Good day. I would like to connect the bell switch to the Metro 800 drive of the Wiśniowski gate in order to be able to open and close without a remote control. Unfortunately, there is no information in the manual and diagrams where you can install such a switch. The only thing I found was the possibility of connecting a key switch or a code keyboard. There is no mention of bell-type switches. Has anyone installed something similar to the Wiśniowski gates and can suggest how to connect it?
