GAS SHUT-OFF DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a gas shut-off device for preventing a wrong determination by previously setting the optimal battery voltage recognizing time and cycle. SOLUTION: A calendar means 15 sets the optimal driving cycle of a voltage detecting means 18 in a cycle setting means 16 to monitor the voltage of a battery power source means 2 in that time zone. Alarm display and an immediate shut-off based on the wrong determination that the battery is dead when a temporary voltage lowering due to a fluctuation of weather is detected can be thereby prevented.
