Glossary of Terms
Control Unit
The “brain” of your system. Usually hidden underneath the dash
area of the vehicle. It houses the microprocessor which monitors your vehicle
and controls all of the alarm's functions.
FailSafe
®
Starter Kill
An automatic switch controlled by the security 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 dis-
armed, in valet mode, or should the starter kill switch itself fail. Your system is
ready for this feature, however installation of this feature may require addi-
tional labor.
Input
A physical connection to the system. An input can be provided by a sen-
sor, pinswitch or to existing systems in the vehicle, such as ignition or cour-
tesy lights.
LED
Red light mounted somewhere in the vehicle. It is used to indicate the
status of your system. It is also used to report triggers and faults in the sys-
tem or sensors.
Shock Sensor
This system is packaged with a Stinger
™
DoubleGuard
®
shock
sensor. This sensor is mounted in the vehicle and designed to pick up impacts
to the vehicle or glass.
Siren
Noise generating device usually installed in the engine compartment of
the vehicle. It is responsible for generating the “chirps” you hear, as well as
the six tones you hear while the alarm is triggered.
Transmitter
Hand-held, remote control which operates the various functions
of your system.
Trigger or triggered sequence
This is what happens when the alarm “goes
off” or “trips.” The triggered sequence of your system consists of 30 seconds
of siren sounding and parking light flashing.
Valet
®
Switch
A small push button switch mounted somewhere inside the
vehicle. It is used to override the alarm when a transmitter is lost or damaged,
or to put it into Valet
®
mode.
Warn Away
®
response
Lighter impacts to the vehicle will generate the Warn
Away
®
response. It consists of several seconds of siren chirps and parking
light flashes.
Zone
A zone is a separate input that the alarm can recognize as unique. Each
input to the system is connected to a particular zone. Often two or more inputs
may share the same zone.
