M5 expansion screws are recommended for fastening, as shown in Fig. 2.

It shows the 'Waterproof box installation hole' spacing of 60mm, an internal dimension of 132mm, and a depth of 46mm. A separate view shows the 'Mounting surface' with a hole for an 'M5/M6 expansion screw' and 'Expansion pipe'.

2.2. Incoming Line Type

For the NFA-T02WB sounder strobe waterproof box, different construction types at the site may require different waterproof joints. The box can accommodate M20 and M36 waterproof joints. Details are as follows:

• M36 waterproof joint is standard, applicable to OD 18-25mm cable or conduit. It is recommended that the M36x1.5 waterproof joint thread length is 10mm.
• M20 waterproof joint is standard, applicable to OD 6-12mm cable or conduit. It is recommended that the M36x1.5 waterproof joint thread length is 10mm.

2.3. Optional Installation Principle for Fastening Screws

The upper cover and bottom case can be structurally clamped. During use, ST2.9*8mm self-tapping screws can be used to lock the bottom case to prevent accidental opening or human-induced protection failure due to the upper and lower covers not being tightly fastened, as shown in Fig. 4.
