Abstract

The alarm system has an audio alarm (1) e.g. the vehicle horn, operated via a relay (3) in response to closure of any of the alarm contacts (9). The circuit also includes a cyclic switch (10) which is stepped by each pulse received by the switch coil (11) through a number of states, before returning to its original condition, only one of these stages causing the switch contact to open. A magnetic reed switch (22) is also included and is operated by bringing a magnet into proximity to it, with the magnet also used to operate a further reed switch (31) in parallel with the alarm release circuit. Pref. the magnet is incorporated in a door key for the vehicle.
