Autowatch Alarm for Thatcham Approval

Alarm ultrasonic protectionThis Autowatch alarm is used when customers need a device that has Thatcham Approval and is a Cat 1 for insurance purposes. It will give ultrasonic interior protection, and be connected to doors, boot and bonnet, triggering the battery back-up siren should intrusion take place. The device uses your factory supplied hand-held remotes already in use for locking and unlocking the doors.

The 375 CLAM is ideally suited to older vehicles with wiring systems that are pre CANBus in design. These cars would have been fitted with a factory immobiliser and usually central locking but not a full alarm system. For some van alarms e.g. Vauxhall Vivaro 2004 to 2014 this device is the only real solution to avoid other electrical systems from malfunctioning in the vehicle. Please note we can advise you on the best system for your make and model of car or van.

For customers who find themselves supplied with one remote and one backup key with their vehicle, additional remotes can be added to this system. These remotes will not unlock the doors, as this can only be done with the factory remote, however customers can then disable the alarm with the new remote and open the doors with the backup key. Customers requiring new remotes will be charged £100 for two remotes.
