One of the most common questions when considering or installing an automatic door system is: Can automatic doors be opened during a power outage? Many people worry that when the power goes out, the door may become locked shut, disrupting traffic flow or preventing safe evacuation in an emergency. In reality, modern automatic door systems are designed with multiple backup mechanisms to ensure users can continue entering and exiting safely even when the power supply is interrupted. So, how do automatic doors operate during a power outage? What options are available for opening the door, and what should be considered to ensure the system remains safe and reliable? Let’s explore the details with Sonha Auto.
Can automatic doors be opened during a power outage?
The answer is YES.
Most modern automatic door systems are designed to allow users to open the door even when the power is out. This is an important safety requirement to ensure that people, goods, and equipment can continue moving through a building without interruption.
Depending on the door type and system configuration, the door may be opened in several ways:
- Manual opening through a mechanical clutch mechanism.
- Continued operation using a UPS (Uninterruptible Power Supply) or backup battery.
- Automatic release of electric locks in systems equipped with fail-safe locking devices.
- Automatic opening to a predefined safe position during emergencies.
Therefore, if you are wondering, “Can automatic doors be opened during a power outage?”, the answer is absolutely yes, provided that the system has been properly designed and installed according to technical standards.
Why can automatic doors still be opened during a power outage?
Many people assume that automatic doors rely entirely on electricity and therefore become unusable when power is lost. However, the reality is quite the opposite.
Modern automatic door systems are designed with safety and emergency egress as top priorities. During product development, manufacturers incorporate features such as manual opening mechanisms, backup power systems, and automatic lock-release functions to ensure continued accessibility during power interruptions.
This is one reason why automatic doors are widely used in hospitals, airports, shopping malls, hotels, railway stations, and other public facilities with high pedestrian traffic.
Methods for opening automatic doors during a power outage
Manual opening via the clutch mechanism
Many users ask whether automatic doors can be opened manually during a power outage. The answer is yes.
Many automatic door systems are equipped with a clutch mechanism integrated into the motor or drive unit, allowing the system to switch to manual operation. Once the clutch is released, the door can be pushed or pulled just like a conventional door.
Advantages of this solution include:
- No dependence on electrical power.
- Easy operation.
- Reliable performance even during prolonged power outages.
Using a UPS or backup battery
Many automatic door systems are equipped with a UPS or backup battery system. When the main power supply is interrupted, the backup system automatically provides power to the controller and motor, allowing the door to continue operating for a specified period.
Depending on the system configuration, the door may:
- Continue operating normally.
- Perform multiple additional opening and closing cycles.
- Automatically open to a safe position.
- Maintain access control functionality for a limited period.
This solution is commonly used in hospitals, airports, shopping centers, and facilities requiring continuous operation.
Automatic lock release during a power outage
Some automatic doors are integrated with electromagnetic locks or access control systems. In these cases, many facilities use fail-safe locks, which automatically unlock when power is lost.
The operating principle is as follows:
- When power is available, the lock remains engaged.
- When power is lost, the lock automatically releases.
- Users can push the door open and exit safely.
This solution helps ensure safe evacuation during emergencies.
How do NABCO automatic doors operate during a power outage?
When considering Can automatic doors be opened during a power outage?, many building owners are particularly interested in the performance of NABCO automatic door systems when power is interrupted. As a leading Japanese automatic door brand, NABCO designs its products with safety and operational continuity as key priorities. Power outage scenarios are considered from the earliest stages of product development.
Easy manual operation during power outages
One common concern is whether NABCO doors become locked shut during a power outage. In reality, NABCO automatic sliding doors are designed to allow manual opening when power is unavailable. According to the manufacturer’s specifications, many NABCO models can be manually operated with an opening force of less than 100N (approximately 10.2 kgf).
This means users can easily push or pull the door without special equipment. This capability is especially important in hospitals, airports, shopping malls, and railway stations where uninterrupted movement of people and equipment is essential.
Mechanical key system for operation and maintenance
In addition to manual operation, each NABCO automatic door system is supplied with a dedicated mechanical key. This mechanical key allows technicians or facility operators to switch operating modes, perform inspections, carry out maintenance, and troubleshoot the system when necessary. As a result, door operation during power outages and maintenance activities becomes safer and more convenient.
Optional UPS integration
For facilities requiring uninterrupted operation, NABCO door systems can be equipped with a UPS. During a power outage, the UPS supplies backup power, allowing the door to continue operating for a certain period. This minimizes disruptions and maintains traffic flow in critical areas.
Enhanced user safety
Many users also ask whether automatic doors include emergency opening functions. NABCO automatic door solutions are specifically designed to facilitate safe passage and emergency egress. The combination of manual operation capability, mechanical locking systems, and optional backup power solutions significantly reduces the risk of users becoming trapped during a power failure.
Is a UPS necessary for automatic doors?
Although the answer to Can automatic doors be opened during a power outage? is clearly yes, installing a UPS is still highly recommended for facilities with heavy usage or continuous operational requirements.
A UPS provides several benefits:
- Maintains door operation during power outages.
- Reduces operational disruptions.
- Improves user experience.
- Supports traffic flow in critical areas.
For hospitals, airports, hotels, and shopping malls, a UPS should be considered as part of the system design from the beginning.
Important considerations for safe operation during power outages
Many people only begin asking what to do when an automatic door loses power after an incident has already occurred. However, ensuring uninterrupted access and maintaining safety functions requires regular inspection and maintenance.
A door’s performance during a power outage depends not only on its original design but also on the condition of components such as:
- Manual opening mechanisms and mechanical locks.
- UPS units and backup batteries.
- Safety sensors and related safety devices.
- Motors and control systems.
- Emergency procedures for facility operators.
In addition, choosing a qualified maintenance provider plays a crucial role in maintaining system reliability and extending service life. Preventive maintenance not only improves durability but also ensures that safety features function correctly when needed.
