It is a safety feature that is designed to automatically rescue passengers in the event of a power failure or other emergency situation. During normal operation, elevators rely on electrical power to operate the motor that moves the elevator car. However, in the event of a power failure, the elevator ARD kicks in to ensure that passengers are not trapped inside the elevator car. The Automatic Rescue Device typically includes a backup power source, such as a battery or an uninterruptible power supply (UPS), that provides temporary power to operate the elevator's essential functions, such as the control system, lighting, ventilation, and communication devices. This allows the elevator to safely move to the nearest floor and open its doors, allowing passengers to exit the elevator car and safely leave the elevator.
