Amplitude Shift Keying—a method of transmitting data.
Control Unit:
The "brain" of your system. Usually hidden under
the dash area of the vehicle. It houses the microprocessor which
monitors your vehicle and controls all of the system's functions.
Fail Safe Starter Kill
: An automatic switch controlled by the secu-
rity 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, in Valet mode, or
should the starter interrupt switch itself fail. Your system is ready
for this feature, however installation may require additional labor.
Input
: A physical connection to the system. An input can be
provided by a sensor, pinswitch or through an existing system in
the vehicle, such as ignition or courtesy lights.
In-vehicle status LED
: A 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 system or sensors.
Shock Sensor
: This is a sensor mounted in the vehicle that is
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.
