The following are some key steps and points about how to link the community broadcast with the fire fighting system:

Linkage signal design: The linkage trigger signal of the fire fighting emergency broadcast system should adopt the AND logic combination of the alarm signals of two independent alarm trigger devices. This means that the alarm signal of two independent fire detectors or a fire detector and a manual fire alarm button in the fire protection zone will be used as the linkage trigger signal of fire emergency broadcast. This signal should be sent by the fire-fighting linkage controller, and the fire-fighting linkage controller or the broadcast partition controller controls the opening of the emergency broadcast.

broadcast system design: the community broadcast system needs an emergency broadcast sound source device, which is used as a forced program source to input to the matrix control host of the public broadcast system. In this way, in an emergency, the fire broadcast can be broadcast in different areas as required.

manual and automatic start: the fire broadcast system can be started manually or automatically. When starting manually, you can directly start the broadcast of a certain floor through the buttons on the relevant floor of the bus panel. When it is started automatically, after the fire detector or manual alarm button sends out an alarm signal, the fire linkage controller will send out a linkage trigger signal to start the fire emergency broadcasting system.

speaker circuit design: the speaker circuit of the fire-fighting broadcasting system should use fire-resistant wires to ensure that the broadcasting system can still work normally in case of fire. As a speaker circuit for general background music broadcasting, ordinary flame-retardant wires can be used.

broadcast content: in the community broadcast system, fire risk warnings can be played circularly during commuting and business peak hours, such as instructing people how to use fire extinguishers correctly to put out initial fires, and reminding people not to park electric bicycles or charge them indoors or in the stairwell.

please note that the above information is for reference only, and the specific implementation may be different due to the specific situation and equipment of the community. In actual operation, it is suggested to operate according to the relevant fire protection specifications and equipment instructions to ensure the normal operation and effectiveness of the system.
