Professional Grade Security for Commercial Doors
When it comes to building security, you need hardware you can trust. The YLI YB-100S Electric Bolt Lock is a heavy-duty, concealed locking mechanism designed for modern access control systems. Operating on a standard 12V DC power supply, it integrates seamlessly with RFID keypads, biometric scanners, and intercom systems. Its concealed mortise installation provides a clean, tamper-resistant finish, making it the top choice for corporate offices, retail storefronts, and secure server rooms.
Fail-Safe Operation for Fire Safety Compliance
Safety is just as important as security. The YB-100S operates on a Fail-Safe mechanism (also known as "Power to Lock"). This means the lock requires continuous electrical power to keep the bolt extended. In the event of a building power failure or a triggered fire alarm, the power is cut, and the bolt automatically drops to unlock the door. This ensures personnel can evacuate safely and quickly without being trapped inside.
Ultra-Low Temperature & Durable Design
Traditional electric locks often overheat, leading to coil burnout and premature failure. The YLI YB-100S features an advanced ultra-low temperature design, ensuring the lock body remains cool even under continuous 24/7 operation. The locking bolt itself is machined from solid stainless steel, boasting a 16mm diameter and 16mm protrusion, providing massive holding force against forced entry.
💡 Pro Tip from Our Technicians
"A common mistake when installing electric drop bolts is underestimating the power supply. While the YB-100S only draws 120mA in standby, it requires a 900mA inrush current for a fraction of a second to push the bolt up. Always use a dedicated access control power supply (like a 12V 3A or 5A unit) rather than a cheap CCTV adapter. If you are unsure how to wire the NC (Normally Closed) and COM terminals to your keypad, drop by our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will draw out the exact wiring diagram for your specific door setup."

FAQ Section
FAQ Section
- What is the difference between Fail-Safe and Fail-Secure?A Fail-Safe lock (like this YB-100S) requires power to stay locked. If the power goes out, the door unlocks. This is required for emergency exit doors. A Fail-Secure lock remains locked when power is lost, which is used for high-security rooms where keeping intruders out is more important than easy exit.
- Can I install this electric bolt on a frameless glass door?Yes, but you will need additional mounting hardware. For frameless glass doors, you must purchase compatible U-brackets (such as the BBK-600 or BBK-700 series) to securely mount the lock body and the magnetic strike plate without drilling into the glass.
- Why does the bolt sometimes fail to drop down and lock?This usually happens if the door is misaligned. The YB-100S relies on a magnetic sensor in the strike plate to detect when the door is fully closed before it fires the bolt. Ensure the gap between the lock body and the strike plate is less than 8mm, and that the holes are perfectly aligned.
