Blue Negative Instant Trigger Wire
Page 16
The Blue wire is a Negative instant trigger used primarily to detect entry into the hood or trunk area of a vehicle. Complete functions are:
A)
When the security system is armed, grounding the Blue wire will trigger the system, causing the siren to sound, the exterior lights to flash, and the doors
to relock.
B)
If the Blue wire is grounded when the system is armed, the Circuit Bypass feature will leave the Blue wire circuit unprotected until it becomes ungrounded.
C)
If the Blue wire becomes grounded during the 90 second Automatic Rearming cycle, or the 30 second Last Door Arming cycle, that automatic function
will be suspended for as long as the door is open. When the door is closed, Last Door Arming will start.
D)
When the Last Door Arming feature is utilized, if the Blue wire is grounded when the last door is closed, the Last Door Arming process will not start
until the Blue wire is ungrounded.
E)
If the security system is triggered by the Blue wire, the LED Status Light will flash 2 times and pause until the ignition switch is turned “on”. The
EG-1600
ATV
will additionally display "H" on the Information and Programming Module's digital display. The system does not have to reset itself for
this feature to operate.
F)
When the ignition switch is "off", if the Blue wire becomes grounded, the LED Status Light will flash 2 times and pause for as long as the Blue wire is
grounded. This is the Zone Testing feature, which allows the installer or vehicle owner to visually see trigger circuits which are in a violated state.
CONNECTION: The included pin switches may be installed to provide this trigger circuit Or, if there are existing switches (example: a light in the luggage
compartment or a "Trunk Ajar" light in the dash), the Blue wire may be connected directly, provided this is a negative ground switching circuit. An indication
of such a circuit is the wire having no voltage present when the hood or trunk is open, and up to 12 volts when the hood or trunk is closed. This circuit cannot
be used wit
h mercury switch types of hood or trunk
lights. If the vehicle is equipped with a usable trunk or hood circuit, locate the proper wire and splice
Blue wire direct.

When wiring more than one of the
vehicle's circuits and/or additional circuits
to this wire, diode-isolation of the circuits
may be required. An example would be
wiring a hood pin switch and trunk light
switch together. Without isolating, the trunk
light will turn "on" whenever the hood is
raised. Also, diode-isolation is necessary
when combining electronic sensors together
or in the same circuit with pin switches.
