PROBLEM TO BE SOLVED: To cause a disaster prevention device to be unnoticeable so that the appearance of a fitting face is inconspicuous at ordinary times, and cause the disaster device to operate effectively at an emergency time. SOLUTION: A recessed hole 2d is provided in a fitting face 2, so that the space inside and outside a room communicates mutually, an luminaire main body 3 is fitted so as to be near an embedding recessed hole 2d, and a smoke exhaust duct 1a as a disaster-prevention device 1 is connected to the outdoor side of the recessed hole 2d. The luminaire main body 3 is turned around a hinge portion 6 by a fire signal, and at least the other end side of the luminaire main body 3 is protruded from the recessed hole 2d, so that the recessed hole 2d functions as the smoke exhaust port 1c of the smoke exhaust duct 1a, and the smoke exhaust duct 1a, that is, the disaster device 1 operates. |
