Before the fire acceptance, the shop will make a ceiling, will it affect the fire acceptance?

This needs to be determined according to the nature of the building and the fire resistance level of the building, four types of buildings are OK, three types of buildings are required to carry out fire treatment, and Class 2 and Class 1 buildings are not allowed.

This depends on what style the ceiling is, the closed ceiling should be led down, if the grille ceiling does not have to be introduced, that is, the smoke can naturally spread to the upper part of the ceiling, you can not lead down.

If the kitchen is relatively closed, that is, except for their own employees, others can hardly see inside, then you can do without the ceiling, save some money, but the hall is to do, or the fire protection device is not easy to hide, one is not good-looking, and the two are easy to damage. >>>More

First, you are right, if you remove the ceiling, your sprinkler head must be changed to spray upward, and the smoke detector must also be adjusted to the ceiling, and it costs money to change this sprinkler head; Second, "must be changed", this question is difficult to answer, anyway, the norm is not allowed; It is not allowed by the local fire department; I'm afraid the property won't allow it, and your neighbors won't allow it if they know it; It is also not allowed from a practical security point of view. If you can balance the above factors, then there is no problem, you can not change it. 3. If it is a formal procedure, before the fire protection system is changed, the modification plan issued by the unit with design data must be submitted to the fire bureau for approval, and you can only modify it after approval and approval.

This has little to do with firefighting.

The main consideration is electrical safety. >>>More
