PURPOSE:To reduce a shock noise, by furnishing a converting relay between the sensitivity control switch of a shock absorber control unit and a burglar alarm device, and converting the relay to prepare a defending condition to perceive a shock while a high sensitivity adjustment is made. CONSTITUTION:The loading condition to a shock absorber control unit 19 can be converted freely to a high, medium, and low levels by a manual selection switch 21, and when it is at the medium or the low, the second relay 23 is at the normally closed position NC, and a burglar alarm control device 18 is off. When the unit 19 is converted to the high position in a parking or the like, and the shock signal from the shock absorber 20 is input, the second relay 23 is converted to the normally opened position NO, the burglar alarm device 18 is on, and a defending condition is prepared. Therefore, the burglar alarm control device 18 is off in the running condition or the like, to prevent the running shock from making the error operation of the alarm, while the burglar alarm control device 18 is secured to operate accurately at a parking or the like. |
