Is there a power in the fire elevator when there is a fire?
However, this kind of elevator is not designed in accordance with fire standard, and the fire resistance time is shorter. The main difference is that the engine room does not have higher fire resistance time to the engine room of the fire elevator. At the same time, the fire elevator is protected by double power supply. When a power supply is burnt down, there is a power supply. The ordinary elevator usually has only one power supply, if burned, there is no standby power supply.No matter whether it is a fire elevator, its power supply will not be cut off during the fire (except for the malfunction).
In fact, the ordinary elevator is also a fire control button, firefighters can also break the elevator hall door on the glass broken switch, press the fire control button can use. As a standby for fire elevator. The elevator door base you can in any building (or left) from the door within 30 cm, 1.5 meters from the ground more than 2 meters (usually 1.8 meters) position to see a broken switch, and marked with the fire button ".
After the fire elevator reaches the base level, it can still continue to operate. The firemen just need to smash the breaker on the door of the elevator hall and press the fire control button to use it.
In the event of a fire, the elevator is more than just a fire lift. It has electricity.All elevators will be automatically lowered to the base level (usually one floor) after receiving the fire signal, and will rise to the base level in the basement.After the ordinary elevator reaches the base level, opens the elevator door and stops running, but then the elevator is still power.
