[0031] The linear installation groove 204 is opened at a position near the top on the outside of the fixed cover 201. The linear through - groove 205 is opened at the top outer wall of the fixed cover 201 and is in communication with the linear installation groove 204, and two linear through - grooves 205 correspond to a single linear installation groove 204;

[0032] The bent pieces 207 are symmetrically fixed to the top of the connecting piece 206. The connecting piece 206 is slidably clamped inside the linear installation groove 204, and the two bent pieces 207 respectively extend above the top of the fixed cover 201 through the two linear through - grooves 205;

[0033] By bending and sleeving the two bent pieces 207 on the outside of the lower surface of the T - shaped keel of the gypsum board ceiling, it is used to realize the installation and fixation of the fixed cover 201 on the gypsum board ceiling;

[0034] Four linear installation grooves 204 are provided. The four linear installation grooves 204 are circumferentially and evenly distributed with the center of the fixed cover 201 as the center.

[0037] This wireless smoke detector 1 has three installation methods, and the specific installation operations are as follows:

[0038] The first is the adhesive fixation method. Just attach the adhesive sticker to the upper surface of the fixing cover 201. Then, bond the fixing cover 201 to the installation position through the adhesive sticker. Finally, snap the wireless smoke detector 1 with the arc L-shaped card slot 104 and the arc L-shaped buckle 203. This installation method is suitable for installation on smooth surfaces, such as ceramic tile walls and latex paint walls;

[0039] The second is screw installation and fixation. Corresponding holes can be drilled at the installation position according to the position of the straight slot 202. Then, insert an expansion tube into the hole. Next, fit the fixing cover 201 to the installation surface and tighten the screw through the straight slot 202 and thread it with the expansion tube. Finally, connect the wireless smoke detector 1 to the fixing cover 201. This installation method is suitable for installation on concrete walls;
