A security unit is to be fitted to a goods container to be secured, normally to the load doors, and will transmit a radio signal when it is interfered with to a radio receiver which gives the alarm. Where the container is part of or is loaded on a vehicle, then in addition to this security for the container itself, the alarm system will have to be immobilised by an authorised driver before the vehicle can be driven by inserting two different keys in a predetermined time sequence before the vehicle can be operated. |
