Expansions
Here we have listed only 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
established by the 508T “radar” sensor. Your system can react to
any intrusions into this field with the triggered sequence.
Backup Battery: The 520T keeps the system armed, triggers the
alarm and keeps the starter kill active if main battery power is dis-
connected.
Electronic Hood Lock: This prevents the vehicle’s hood from
being opened whenever the system is in alarm mode, keeping
thieves away from the system’s siren, the battery connections, or
other components under the hood.
Audio Sensor: Metal on glass, glass cracking, or breaking glass
produce distinctive acoustic signatures. The 506T audio sensor uses
a microphone to pick up sounds, and then analyze them with pro-
prietary acoustic software to determine if the glass has been struck.
Power Trunk Release: One of the auxiliary outputs of the system
can operate a factory power release for the vehicle’s trunk or
hatch. (An optional relay may be required.) If the factory release
is not power-activated, DEI's 522T trunk-release solenoid can
often be added.
