How to spray the hotel lobby when the height of a single floor exceeds 10 meter?

1. The specification clearly points out that there is no need for automatic sprinkler systems in tall spaces with a building height of more than 8 meters. But now many projects are equipped with water cannon rapid reaction nozzles or self-spraying systems according to specific conditions. Whether the hotel lobby is set up needs specific analysis: mainly whether there are many combustibles. It is speculated that the hotel lobby is crowded with people and there are many combustibles, and the accommodation registration office and rest place are generally not located in tall spaces, so the automatic sprinkler system can be omitted. Consider setting up rain or fire monitors and intelligent active sprinkler systems in large spaces.

2. In some places, the nozzle is hung below 8m, and the nozzle is treated with a heat collecting cover.
