Yotogi YS17NO12D Electric Strike, NO, 12V DC, Fail-Safe, Symmetrical, Built-in Diode

The Yotogi YS17NO12D is a high-quality symmetrical electric strike engineered for integration into modern access control systems. Operating on a 12V DC power supply, this fail-safe device is designed to remain in an unlocked state when powered, ensuring safety and accessibility in various environments. The inclusion of a built-in diode provides essential protection for your control electronics by suppressing voltage spikes during operation, which significantly extends the lifespan of the connected hardware.

Advantages

This electric strike offers a robust and reliable solution for door locking mechanisms. Its symmetrical design allows for versatile installation on both left and right-handed doors, simplifying the mounting process for installers. The fail-safe configuration is particularly beneficial for fire safety and emergency exit requirements, as the door automatically unlocks upon power loss. Furthermore, the compact dimensions ensure compatibility with a wide range of door frames, while the integrated diode eliminates the need for external surge protection components, resulting in a cleaner and more efficient installation.

Suitable for

• Office building access control systems
• Emergency exit doors requiring fail-safe operation
• Residential apartment building entrance doors
• Integration with intercom and video door phone systems

When it may not be suitable

This device is not suitable for applications requiring high-security locking where the door must remain locked during a power failure, as this is a fail-safe model. It is also not intended for outdoor environments exposed to direct weather conditions without appropriate protective housing.

Key specifications

• Operating voltage: 12V DC
• Configuration: Fail-safe (Normally Open)
• Design: Symmetrical
• Protection: Integrated diode
• Compatibility: Standard door frames

How to use

Installation should be performed by a qualified technician to ensure proper alignment with the door latch. The strike is mounted into the door frame, replacing the standard strike plate. Ensure that the 12V DC power supply is correctly wired to the terminals, observing the polarity if required. Once installed, test the strike by applying power to verify that the locking mechanism releases as intended. Regular maintenance involves checking the alignment and ensuring the strike plate remains free of debris for smooth operation.

What to consider before purchase

• Verify that your access control system supports fail-safe (normally open) operation.
• Ensure your power supply provides a stable 12V DC output.
• Check the dimensions of your existing door frame to confirm compatibility with the strike size.
• Confirm if your local building codes require fail-safe or fail-secure hardware for your specific door type.

Usage recommendations

For optimal performance and longevity, ensure the electric strike is installed in a dry, indoor environment and that the door is properly adjusted to prevent excessive pressure on the latch mechanism.
