Hello Everyone!

I recently installed an air curtain and had planned to use an electromagnetic reed switch. Unfortunately, the door frame (bi-fold doors) has already been installed and is surrounded by glass panels on all sides so if we were to run wires it would be exposed. I am wondering if anyone has experienced a different way to control this unit in a way that would not require wires. Is there a motion sensor that may do the trick? Please let me know what you think, thanks!

The equipment in question is a Berner series ALC08.
