Audio Sensor: Metal on glass, glass cracking, and breaking glass
each produce distinctive acoustic signatures. The 506T audio
sensor uses a microphone to detect these sounds, and then
analyzes them with proprietary acoustic software to determine if
the glass has been tampered with or broken.
Backup Battery: The 520T Backup Battery ensures that the system
stays armed, triggers the alarm and keeps the optional starter kill
active if main battery power is disconnected.
Field Disturbance Sensor: An invisible dome of coverage is estab-
lished by the 508D "radar" sensor. Your security system will respond
to any intrusions into this field by initiating the triggered sequence.
Power Trunk Release: The output of the system can operate
a factory power release for the vehicle's trunk or hatch. An optional
relay is required. If the factory release is not power-activated, then
DEI's 522T trunk release solenoid can be added in most cases.
Power Window Control: Automatic power window control is
provided with the 529T and 530T systems. These options operate
power windows, by rolling them up, down, or both up and down.
The 530T also offers one-touch switch operation.
Valet
Start System: For the ultimate in convenience, the Valet
Start System can start your vehicle, monitor engine functions and
activate your climate control system with a push of a button! Over-
rev protection, open-hood lockout, brake pedal shutoff and
automatic timer shutoff are included. (This option is available only
for fuel-injected, automatic-transmission vehicles.)
