Fail Safe vs. Fail Secure — What's the Difference?
Fail Safe (NO): The lock releases (door unlocks) when power is cut — ideal for emergency egress applications where doors must remain passable during a power outage.
Fail Secure (NC): The lock stays engaged (door remains locked) when power is cut — preferred for high-security areas where access must remain restricted even during outages.
With the LIHTNE 124KS, switching between these modes takes only seconds via a screw-position adjustment, giving installers maximum flexibility on the job.

Frequently Asked Questions
Q: What is the difference between the 2-cable and 4-cable versions of the LIHTNE 124KS electric strike lock?
A: The 2-cable version provides standard power connections without signal feedback. The 4-cable version adds a signal feedback wire, allowing your access control system to monitor the lock's status (open/closed) in real time. Choose the 4-cable version if your controller supports status monitoring.
Q: How do I switch between Fail Safe (NO) and Fail Secure (NC) mode?
A: Switching modes is straightforward — simply reposition the adjustment screw on the unit. No rewiring or additional tools are required. This makes the LIHTNE 124KS highly versatile for different installation requirements.
Q: Is this electric strike compatible with standard access control power supplies?
A: Yes. The lock operates at 12V DC and draws only 250mA, making it compatible with the vast majority of access control power supplies and controllers available on the market today.
Q: What door types is the ANSI electric strike designed for?
A: ANSI electric strikes are designed to fit standard ANSI-format door frame cutouts, commonly found on aluminum, hollow metal, and wood frame doors used in commercial and residential settings. Always verify your door frame dimensions before purchasing.
