Abstract
PURPOSE: To surely give an alarm without special operation when a door is opened, by providing a starting switch with a contact which is closed when a key is pulled out and by driving an alarm relay through a capacitor charged through the closed contact.
CONSTITUTION: When a key is pulled out, a contact 1 is closed and the charging of a capacitor 3 is started through a resistor 2. The time constant in that case is set at about two seconds or the like. A door switch 8 is closed when a door is open. Normally open contacts 5W7 are closed when a coil 4 is energized. The capacitor 3 is charged and a waiting state is when all the doors are closed within two seconds after the pulling-out of the key by the driver. When a door is opened and the door switch 8 is closed, the coil 4 is energized and the contacts 5W7 are closed. At that time, an antitheft buzzer 9 starts sounding. The buzzer 9 contiunes to sound until the contact 1 is opened.
