Is the voltage of fire shutter door 380V or 220V?

Is the voltage of fire shutter door 380V or 220V? Generally speaking, the voltage of domestic fire-resistant rolling shutter doors is 380V. There is no unified standard for the voltage of foreign fire-resistant rolling shutter doors. For example, the voltage in the United States is 110V, India is 420V, etc.

Does that mean that except for fire-proof rolling shutter doors, the voltage of other rolling shutter doors is 220V? The answer is also no. Let`s take wind-resistant rolling shutter doors as an example. The normal voltage is 220V, but if it exceeds 40 square meters, 380V voltage is required. I believe many factories will be equipped with 380V voltage. Therefore, it is recommended for customers who need to install rolling shutter doors. We should communicate with the manufacturer in advance about the voltage level and pull the wires in advance to facilitate the smooth installation of the rolling shutter door.
