に連結される。By the way, in recent years, in the construction industry, a beam member having a special unit structure is used for a ceiling of a high-rise building or the like to create a flat interior design with a small number of protrusions. ing. A metal beam called "T bar" is used for the beam member of the unit structure. Two "T-bars" are connected in an inverted T-shape with a space between them.

井の本来の思想に添わなくなるという不都合があった。A ceiling plate is placed on an outer protruding portion of the inverted T-shape of a plurality of beam members in which "T-bars" are connected in a pair structure, and a strip-shaped opening formed along the inner protruding portion. Is normally open and used for ventilation and ventilation. On the other hand, in the case of the above-described conventional fire detector in which the main body is attached to the ceiling surface by using the round hole, there is a disadvantage that the original idea of the system ceiling cannot be met.

とすると、システム天井の帯状の開口と試験器の円形の
開放面との間に大きな隙間が生じることになる。Therefore, the inventors of the present application have proceeded with the development of a box-shaped rectangular parallelepiped fire detector which can be directly attached to the belt-shaped opening of the system ceiling in place of the conventional cylindrical fire detector. However, if a conventional bowl-shaped fire tester is used to perform a warning test on such a box-shaped fire detector, a large gap is created between the belt-shaped opening on the system ceiling and the circular open surface of the tester. Will occur.

いという問題点があった。As a result, since the strip-shaped opening on the system ceiling is sometimes used for the air passage as described above, the generated pseudo smoke flows out together with the air flow in the air passage and is wasted. However, there is a problem that the test apparatus of 1 cannot be applied as it is.

The diameter of the opening 47 is made to be substantially in contact with the four apexes of the lower surface of the smoke absorbing portion 46, and the smoke absorbing portion 46 of the fire detector 40 can be covered without considering the direction of the opening 47. In this opening 47, the opening 47 protruding from the fire detector in the longitudinal direction of the fire detector is closed by the frame 23 of the mounting device 20, and the opening 47 protruding in the lateral direction of the fire detector is on the ceiling. Since it is blocked by the plate 9, the pseudo smoke generated from the tester does not flow out to the strip-shaped opening of the system ceiling,
Can flow into a fire detector. Although the circular opening 47 is shown in the embodiment, it may be elliptical.
