PROBLEM TO BE SOLVED: To provide an attaching device for an exclusion cover of smoke fire detector which can safely and easily attach and remove the exclusion cover when the action of the detector arranged in a high place is cut off. SOLUTION: This device has an engage pin 10 which sticks out from a cover part which covers a detector 14 to cut off the action of the detector, an exclusion cover 1 which is equipped with a felt 3 which is fixed on a inner peripheral surface of the cover and elastically attached on an outer peripheral surface 15 of the detector 14, an attaching jig 11 which has a shaft direction groove 12a where the connection pin 10 can be penetrated and a rotation direction groove 12b which is releasably connected and a long operation rod of which the attaching device 11 is connected. The operation rod 17 is operated upward while the engage pin 10 is inserted inside the rotation direction groove 12b, the detector 14 is pushed into the exclusion cover 1 and fastens the exclusion cover. By inversely rotating and operating downward the operation rod 17, the connection pin 10 is pulled out from the rotation direction groove 12b and the shaft direction groove 12a and a connection of the exclusion cover 1 and the attaching jig 11 is released. |
