Frequently Asked Questions

Q: Is this electric rim lock compatible with my video intercom or door phone system?

A: Yes. This 12V DC electric rim lock is designed to work with standard video intercom systems and access control systems using a simple 2-wire connection. Most residential and commercial intercom door phone systems that support an electric strike or rim lock output at 12V DC are compatible.

Q: What happens if the power goes out — will my door stay locked?

A: Absolutely. This lock operates in Fail-Secure (NO Mode), meaning the bolt remains extended and the door stays locked whenever power is disconnected. This is ideal for exterior doors where security must be maintained regardless of power status. The door can still be opened manually with a key from either side during a power outage.

Q: How do I know whether to choose the left-opening or right-opening version?

A: Stand facing the door from the outside. If the hinges are on your left, you need a left-opening lock; if the hinges are on your right, choose the right-opening version. Selecting the correct orientation is essential for proper bolt alignment and operation.

Q: What door thicknesses does this electric rim lock support?

A: This lock is compatible with doors between 35mm (approximately 1-3/8 inches) and 55mm (approximately 2 inches) thick. It is suitable for both wood and iron door types.

Q: Can the outside button be disabled for added security?

A: Yes. When you lock the door from the inside using your key, the exterior button on the lock body is automatically disabled. This Safe Lock Mode prevents anyone outside from triggering the electric release, giving you an extra layer of security when needed.
