Can Installing an Elevator ARD (Automatic Rescue Device) Really Save People During a Power Outage?
In high-rise urban buildings, elevators have become an indispensable vertical transportation tool. However, regardless of how advanced the elevator brand or system is, power outages remain one of the most unavoidable sudden situations. Many users worry: “If I encounter a sudden power outage while in the elevator, will I be trapped?”
Because of this concern, more and more properties choose to install Elevator Automatic Rescue Devices (ARD) to enhance elevator safety.
But can an ARD really “rescue people” during a power outage? How does it work?
Today, the technical team from A-FLY Elevator & Escalator Parts Supplier will answer all your questions.
1. What Is an ARD Automatic Rescue Device?
ARD (Automatic Rescue Device) is an auxiliary rescue system that activates when the elevator suddenly loses power, when the main power fails, or when an emergency stop occurs. When the elevator loses its main power, the ARD immediately takes over the power supply, allowing the elevator to operate at low speed to the nearest floor and automatically open the door so passengers can exit safely.
Simply put:
An ARD is not designed to let the elevator continue normal operation, but to allow passengers to exit safely.
2. Can an ARD Really Save People During a Power Outage?
The answer is: Yes, and it is very reliable.
When the elevator suddenly loses power, the ARD automatically works and performs the following steps:
1. Automatically detects “power loss”
The system instantly determines if the main power has been cut, preventing the cabin from staying dark and still for too long.
2. Activates backup batteries or UPS system
The internal battery pack supplies enough power to maintain:
- Low-speed host operation
- Basic control system functions
- Elevator lighting
- Door operator movement
Passengers will not experience darkness, panic, or lack of air.
3. Elevator moves at low speed to the nearest floor
The ARD does not allow the elevator to continue normal service. Instead, it moves the elevator safely and slowly to the nearest landing level.
4. Automatically opens the door for safe exit
Once the elevator is level, the doors open automatically so passengers can exit quickly.
The entire process usually takes 30–60 seconds.
3. In What Situations Can an ARD Rescue People?
ARD is designed to handle emergency situations such as:
- Sudden loss of city power
- Transformer failure
- Elevator main power tripping
- Emergency shutdown due to electrical component short circuits
- Temporary power interruption caused by thunderstorms
In simple terms, as long as the elevator loses main power, the ARD will function.
4. What Can’t an ARD Do?
To avoid misunderstanding, let’s clarify:
An ARD is not a backup generator and not a long-term power supply for elevator operation.
It cannot:
- Maintain normal elevator operation
- Provide long-term power
- Replace the elevator’s main driving power
Its only function is to allow passengers to exit safely.
5. Why Is It Necessary to Install an ARD?
1. Prevent passenger panic
Many people are afraid of being trapped in an elevator. ARD minimizes this risk.
2. Improve building safety standards
High-end residences, commercial centers, and hospitals almost always include ARD as standard.
3. Protect vulnerable passengers
Elderly individuals, children, and pregnant women are especially prone to panic during power outages.
4. Prevent equipment damage when power is lost
Stopping at a floor level is far safer than being stuck in the shaft.
