The system comprises an alcohol sensor 12, mounted in a sample chamber 17, combined with a main key 2, which forms an alcohol analyser/immobiliser system which can be fitted to any machine. The device prevents the operation of a machine without the insertion of the key 2, and a satisfactory breath sample which does not contain alcohol above a pre-set limit. The immobiliser key combined with the alcohol sensor chamber incorporates interlocking features of male and female multipin connectors 4 and 5, which can be configured to prevent interchange of keys between devices. |
