Using partition multiple amplifier system, improve system reliability and reduce the proportion of backup power amplifier. The use of advanced digital sound processing technology, according to the specific conditions for the construction of the appropriate regulatory treatment in order to obtain high-quality voice clarity and smooth.
If there is fire, according to fire partitions select broadcast Division, in broadcasting the main switch, break in through broadcast, go to the fire radio broadcasting State.
Fire alarm component requirements
1. two-tier and second-tier above floor there is a fire, should in this layer and the adjacent layer; the first floor there is a fire, should in this layer, Layer II and underground floors for broadcasting; fire in the underground, underground floors and broadcast for the first layer.
2. fire occurs should be able to fire control room will fire evacuation layer of broadcasting system forced into emergency broadcast status, show floor; and can be realized manual and automatic.
3. some parts of the building in addition to the emergency broadcast, in the absence of emergency broadcast of its public areas usually can play background music.
The speaker distribution design
According to the specifications, the regional allocation should first meet fire broadcasting zoning requirements. According to the design requirements, XX XX general merchandise store background sound system is divided into eight broadcasting area, Office area for 9. Microphone voice free choice on the circuit, or individual, or group, or to broadcast all calls without affecting other circuit of a normal radio.
8 region contains background music system and fire broadcasting system, both systems into one, share the same power amplifier. The speakers were in peacetime, music plays in the State of emergency will automatically switch to the emergency broadcast.
The speaker distribution design basic requirements analysis
Sound system front-end design must consider the following factors:
Surrounding noise: noise environment, system front-end necessary sound pressure.
Echo: the echo effect around the walls, etc., systems of sound clarity must be considered.
Purpose: the purpose and must, accordingly, to a reasonable configuration front-end.
The necessary sound pressure
Output sound pressure:
Generally, the loudspeaker output sound pressure and Horn rated output according to different occasions with some differences, the ordinary occasions rated output power of the loudspeaker output sound pressure generally should have increased from 5 to 10dB.
So according to the above points, XX department store front speaker output sound pressure requirements should be around 70 to 90dB can guarantee better results. 3W speakers generally output sound pressure in 90 to 100, coupled with the increase in ordinary occasions about sound pressure, the Horn around 7dB installation distance in between 6 to 10 meters will be able to meet the requirements, achieve better results, so we used the arcade 3W speakers, spacing 8 meters installed, guarantees that the output of the above 85dB sound pressure, so that the building personnel in any location can be clear to tune into radio and music.
According to the above and the actual use of the request, we will use Japan Panasonic speakers to meet technical requirements.
