Glossary of Terms
Control Unit: The “brain” of your system. Usually hidden under-
neath the dash area of the vehicle. It houses the microprocessor
which monitors your vehicle and controls all of the system func-
tions.
Failsafe ® Starter Kill: Located on-board the control module, this
is an automatic switch controlled by the system which prevents
the vehicle’s starter from cranking whenever the system is armed.
The vehicle is never prevented from cranking when the system is
disarmed or if the starter kill switch fails.
LED: Red light mounted somewhere in the vehicle. It is used to
indicate the status of your system. It is also used to report trig-
gers and faults in the system or sensors.
Transmitter: Hand-held, remote control which operates the vari-
ous functions of your system.
Valet ® Switch: A small push button switch mounted somewhere
inside the vehicle that is used by the installer for programming the
system. It can also be used to override the starter kill and other
expansion options that have been added to your system. Consult
your dealer for details.
