In facilities such as hospitals, shopping malls, hotels, and office buildings, an automatic swing door must not only operate reliably but also ensure safety during emergency situations. This is one of the key reasons why the NABCO GT-8300 emergency evacuation function has become an important consideration for project owners and design consultants when selecting an automatic door solution. Designed for heavy-duty automatic swing door systems, the NABCO GT-8300 delivers not only powerful and reliable performance but also integrates an emergency evacuation mechanism that helps maintain a safe means of egress during emergencies. In this article, Sonha Auto takes a closer look at this feature to explain why the GT-8300 is highly regarded in modern buildings.
What is the NABCO GT-8300 emergency evacuation function?
According to NABCO’s official documentation, the GT-8300 is equipped with an Emergency Evacuation Function, allowing the door leaf to be opened manually in both directions during an emergency.
Simply put, even when the door is operating in automatic mode, users can manually open the door whenever evacuation or emergency access is required. This ensures that the entrance is not entirely dependent on the automatic control system, helping people evacuate more quickly and safely.
For certain inswing door configurations, NABCO also offers the optional Panic Breakout feature. This mechanism allows the door leaf to swing open in the direction of egress when sufficient force is applied, creating a wider clear opening for pedestrians, wheelchairs, hospital beds, and stretchers.

How does the NABCO GT-8300 emergency evacuation function work?
Under normal operating conditions, the GT-8300 functions like a standard automatic swing door. When a sensor detects someone approaching, the control board processes the signal and activates the motor, allowing the door to open and close smoothly according to the programmed settings.
In an emergency, the operating sequence changes as follows:
- Users can apply force to open the door manually.
- The door can be manually opened in both directions, depending on the system configuration.
- For configurations equipped with Panic Breakout, the Panic Latch automatically releases when sufficient force is applied, allowing the door leaf to swing open in the direction of egress.
- Once the emergency has been resolved, the door can be returned to its normal automatic operating mode.
With this mechanism, the door is more than just an automatic entrance. It also becomes an integral part of the building’s overall safety strategy.
Why is the Panic Breakout mechanism important?
During emergencies such as fires, power outages, or building evacuations, the number of people gathering around an exit can increase rapidly. If the door can only open along its normal operating path, the entrance may quickly become a bottleneck.
The Panic Breakout mechanism allows the door leaf to swing open in the direction of egress, creating a significantly wider passage. This is particularly valuable in hospitals, where wheelchairs, hospital beds, and stretchers frequently need to pass through doorways. It also enables emergency responders to gain faster access to the affected area when every second counts.
According to NABCO’s technical documentation, the Panic Latch is designed specifically for inswing door configurations, ensuring reliable emergency egress while maintaining the stability and performance of the door system during everyday operation.

Advantages of the NABCO GT-8300 emergency evacuation function
Enhanced building safety
One of the key advantages of the NABCO GT-8300 emergency evacuation function is its ability to maintain a clear and accessible escape route during emergencies.
The ability to manually open the door in both directions helps reduce congestion around the entrance, allowing occupants to evacuate more quickly and safely.
Ideal for high-traffic facilities
The NABCO GT-8300 automatic swing door is designed for heavy-duty automatic swing door systems, supporting door leaves weighing up to 250 kg each. This makes it an excellent choice for hospitals, airports, hotels, shopping malls, and office buildings, where doors are required to operate continuously under heavy traffic while still providing reliable emergency egress when needed.
Flexible integration with safety systems
In addition to its emergency evacuation capability, the GT-8300 can be integrated with a variety of building systems, including:
- Fire alarm systems
- Access control systems
- Card readers
- Touchless activation switches
- Other activation devices
This enables the door to operate seamlessly as part of the building’s overall smart entrance solution, maximizing the effectiveness of the NABCO GT-8300 emergency evacuation function in real-world applications.
Complies with international safety standards
In addition to its advanced operating features, the NABCO GT-8300 is designed to meet internationally recognized safety standards. According to the manufacturer’s documentation, the system complies with ANSI A156.10 when installed in the recommended configuration and is certified by UL, ULC, and CSFM. These certifications are widely recognized by project owners, architects, and consulting engineers when specifying automatic door systems for commercial and public buildings.
Easy maintenance and servicing
The GT-8300 features a side-load header design that allows technicians to access the operator from the side without removing the entire door assembly. This smart entrance solution simplifies maintenance, minimizes disruption to building operations, and helps reduce long-term operating and maintenance costs.

When should you choose the NABCO GT-8300 automatic swing door?
For projects that require an entrance system combining reliable operation, enhanced safety, and premium aesthetics, the NABCO GT-8300 is an excellent choice. It is particularly suitable for buildings that require:
- A heavy-duty automatic swing door.
- A concealed operator that preserves the building’s architectural appearance.
- Stable operation under high-frequency use.
- Integration with fire alarm and access control systems.
- An emergency evacuation function to enhance occupant safety.
The GT-8300 is especially well suited to hospitals, hotels, shopping malls, and Grade A office buildings, where the entrance system must not only complement the building’s architectural design but also provide reliable emergency egress. Investing in a solution that meets both aesthetic and safety requirements helps improve operational efficiency while providing greater protection for building occupants.
