According to the fire alarm receiver 100, the door 20 that closes the opening 11 of the housing 10 and the substrates 70 and 80 provided on the housing 10 side are provided substantially parallel to each other. Moreover, the substrate 70 and the substrate 80 are provided with a space therebetween. Further, since at least a part of the substrate 70 and at least a part of the substrate 80 overlap each other in the direction orthogonal to the direction of the substrate 70, a fire receiver having two substrates in the housing 10 can receive a fire signal. The installation area of the machine 100 can be made more compact than when the two substrates are provided side by side on the same plane. Then, as an example, the substrate 70 and the substrate 80 are arranged so as to be slightly deviated from each other. This is for facilitating the work of connecting the electric wire from the lead-in port 19 formed in a tubular shape to the terminal block (not shown).

Further, according to the fire receiver 100, since the end portion 31 of the board mounting plate 30 is connected to the fixed portion 50 through the hinge 35, the setting of the boards 80 and 70a, the wiring work or the maintenance inspection. When the board mounting plate 30 is removed, the board mounting plate 30 is removed from the board holding portion 60 and the board mounting plate 30 is rotated.
The setting of the boards 80 and 70a, the wiring work, and the maintenance and inspection can be easily performed.

According to the fire receiver 100, the housing 1
Since the space SP1 and the space SP2 exist on the inner wall 14 side and the inner wall 15 side that are the periphery of the housing 10 from the substrate 70 and the substrate 80 in 0, the wiring to the substrates 70a and 80 is performed by the space S
Wiring to the substrate 70 can be performed using P1.
Since it can be performed using the space SP2 and an electric wire (not shown) can be easily routed, wiring to the substrates 70, 70a, 80 is facilitated.

Further, according to the fire alarm receiver 100, the packing 23 is provided, and when the door 20 is closed, the peripheral edge 17 of the opening of the housing 10 is fixed to the door 20 so as to crush the packing 23. Since the hinge 24 and the tongue piece 91 are urged,
When the fire receiver 100 is installed in an environment where water is splashed, such as a ship, it is possible to prevent water from entering the fire receiver 100 through the gap between the peripheral edge 17 of the opening of the housing 10 and the door 20. . At this time, of course, it is more effective if the housing 10 is configured compactly and the size of the opening is small.

At this time, since the hinge 24 connects the outside of the peripheral edge 17 of the housing 10 and the outside of the peripheral edge 22 of the door 20, the entire surface of the packing 23 can be pushed with the hinge 24 as a fulcrum.

Although the fire receiver 100 is provided with three substrates, the above embodiment can be applied to a case where four or more substrates are provided in the fire receiver.
