Abstract
An alarm unit is provided which prevents a theft of a vehicle by producing acoustical alarm whenever a third party opens a door of the vehicle. The unit operates by applying a remote control signal from an external signal emitter to a pickup assembly which is mounted inside the vehicle on a front or a rear glass pane. A control circuit connected to the pickup assembly is then set in its standby mode, and conditions the unit to produce an acoustical alarm if the door is opened during such mode. The standby mode is reset by a second application of the remote control signal to the pickup assembly.
