Protect your motorcycle or scooter with the Datatool S4 Green C221, an advanced security alarm designed to provide extra protection against theft and tampering.
This system is specially designed for motorcycles and scooters that already have a Thatcham Category 2 approved immobiliser, allowing their security protection to be upgraded to Thatcham Category 1 when correctly installed and combined with the existing approved immobiliser.
Thatcham is a well-known UK organisation that tests and certifies vehicle security systems to recognised standards.
Thatcham-approved security systems are widely recognised by UK insurance companies and can help demonstrate that your motorcycle has an approved level of theft protection.
Thatcham Category 1 – Alarm + Immobiliser
Combines an electronic immobiliser with an approved alarm system, offering protection against unauthorised starting, movement and tampering.
Thatcham Category 2 – Immobiliser Only
An approved electronic immobiliser that prevents the engine from being started without the correct key or authorisation, but does not require a full alarm system.
If your motorcycle already has a Thatcham Category 2 approved immobiliser, the Datatool S4 Green adds the alarm protection needed to upgrade the combined security system to Category 1 status, subject to the applicable approval and installation requirements.
This means extra protection without needing to replace an existing approved immobiliser.
