A main unit 1 is operable to arm and disarm a plurality of circuit breakers 2 which can immobilise the vehicle or operate a siren in response to an emergency situation such as unauthorised entry into or starting the vehicle. The circuit breakers 2 are programmable so as to be actuated at different times after the receipt of a signal indicating an unauthorised action. The circuit breakers 2 may control a fuel injection control circuit and a fuel pump power supply circuit and a siren or sirens may also be operated. A remote control key (30, figs. 9 and 10) may control the unit 1 and the breakers 2 by coded wireless links. <IMAGE> |
