Network ceiling speaker function and application

IP Network Ceiling Speaker - Ceiling Speaker Speaker

Ceiling speaker speaker installation method and wiring need to know, for project engineering customers to provide reference

1, the speaker line layout is best done with electrical wiring together, but the speaker cable is weak, should be with the electrician's strong electricity (AC220V) do not rely too close, wear PVC pipe, distance 20 cm on it, for the 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 obvious 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 horn mounting position and lamp position repeat, or designed in the air conditioning outlet, not always 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 thread 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, ceiling speaker ceiling speaker ceiling speaker installation method, it is best to wait for the painter to complete the paint, be careful to install up, usually the electrician is also the installation of various lights at this time. 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.

IP Network Ceiling Speaker - Ceiling Speaker Speaker

IP Network Ceiling Speaker Features:

One-way terminal, digital decoding terminal and ceiling speaker integrated, power 2 * 6W, POE power supply, just connect a cable, no external power supply , wiring is simple.

Compatible with external DC12V power supply. When there is no POE power supply environment, external power supply can be used.

IP Network Ceiling Speaker Function Description

u support network real-time playback;

u support network timing playback;

u Supports unicast and multicast functions;

u support is paged to receive broadcasts initiated by other terminals in the system;

u support terminal program remote online upgrade;

u supports cross-network segment and cross-route, as the Internet terminal of the wide area network, supports DHCP;

u Support self-adaptive network environment. When network conditions are poor, buffering and packet loss retransmission can be initiated.

u expansion interface, short-circuit input, controllable 5V/6mA power output interface, can be extended to a key call and call status indication.
