Ceiling speaker installation method

The ceiling speaker, also known as the ceiling speaker, is an important member of the public address system. It is an electro-acoustic conversion device mounted on the ceiling. It is used to convert the audio electric power signal input from the amplifier into a sound power signal and radiate sound waves to the space where sound is needed. It is generally used in public places, input audio power signal in constant pressure mode, and there is also space where there is not much space, and the signal is transmitted in a constant resistance manner.
Ceiling speakers are widely used in guests, hotels, factories, schools, shopping malls, supermarkets, clubs, villas and other places, as background music, fire radio, paging radio, public broadcasting and other sound reduction equipment.


installation method
Wiring, horn line layout is best done with electrical wiring, but the speaker cable is weak, should not be too close to the electrician's strong power (AC220V), wear PVC pipe, distance 20 cm on it, for installation and Interference and other factors are due to do so, but the total walking line should be as far as possible to follow the electric or weak circuit lines arranged by the electrician, not significant clutter, and later overhaul is also convenient, because the electric wiring will generally leave the access port, speaker cable To distinguish it from other lines, do not know which one is the speaker line when you do not go overhaul later. The horn cable PVC pipe can be fixed on the ceiling ribs. There is one thing that needs to be coordinated with the electrician is that the location of the horn point in the actual construction process also need to take into account the location of various lights, fire sprinkler position, air conditioning out The tuyere, as well as the shape of the ceiling cap, etc., if your speaker installation position and lamp position repeat, or designed in the air conditioning outlet, the total is not good, but also affect the appearance. The speaker cable is threaded through the PVC pipe. We require that the PVC pipe does not use elbows but use spring bending to ensure that the wire inside each pipe can be freely twitched from the junction box. The main reason is to ensure the maintenance and change of threads and threading. . 2. Notes on the opening of the horn, use a special hole opener, do not damage the ceiling, especially the ceiling of the plaster ceiling. The diameter of the opening is in accordance with the opening size specified for each speaker. In actual construction, it can be slightly larger, which makes installation and removal easier. Especially for plaster ceilings, if the speaker is installed tightly, it is easy to remove the plaster when it is removed. board. 3, the installation of ceiling speakers, the best painter to complete the paint, be careful to install up, usually the electrician is also installed at this time a variety of lights. In short, these processes need to be coordinated with other types of work on the spot. They can't only consider their own progress and should communicate and learn with them frequently.
The last thing to note is that the system must be checked before the system is turned on. Of course, this work should be checked before the line is laid out (sealing the ceiling).
