Glossary of Terms
Control Module: The "brain" of your system. Usually hidden
underneath the dash area of the vehicle. It houses the micro-
processor that monitors your vehicle and controls all of the alarm's
functions.
Input: Any physical connection to the security system. An input
can be provided through a sensor, pinswitch or by existing systems
in the vehicle, such as ignition or courtesy lights.
LED: A red light mounted inside the vehicle, at a location deter-
mined by the installer. The LED indicates the status of your system
and also reports triggers and faults in the system or sensors.
Shock Sensor: A dual-stage shock sensor, which is located on the
control module, and is designed to detect impacts to the vehicle
or glass.
Siren: A noise generating device, usually installed in the engine
compartment of the vehicle. The siren generates the chirps and
tones heard when the system is triggered.
Starter Interrupt Relay: An automatic switch controlled by the
security system that prevents the vehicle’s starter from cranking
whenever the system is armed. The vehicle is never prevented from
cranking when the system is disarmed, in Valet Mode, or if the
starter interrupt relay fails.
