Thatcham category 1 alarm

There are many Thatcham category 1 alarms on the market but before making a choice you need to determine whether your vehicle has a category 2 immobiliser already installed. Newer UK spec cars have them factory fitted as standard for the UK market but if your car has been imported or is very old then it is unlikely to be fitted with a cat 2. A Thatcham category 1 alarm upgrade is all you need for cars with an existing cat 2 immobiliser, otherwise choose a cat 1 alarm and immobiliser.

Thatcham category 1 alarms differ for soft top cars and hard top cars and you will need to buy an alarm with a microwave interior sensor for an open top car. All other vehicles can be fitted with a Thatcham cat 1 alarm with either an ultrasonic interior sensor or microwave sensor.

All Thatcham category 1 alarms have basic features like; perimeter detection, ignition detection, passenger compartment movement detection or glass break and inclination detection, high security remotes, audible warning with battery back-up power supply. Extra sensors and accessories such as dual zone pre warning bleep, radio or SMS pager, tilt or motion sensor, glass break detector or window closure can also be connected to a Thatcham cat 1 alarm to provide extra security.

Thatcham cat 2 immobiliser

There are two popular types of Thatcham category 2 immobilisers available;

• Touchkey immobiliser requires an electronically coded key fob to be inserted into a receptacle on the dash before starting the engine.

• Transponder immobiliser uses a key fob that transmits a wireless coded signal to the engine that allows it to start.

A Touchkey immobiliser is cheaper but requires a modification to be made on the dashboard and requires the driver to insert the touchkey key fob every time they start the engine.

The Transponder immobiliser is very easy to use and you do not even notice that it has been fitted because you start the engine as before without the need to insert a touchkey.
