Frequently Asked Questions
Q: What is the difference between the Fail Safe (NC) and Fail Secure (NO) modes on this electronic mortise lock?
A: In Fail Safe (NC) mode, the lock remains open (unlocked) when power is cut — ideal for emergency egress applications where doors must be freely accessible during a power outage. In Fail Secure (NO) mode, the lock remains locked when power is cut — best for high-security areas where you want doors to stay locked even during a power failure. You can choose the model that best suits your security needs.
Q: What types of doors is this DC12V electronic mortise lock compatible with?
A: This mortise latch bolt lock is suitable for a wide range of door types, including glass doors, wooden doors, metal doors, and reinforced security doors. Its compact 200 × 38 × 28 mm aluminum alloy body fits standard mortise cutouts and integrates easily with most access control systems running on DC 12V.
Q: How does the detection signal feedback work on this latch bolt lock?
A: The built-in detection signal feedback provides a real-time status signal to your access control panel or monitoring system, indicating whether the door is currently locked or unlocked. This allows for remote monitoring, audit logging, and integration with alarm systems — adding an extra layer of oversight to your security setup.
Q: Can I adjust the time delay on this electronic mortise lock?
A: Yes. The lock offers three selectable time delay settings — 0 seconds (instant), 3 seconds, or 6 seconds — allowing you to fine-tune how long the lock stays in the unlocked state after receiving an access signal. This is useful for managing pedestrian flow in busy entry points.
