The alarm device is made active when the key switch is in the stop position. The sensor comprises a mercury ball in a spherical hollow suspended from a pendulum to ensure it is initially vertical. It closes a contact (11), when tilted or accelerated. A delay circuit (30,31,32,37) is connected to a relay (33,41) to initiate the device after a delay. A second relay (12,13,14) is closed, setting off the alarm (5), until the circuit is initiated. In addition, a third relay (16,26) operates cutting off the supply from the battery to the electrical circuits and a square wave generator (24) alternately lights and extinguishes the indicator lamps (CG,CD). |
