Claims

[Scope of Claim for Utility Model Registration] (1) A limit switch installed on the door of a fire extinguisher storage box is connected by a signal line to a controller that controls the opening and closing of a gas cutoff valve installed near the gas main valve, and the limit switch is installed on the door. A gas cutoff system configured to close the gas cutoff valve when detecting an opening of the door. (2) A limit switch installed in the fire extinguisher storage holder is connected with a signal line to a controller that controls the opening and closing of the gas cutoff valve installed near the gas main valve, and when the limit switch detects removal of the fire extinguisher, the gas shutoff is performed. A gas cutoff system configured to close a valve. (3) The limit switch is provided with a transmitter, and the controller is provided with a receiver, and when the limit switch is activated, a radio wave signal is transmitted from the transmitter to the receiver to activate the controller. The gas cutoff system according to claim 2 or 3, wherein the gas cutoff valve is configured to close. (4) A transmitter that activates when the safety pin of the fire extinguisher is pulled out is installed on the fire extinguisher side, and a receiver is installed on the controller side that controls the opening and closing of the gas cutoff valve installed near the gas main valve. The gas cutoff system is configured to transmit a radio wave signal from the transmitter to the receiver side to close the gas cutoff valve when the safety pin of the fire extinguisher is pulled out. (5) A gas cutoff system in which a changeover switch is added to the above limit switch so that the limit switch operation can be set to be disabled or enabled. (6) Connect an operation switch installed near the source of a gas range or other fire source with a signal line to a controller that controls the opening and closing of the gas cutoff valve installed near the gas main valve, and operate the operation switch to control the operation of the controller. A gas cutoff system configured to operate the gas cutoff valve and close the gas cutoff valve. (7) A transmitter is installed on the side of the operation switch installed close to the source of the fire such as a gas range, and a receiver is installed on the side of the controller that controls the opening and closing of the gas cutoff valve installed near the gas main valve. A gas cutoff system configured to operate a controller and close a gas cutoff valve by causing the transmitter to transmit a radio wave signal to the receiver side when a switch is operated.
