Title:
THERMAL FUSE TYPE SENSOR, FIRE PREVENTION ZONE FORMING DEVICE, AND FIRE PREVENTION ZONE FORMING METHOD
Document Type and Number:
Japanese Patent JP2022045222
Kind Code:
A
Abstract:
To cause an automatic closing device to be actuated by using a thermal fuse type sensor of a mechanical structure to the automatic closing device controlled electrically.SOLUTION: A fire shutter device 100 for executing automatic closing on the basis of an electric signal is caused to execute automatic closing by using a thermal fuse type sensor 11d of a mechanical structure. By mechanically moving a solenoid 126 held electrically according to the movement of a wire 11e in the fire shutter device 100 for executing automatic closing on the basis of an electric signal, the holding state is cancelled so that the fire shutter device 100 is automatically closed. Thus, an automatic closing device 12 can be actuated by applying the thermal fuse type sensor 11d of a mechanical structure to the automatic closing device 12 controlled electrically.SELECTED DRAWING: Figure 6
