AVS C4 digital CAN-Bus car alarm

The AVS C4 digital car alarm communicates with your vehicle’s CAN-Bus platform for seamless integration into the factory system. Intrusion detection is provided by an ultrasonic sensor which offers excellent protection for the interior of the car. The car alarm also features a digital battery back-up siren making it even harder for a thief to disable it in the event of an alarm trigger. The AVS C4 alarm is designed to be operated from your car’s factory remote plus it can control other factory features such as window roll up (vehicle dependent).

The AVS C4 car alarm features:

Ultrasonic sensor
The ultrasonic sensor triggers the alarm if a change in air pressure or movement is detected in the cabin giving superior protection for the interior of the car. It also performs well in larger vehicles or frameless windows (such as most Subaru models) where other sensors may not. Learn more about AVS ultrasonic sensors here.

Digital battery back-up siren
This self powered siren communicates independently with the alarm so the siren knows if the alarm is armed or disarmed. This means there is no need for an over-ride key so the siren can be well hidden at installation. The siren will sound for 30 seconds if any of above intrusions are detected.

Door, bonnet and boot protection
A good standard alarm installation will include protection for the doors, bonnet and boot. If any of these are opened while the alarm is armed the alarm will trigger. In a CAN-Bus equipped vehicle normally the doors and boot will trigger the alarm utilising the factory sensors. We recommend also requesting the installation of a bonnet trigger* if the car does not have this as standard.

Control the car alarm with your vehicle’s factory remote*
Simply hop out of the car and lock your vehicle as usual – the alarm will automatically arm from your factory remote. Disarm and boot release (if available) also work as usual (the alarm will disarm if the boot release button is pushed).

Or add a rolling code AVS remote
OR you also have the option to operate the alarm from a separate AVS CAN remote on selected vehicles*. This is a much more cost effective option than purchasing an additional factory remote or as a replacement if you have lost or broken your existing remotes.

Central locking from the remote*
The car alarm will lock/unlock the doors when the car alarm is armed/disarmed.
