Thatcham approved alarm

Thatcham approved alarms differ for vehicle types and specification. If your vehicle has an existing cat2 immobiliser then you only require a Thatcham approved alarm upgrade rather than a cat1 alarm and immobiliser.

There are many car Thatcham approved alarms on the market but if you have an open top car it is important to choose one that has a microwave interior sensor rather then an ultrasonic sensor. A universal aftermarket Thatcham approved alarm with a pair or remotes will be suitable for all cars rather then one which utilises the existing remotes as some cars are not not suitable for this type of system.

Van Thatcham approved alarms are similar to car alarms but they may require extra door sensors to be installed to protect the cargo area if there are no door switches in place. Usually there is more space in a van to install and hide a Thatcham approved alarm so there is no need to pay more for a compact model designed to fit smaller cars or where space is limited.

Motorcycle Thatcham approved alarms are very compact and more watertight then any other type of alarm as there is less space and more exposure to the rain on a motorbike. As with another Thatcham approved alarm you have a choice of alarm upgrade if your bike already has a cat2 immobiliser.

Motorhome and caravan Thatcham approved alarms usually require extra sensors such as; PIR to protect the living area, closed loops for gas bottles, bikes and other loose items, door, window and locker switches to protect openings that have no switches. A motor home Thatcham approved alarm will have the ability to disarm the PIR sensor zone so that you can sleep and move around at night while all the other sensors and zones are armed.
