closed. The correct wire
for a Positive switching type of dome light/door jamb pin switch system will
have 12 volts present when the doors are opened, and chassis ground when
the doors are closed. The correct wire will show these changes when any
of the doors are opened. If the vehicle has delay dome lights, remember to
take this into account when testing.
CONNECTION BLACK/RED: The polarity of the dome light supervi-
sion output must be selected by the connection of the Black/Red wire as
Positive or Negative. Connection of the Green/Violet should have determined
which polarity the vehicle uses to operate the dome light; this is either
