Title:
THERMAL FUSE TYPE SENSING DEVICE, FIRE PREVENTION EQUIPMENT CONTROL SYSTEM, FIRE PREVENTION SIGNAL TRANSMISSION METHOD, AND FIRE COMPARTMENT FORMING DEVICE
Document Type and Number:
Japanese Patent JP2022024821
Kind Code:
A
Abstract:
To output an electrical sensing signal using a thermal fuse.SOLUTION: A thermal fuse 107 blows under a certain condition. A cosmetic cover 104, a reset lever 106, etc. are provided as movable means that is mechanically moved by the blowing of the thermal fuse 107. Switching means (a microswitch 112) is provided to change a setting state to on state or off state in conjunction with the movement of the movable means. By electrically detecting the on state or off state of the switching means, the blown thermal fuse 107 can be detected as an electrical signal. A thermal fuse type sensing device will output an electrical sensing signal when the thermal fuse blows. This thermal fuse type sensing device is used to configure a fire protection equipment control system, a fire prevention signal transmission method, and a fire compartment forming device.SELECTED DRAWING: Figure 4
