Expansions
Listed below are some of the many expansion options available for
use with your system. Please consult your dealer for a detailed
explanation of all the available options.
Audio Sensor: Metal on glass, glass cracking, and breaking glass
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
interrupt 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 Locks: This system offers lock outputs that can control
some manufacturers' power door lock systems. For other systems,
additional parts may be required.
