Expansions
Listed below are some of the many expansion options available.
Please consult your dealer for a complete explanation of all the
options available to you.
Field Disturbance Sensor: An invisible dome of coverage is estab-
lished by installing the 508D “radar” sensor. Your system can react
to any intrusions into this field with the full triggered sequence.
Backup Battery: The 520T keeps the system armed, triggers the alarm
and keeps the starter kill active if main battery is disconnected.
Electronic Hood Lock: Prevents the vehicle’s hood from being
opened whenever the system is armed, keeping thieves away from
the system’s siren, the battery connections, and other components
under the hood.
Audio Sensor: Metal on glass, glass cracking, and breaking glass
produce distinctive acoustic signatures. The 506T audio sensor
uses a microphone to pick up sounds, then analyzes them with pro-
prietary acoustic software to determine if the glass has been struck.
Power Trunk Release: The output of the system can operate
a factory power release for the vehicle’s trunk or hatch. Although
the on-board relay can control most power trunk releases, in some
cases an optional relay is required. If the factory release is not power-
activated, DEI's 522T trunk release solenoid often can be added.
