Lift ARD & UPS

Let’s delve into the roles of ARD (Automatic Rescue Device) and UPS (Uninterruptible Power Supply) in elevator systems:

• Purpose: The ARD is a critical safety feature in elevators. Its primary purpose is to ensure passenger safety during power outages or emergencies.
• Functionality:
  • When the main power supply fails, the ARD activates automatically. It powers the elevator’s emergency lighting, ventilation, and communication systems.
  • The ARD moves the elevator car to the nearest floor and opens the doors, allowing passengers to exit safely.
  • It prevents passengers from being trapped between floors during power failures.
• Importance: The ARD significantly enhances passenger confidence and safety, especially in high-rise buildings.
