Frequently Asked Questions
Q: What is the difference between Fail Secure (NO) and Fail Safe (NC) on this electric strike lock?
A: In Fail Secure (NO) mode, the lock remains locked when power is cut — you must apply 12V DC to release (open) the door. This is best for secure areas like server rooms or offices. In Fail Safe (NC) mode, the lock remains unlocked when power is cut — power is applied to keep the door locked. This is often required for fire exits and emergency egress doors to ensure free passage during a power outage.
Q: What types of doors is this electric strike lock compatible with?
A: This 12V electric strike lock is designed for a wide range of door types, including glass doors (framed), aluminum frame doors, stainless steel doors, and standard wooden or metal frame doors. Its embedded installation design gives a clean, professional finish on most door frames.
Q: What access control devices can I use with this electric strike lock?
A: This lock is compatible with virtually any standard 12V DC access control system, including keypad entry systems, RFID card readers, biometric scanners, video intercoms, and push-button exit systems. Simply wire the lock output of your access control panel to the lock's terminals.
Q: Is professional installation required for this electric strike door lock?
A: While the lock can be installed by a confident DIYer familiar with basic wiring, professional installation by a licensed locksmith or security technician is recommended — especially for commercial applications — to ensure correct wiring, compliance with local building codes, and optimal performance.
Q: What holding force does this electric strike lock provide?
A: This electric strike lock delivers an impressive 800 kg (approximately 1,760 lb) of holding force, making it suitable for securing doors in both residential and light commercial environments where robust access control is needed.
