Glossary of terms

regardless of whether or not the alarm is armed. If AED is programmed on, the starter of the
vehicle will be disabled 30 seconds after the ignition is turned off.

houses the microprocessor which monitors your vehicle and controls all of the system's functions.

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 labour.

responsible for generating the "chirps" you hear, as well as the six tones you hear while the alarm
is triggered.

Trigger or Triggered Sequence: This is what happens when the alarm "goes off" or "trips". The
triggered response of your system consists of the siren sounding and parking light flashing for the

override the alarm when a transmitter is lost or damaged, or to enter or exit Valet mode.
