#Elevator-ARD-manufacturers #Elevator-Control-Panel-manufacturers #Pixel-Control Elevator ARD, which stands for Automatic Rescue Device, is used in elevators to ensure the safety of passengers in case of power failures or other emergencies. It is a safety feature that is required by many building codes and regulations. In the event of a power failure or other emergency that causes the elevator to stop between floors, the ARD activates and brings the elevator to the nearest floor where passengers can safely exit. The ARD is designed to detect when the elevator has stopped between floors and then automatically switch the elevator to an alternate power supply, such as a battery or generator, to allow the elevator to return to a floor where passengers can exit. The use of an ARD is important because it can help to prevent passengers from becoming trapped in an elevator during a power failure or other emergency. Elevators are often used in high-rise buildings and other settings where evacuation via stairs may not be practical or safe, so the ARD provides an added layer of safety and security for passengers.
