In \u003cstrong\u003eFail Secure (NO)\u003c\/strong\u003e mode, the lock releases (unlocks) when powered and engages (locks) when power is removed — best suited for high-security areas where the door must remain locked during a power outage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What door types is this electric drop bolt lock compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The Asia-Teco B7L drop bolt lock is compatible with most standard door types, including glass doors, wooden doors, metal doors, and reinforced security doors, making it highly versatile for residential, commercial, and industrial applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the time delay function work on the B7L electric mortise lock?\u003c\/h4\u003e\n\u003cp\u003eA: The lock features a user-selectable time delay of 0, 3, or 6 seconds. This delay controls how long after receiving the unlock signal the bolt retracts, giving occupants time to react and pass through the door before the bolt re-engages — a useful feature in high-traffic access points.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the signal feedback feature do?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in signal feedback output allows your connected access control panel, alarm system, or building management system to monitor the real-time status of the lock (locked or unlocked), enabling better automation, logging, and security oversight.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply is required for this electric drop bolt lock?\u003c\/h4\u003e\n\u003cp\u003eA: The lock operates on DC 12V. The starting current is 1.1A and the working (holding) current drops to 0.14A, making it energy-efficient for continuous operation.
