Frequently Asked Questions

Q: How do I pair the 315MHz remote handle exit buttons to the controller?

A: The LIHTNE DR-2 controller uses a learning-type encoding system. Simply press the programming/learn button on the controller, then press the button on your remote handle exit button. The controller will memorize the signal, and the pair will be ready to use within seconds. Repeat for the second remote handle.

Q: What is the difference between Fail-Safe and Fail-Secure modes on this electric bolt lock?

A: In Fail-Safe mode, the lock unlocks automatically when power is lost — ideal for emergency egress applications. In Fail-Secure mode, the lock remains locked when power is cut, keeping the secured area protected even during a power outage. The LIHTNE DR-2 controller supports both modes, so you can configure it to match your specific security needs.

Q: What voltage and power supply does this mini electric bolt lock require?

A: Both the controller and the mini electric bolt lock operate on DC 12V. A compatible power supply adapter is included in the package, so no additional power supply is needed for standard installations.

Q: Can I adjust the unlock delay on the DR-2 controller?

A: Yes. The delay time is fully adjustable from 0 to 60 seconds, allowing you to customize how long the bolt remains unlocked after a remote signal is received — giving you precise control over access timing for your application.
