It mainly talks about the wiring installation process in line with the decoration progress.
1. Wiring, speaker line layout is best done together with the electrician’s wiring, but the speaker wire is weak current, so it should not be too close to the electrician’s strong current (AC220V). If it is worn through PVC pipes, the distance should be 20 Centimeters is enough. This should be done due to factors such as installation and interference, but the overall wiring route should try to follow the strong or weak current lines laid out by the electrician. It will not appear cluttered and will be convenient for future maintenance because the electrician wires the wiring. Generally, there will be an inspection opening, and the speaker wires should be distinguished from other lines. Don't not know which speaker wire is which when you perform maintenance in the future. The PVC pipe of the speaker line can be fixed on the ceiling hanging rod. Another thing that needs to be cooperated with the electrician is that the position of the speaker point also needs to take into account the position of various lights, the position of the fire sprinkler head, and the outlet of the air conditioner during the actual construction process. The air outlet, the shape of the ceiling cap, etc. If your speaker is installed in the same position as the lamp, or is designed at the air outlet of the air conditioner, it is not good and will affect the appearance.
When the speaker cables pass through PVC pipes, we require that the PVC pipes do not use elbows, but use springs to bend them to ensure that the wires in each pipe can twitch freely from the junction box. This is mainly to ensure that Later repairs and replacement and threading will be done.
2. Precautions for opening holes for speakers. Use a special hole opener and do not damage the ceiling, especially the ceiling with gypsum suspended ceiling.
The diameter of the opening should be according to the opening size specified for each speaker. In actual construction, it can be slightly larger, so that installation and removal are easier, especially for gypsum ceilings. If the speakers are installed very tightly, they need to be removed. It's easy to damage drywall when you put it down.
3. When installing ceiling speakers, it is best to wait until the painter finishes painting and then install them carefully. Electricians usually install various lights at this time.
In short, these processes need to be well coordinated with other types of work on site. You cannot just take into account your own progress, but you must often communicate and learn from them.
