In terms of speaker selection, according to the characteristics of the hotel, suspended ceiling speakers or wall-mounted speakers are mainly used in public places such as walkways; Waterproof ceiling speakers are installed in the bathroom of guest rooms, and horn speakers are mainly installed in the basement. The system usually plays background music, notifies and calls people, and also has the function of emergency broadcasting, which cooperates with the fire control system to implement zoning control.

The main functions of this system are:

1) background music:

Broadcast content can be extracted from audio sources such as radio stations, TV stations and CDs, and stones, stumps and mushroom-shaped speakers can be placed in public areas and green belts to play background music for a long time. In case of emergency broadcast, the system automatically skips the sound source selector and volume controller, and plays the emergency information at a larger volume.

2) Partition broadcasting:

Use the regional microphone and press the button of the corresponding region to broadcast to the region. At the same time, this broadcast mode also sends a strong signal. When an emergency (such as fire) occurs in a certain area, it is used to broadcast directionally to the area to coordinate and guide the crowd, so as to avoid broadcasting to the whole building area and causing excessive panic.

3) Automatic fire broadcast:

When the system receives the fire signal sent by the fire switchboard, it will play the pre-recorded emergency signal at a relatively large volume in the corresponding area; Because the system sends out a strong cut-off signal at the same time, even if the broadcast volume in the corresponding area is lowered or even turned off, it can be broadcast at a relatively large volume to ensure that people in this area can clearly hear the alarm signal.
