Automatic Rescue Device (ARD)

Elevator emergency automatic rescue device (also known as ARD) is a special device installed in an elevator which is only used during an event of a power failure or blackout in a building.

An elevator emergency landing device is useful for preventing passengers from becoming trapped inside an elevator during a power failure Upon power failure, an elevator equipped with this device automatically moves and stops at the nearest floor using a rechargeable battery (or uninterruptible power supply also known as a UPS), and the doors will then open to ensure any onboard passengers’ safety
