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.
■ 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 analyses
them with proprietary acoustic software to determine if the
glass has been struck.
■ Backup Battery - The 520T keeps the system armed, triggers
the alarm and keeps the Immobilisation circuits active if the
main battery is disconnected.
■ Bonnet Lock - Prevents the vehicle’s bonnet from being
opened without a key, keeping thieves away from the sys-
tem’s siren, the battery connections, and other components
under the bonnet.
■ Field Disturbance Sensor - An invisible dome of coverage is
established by installing the 508D “radar” sensor. Your system
can react to any intrusions into this field with the full trig-
gered sequence.
■ Remote Starter - A remote engine starting system designed
for fuel-injected automatic transmission vehicles. The 551T is
activated by pressing a spare button on your remote control.
NOTE: The Remote Starter has not been evaluated by Thatcham.
