PURPOSE:To maximumly exhibit the burglarproof function of a device for delivering a warning output when a door is opened, by providing such an arrangement that the establishment of a warning circuit in a monitoring set condition is related to a brake operation before the time of getting-off of the driver. CONSTITUTION:A relay H is energized in association with such a condition that the driver depresses a brake pedal and then gets off a vehicle through the opened driver's seat door, and when a relay switch h1 in the relay H is turned on and a relay switch St2 in a relay ST is turned off, the short-circuit of a relay B is established. When the relay B is then turned off to establish a discharge circuit of capacitors C1, C2, C3 (so that a relay P for energizing a warning circuit becomes possible to operate), a monitoring set condition may be created. The relay P for the warning circuit, is energized when either one of door switches DS1 through DS4 is turned on, and therefore, turns on a relay switch P2 thereof to sound a horn speaker SP.
