Crafted from high-quality zinc alloy and finished with a high-temperature resistant paint, this button offers exceptional durability and a professional appearance suitable for both commercial and residential door release applications.

Advantages

This exit button stands out due to its robust construction, which ensures long-term reliability even in high-traffic environments. The zinc alloy housing provides excellent resistance to physical wear, while the specialized paint finish protects the unit from environmental factors. With a mechanical service life of approximately 500,000 operations, it is designed to provide consistent performance over many years of daily use.

Suitable for

• Commercial office building access control
• Residential apartment building main entrances
• Automated gate systems
• Emergency exit door release mechanisms
• Industrial facility security points

This device may not be suitable for outdoor environments exposed to direct rain or extreme weather conditions, as it is designed for general access control rather than harsh exterior exposure. It is also not intended for use in high-voltage electrical circuits, as it is strictly a low-voltage signaling component.

Installation involves surface mounting the button near the exit point. Ensure the wiring is connected to the NO and COM terminals according to your access control panel requirements. The compact dimensions allow for installation on door frames or walls where space is limited. Once mounted, the button provides a simple mechanical trigger to release the electronic lock.

What to consider before purchase

• Verify that your access control system supports NO/COM contact configurations.
• Ensure the mounting surface is flat and stable for secure installation.
• Check the operating temperature range to ensure it matches your installation environment.

For optimal performance and longevity, ensure that the wiring connections are properly insulated and protected from moisture. Regular inspection of the button surface and mechanical movement is recommended to maintain smooth operation.
