Abstract: A fire detector having a lifting function includes a fixed body fixed to a ceiling of a building, a lifting reel installed to the fixed body to vertically move a wire below the fixed body, and a fire detection unit connected to the wire below the lifting reel and installed to be vertically movable by the lifting reel. The lifting reel includes a drum connected with the wire to wind or unwind the wire by a motor, a lifting body positioned at a lower end of the fixed body and connected with the wire, and a contact terminal formed at an upper end of the lifting body. The contact terminal of the lifting body is contacted with a contact terminal formed at a lower end of the fixed body when the lifting body is completely ascended. The fire detection unit is fixed to the lifting body.
