<p>PURPOSE:To prevent generation of noise caused by unnecessary operation of sounding body by only having light of a light emitting body emitted at the detection of the first abnormality, and by operating the sounding body simultaneously with emission of light of the light emitting body when abnormality is detected in succession. CONSTITUTION:When an engine key is switched to the ON side of the ACC side at an input part 16, an alarming device becomes the OFF state by a reset circuit 17, and a light emitting body 2 and a sounding body 3 do not operate. On the other hand, when opening and closing of a door, vibration or sound is detected at sensors 1a-1c in the ON state of the alarming device by the engine key off, an operation control part 6 has only the light emitting body 2 emit light for a prescribed time in the first place. And when another abnormality detection signal is put in from the sensors 1a-1c through a sensor input part 5 in succession within a prescribed time, the operation control part 6 operates the sounding body 3, or the light emitting body 2 and the sounding body 3. In this way, generation of noise caused by unnecessary operation of the sound generating body is prevented, and effective alarm can be done by light and sound when an illegal act is continued.</p> |
