Frequently Asked Questions
Q: What does "fail-safe" mean for this electric bolt lock?
A: A fail-safe electric bolt lock means the bolt engages (locks) when power is applied and automatically retracts (unlocks) when power is cut. This ensures doors can be safely exited during a power outage or emergency, making it a common choice for access control in commercial and residential buildings.
Q: Is this electric bolt lock compatible with standard access control systems?
A: Yes. This DC 12V 2-wire bolt lock is designed to integrate easily with most standard access control panels, keypads, card readers, and intercoms that support a 12V DC output. The simple two-wire connection makes setup quick and compatible with a wide range of systems.
Q: Can this lock be used on a frameless glass door?
A: Absolutely. This electric bolt lock is especially well-suited for 180° swing frameless glass doors, in addition to wood and metal door frames, making it a versatile choice for modern office and commercial environments.
