Frequently Asked Questions
Q: Is this solenoid door lock fail-secure or fail-safe?
A: This electric door lock catch is fail-secure. When power is OFF, the internal spring keeps the latch tongue extended, keeping the door locked. Power must be applied to retract the tongue and unlock the door. This is ideal for security-sensitive applications where you want doors to remain locked during a power outage.
Q: What power supply does this solenoid lock require?
A: The lock requires a DC 12V power supply at 0.4A. It is compatible with standard 12V DC access control power supplies. Make sure your power source matches these specifications for reliable, safe operation.
Q: Can this electric door lock catch work with my existing access control system?
A: Yes — the Asia-Teco LKmini08 is designed to integrate with most standard access control panels, keypads, card readers, remote controllers, and intercom systems that output a DC 12V switched signal. Simply wire the red and green leads to your controller's lock output terminals.
Q: How difficult is the installation?
A: Installation is straightforward. The unit uses a simple 2-wire connection (red to positive, green to negative) and mounts to your door frame. Basic DIY skills and standard tools are sufficient. Always ensure power is off before making electrical connections and follow local electrical codes.
