Power failures can happen unexpectedly, but getting trapped inside an elevator shouldn’t be one of the risks. This is where an Automatic Rescue Device (ARD) plays a vital role. Modern elevators include advanced safety systems, and the Automatic Rescue Device (ARD) plays a vital role in protecting passengers during a power outage.
In this guide, you’ll learn what an Automatic Rescue Device is, how it works, its benefits, and why it has become an essential safety feature in residential, commercial, and industrial elevators.
What is an Automatic Rescue Device (ARD)?
An Automatic Rescue Device (ARD) is an emergency backup system installed in an elevator that automatically moves the lift to the nearest floor during a power failure. Once the elevator reaches a safe landing, the doors open automatically, allowing passengers to exit safely.
Instead of leaving passengers stranded between floors, the ARD temporarily powers the elevator using a backup battery or stored electrical energy until the rescue process is complete.
Why is an ARD Important?
Without an ARD, a sudden power interruption can stop an elevator between floors, requiring passengers to wait for trained technicians to perform a manual rescue.
An ARD helps eliminate this situation by automatically bringing the elevator to a safe landing, reducing stress and improving passenger safety.
It is particularly valuable in:
- Residential Apartments
- Hospitals
- Shopping Malls
- Hotels
- Office Buildings
- Educational Institutions
- Commercial Complexes
How Does an Automatic Rescue Device Work?
The operation of an ARD is quick and fully automatic.
Step 1: Power Failure Detection
- The system continuously monitors the main power supply. If electricity is interrupted, the ARD immediately detects the outage.
Step 2: Backup Power Activation
- The ARD switches to its built-in battery backup or emergency power source without requiring any manual intervention.
3rd Step: Elevator Movement
- Using the available backup power, the controller moves the elevator slowly to the nearest landing floor.
Step 4: Door Opening
- After reaching the landing, the elevator doors automatically open, allowing passengers to leave safely.
Step 5: Normal Operation Resumes
- Once the main power supply is restored, the elevator automatically returns to normal operating mode after completing the necessary system checks.
Key Benefits of an ARD
Installing an Automatic Rescue Device offers several advantages.
Improved Passenger Safety
- Passengers can safely exit the elevator instead of remaining trapped during a power outage.
Automatic Operation
- The rescue process starts automatically without requiring assistance from maintenance personnel.
Reduced Panic
- Knowing the elevator will reach the nearest floor helps reduce anxiety during unexpected power failures.
Better Reliability
- The elevator remains safer and more dependable during emergency situations.
Suitable for Various Buildings
- ARD systems are beneficial for residential, commercial, healthcare, and industrial buildings.
Components of an ARD System
A typical Automatic Rescue Device consists of:
- Backup Battery
- Intelligent Control Unit
- Battery Charger
- Power Switching Circuit
- Monitoring System
- Safety Controller
These components work together to ensure the elevator performs a safe emergency landing whenever required.
Is an ARD Mandatory?
Building regulations and elevator safety requirements vary depending on local authorities and applicable standards. However, many modern elevator installations include an ARD because it significantly enhances passenger safety and provides greater confidence during power interruptions.
For new residential and commercial projects, an ARD is widely considered a highly recommended safety feature.
Maintenance of an Automatic Rescue Device
Like any safety equipment, an ARD should be inspected regularly to ensure it functions correctly when needed.
Routine maintenance typically includes:
- Battery health inspection
- Backup power testing
- Controller diagnostics
- Emergency operation testing
- Electrical connection checks
Regular servicing helps ensure reliable performance throughout the life of the elevator.
