(Standard Installation)

The AVS 24 volt S4 car alarm is a quality, robust alarm for 24 volt vehicles which is AS/NZS Standards Certified.

The cabin of the car is protected with a dual stage shock sensor.

Plus the alarm includes triple immobilisation and seamless turbo timer integration. It can be operated either by waterproof AVS remotes or in many cases, by your car’s factory remote.


Two waterproof AVS rolling code remotes

The 24 volt AVS S4 alarm comes the popular waterproof AVS remotes to arm/disarm your alarm and lock/unlock the doors. Because remotes get the most wear and tear of any part of the alarm, choosing a system with robust, reliable, and in this case waterproof remotes, makes a big difference to how well the system functions. Plus only with AVS do you get a 3-year warranty on your remotes.

Central locking

The alarm can lock/unlock the doors when the alarm is armed/disarmed for easy keyless entry. AVS also supplies 24 volt door motors and relays if your vehicle requires additional parts for keyless central locking.

Or control the alarm with your car’s factory key

If you have a factory key with a lock/unlock button with most vehicles you can arm/disarm the AVS alarm at the same time. Boot release will also disarm the alarm and open the boot. This is a great feature giving all the functionality of a premium alarm system with ease of use.

Turbo timer integration

Enjoy seamless integration with turbo vehicles. The alarm can be armed while the car runs on a timer. If the alarm is triggered the car shuts down and the alarm sounds. There are two options:

  1. AVS turbo timer – the most secure option is to use the alarm’s in-built turbo timer. Choose a run time of 1, 2 or 4 minutes. The timer can also be shut down via the AVS remote.
  2. Turbo timer interface – link the alarm up with an external turbo timer allowing the alarm to be armed while the car runs on the timer.


The AVS S4 alarm includes three immobiliser circuits. For maximum security fuel pump, ignition system and starter motor immobiliser cuts are made so the car cannot be started unless it is disarmed via the remote. The system will immobilise 40 seconds after the ignition is turned off or when the alarm is armed.

Note: it is not possible to install all three immobiliser circuits on diesel vehicles.

Intrusion alerts

Intelligent dual stage shock sensor

The shock sensor helps protect the body and cabin of the car by giving a warning on a light impact and a full alarm on a heavy impact to the vehicle.

This clever sensor can distinguish between environmental shocks such as trucks or aircraft and a thief attempting to break in as well as auto adjust its sensitivity for the environment on arming to help prevent false triggers.

Door, bonnet and boot protection

A good standard alarm installation will include protection for the doors, bonnet or boot. If any of these are opened while the alarm is armed the alarm will trigger.

If you choose a budget installation please check with your installer that these important features are included (the bonnet is an important inclusion because many thieves will initially pop the bonnet to see if the alarm triggers and / or to cut the siren wires).

Data battery back-up siren

This self powered siren communicates independently with the alarm so it cannot be fooled into turning off like normal battery back-up sirens. The siren will sound for 30 seconds if any of above intrusions are detected.
