Frequently Asked Questions

Q: What does "fail secure" mean on the Asia-Teco B9L electric drop bolt lock?

A: "Fail secure" (also called Normally Open or NO) means the lock remains in the locked position when power is cut. This is the opposite of "fail safe" locks, which unlock when power is lost. A fail secure lock is ideal for high-security doors where you need to ensure the door stays locked during a power outage.

Q: Can I use the B9L drop bolt lock without an access control panel?

A: Yes. The lock includes manual keys for direct override, allowing you to lock or unlock the door without any power or access control system. This makes it versatile for both standalone use and integration into a larger access control setup.

Q: How do I set the time delay on the electric deadbolt?

A: The B9L features an adjustable time delay of 0, 3, or 6 seconds. This can be configured to control how long the bolt remains retracted (unlocked) after an access signal is received, giving users adequate time to pass through the door before it re-locks automatically.

Q: Is the Asia-Teco B9L compatible with standard 12V access control systems?

A: Yes. The lock operates on DC 12V and features a 6-wire output for door status monitoring, making it compatible with the vast majority of commercial and residential access control panels, intercoms, and keypads on the market.
