Details of the problem:
Hello, I chose your FC-198E access controller, we are usually busy in the office, visitors press the doorbell button on the FC-198E access controller, but the doorbell does not move at all, how can I solve it?
Expert answer:
Hello, our FC-198E access controller supports the doorbell function, but the doorbell must be connected externally. The FC-198E access controller itself only carries the doorbell button instead of the doorbell, it is recommended that you purchase the doorbell together when purchasing the device to achieve the doorbell function!
