A set of access control was installed at the door of a company office the day before yesterday, the FC-500 electric bolt lock was used, the lock was installed on the ground and facing upward. I used it normally after the initial installation, but why did the round lock bolt not pop out after a few days? Is it back to normal after being removed?

When the FCL-500 series electric bolt lock is also called "down bolt lock" . When designing, the bolt (the iron rod pushed out) is facing downward, and you install the lock on the ground instead of installing it according to the standard. However, all electrical plugs cannot be installed in your way, installing on the ground with the lock tongue facing upwards will cause sand and dust to fall into the lock hole and jam the lock bolt to pop out and fail to work. It is recommended to reinstall the lock and install it according to the instructions.
