The added mechanical shear force between the door and frame increases overall resistance to lateral stress. When access is granted — or power is cut — the lock releases instantly. The 0\/3\/6\/9-second adjustable delay allows the door to close fully before the lock engages, preventing misalignment and improving reliability in daily use.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Maintenance Tips\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProfessional installation is recommended to ensure precise alignment between the lock body and iron strike plate.\u003c\/li\u003e\n  \u003cli\u003eMaintain a gap of \u003cstrong\u003e3–4 mm\u003c\/strong\u003e (minimum 2 mm) between the lock body and iron plate.

The FBD-1200LS supports both \u003cstrong\u003eDC 12V and DC 24V\u003c\/strong\u003e power inputs, making it compatible with most standard access control power supplies. Simply verify your system's voltage before wiring.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the time delay function do?\u003c\/h4\u003e\n\u003cp\u003eA: The adjustable time delay (0, 3, 6, or 9 seconds) controls how long the lock waits after the door closes before engaging. This ensures the door is fully shut and properly aligned before the electromagnetic force activates, reducing wear and improving locking reliability.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this lock fail-safe or fail-secure?\u003c\/h4\u003e\n\u003cp\u003eA: This shear lock is \u003cstrong\u003efail-secure (power-to-lock)\u003c\/strong\u003e — the door is locked when power is ON and unlocks when power is cut. For emergency scenarios such as fire alarms, it is designed to integrate with fire alarm systems to automatically release, allowing safe egress.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this lock require professional installation?\u003c\/h4\u003e\n\u003cp\u003eA: Professional installation is strongly recommended. Proper alignment of the lock body and iron strike plate is critical to performance.
