How to dismantle the fire-fighting spray head without affecting other situations? Nozzle is not allowed to be installed in the machine room, and it should be removed or blocked.

It is impossible to dismantle it directly without going through the fire monitoring center. Whether the valve is closed or not, the fire monitoring center has a lot of information to display.

Moreover, there is a fire control law now. It is illegal to dismantle fire control facilities without permission, and you will be fined or imprisoned.

Therefore, if the nozzle is really unnecessary, it can be removed through normal procedures and replaced with gas to extinguish the fire.
