just been introduced by Ingersoll Locks Ltd, which claims that it makes lorry hijacking virtually impossible. The device is known as the Mark III AJarmatic and has a code dial giving more than 10,000 possible combinations.
A vehicle fitted with the Alarmatic cannot be driven without knowledge of the code, and any failure to observe the correct procedure sets off a warning siren. So, too, does any attempt to open the side or rear doors without using the correct security drill.
Moreover, if the control box in the driver's cabin is tampered with, the vehicle is automatically immobilized and the siren sounds. This also happens if the doors or bonnet flaps are opened or if attempts are made to tamp or with any other part of the vehicle.
Although operation of the system is simple, the vehicle cannot be driven until the driver has carried out the right drill.When he enters the vehicle, he must ensure that all doors are closed, then dial the previously arranged four-figure code. If he does not start the vehicle within 15sec, the vehicle returns to an alarmed condition and a turn of the ignition key after this period sets off the siren. It also cuts off the fuel supply in the case of a diesel vehicle or the ignition in the case of a petrol-engined vehicle. Use is made of foolproof transistorized solid state circuits.
