I have three doctor offices the I need to install a ceiling mounted light in each office with three switches at the receptionist office so the receptionist can notify the doctors that there is a patient waiting for them. It's all on one floor with a suspended ceiling and the offices are about 60 feet away from where I would place the switches. I do not know why they can't just page him on the phone but who am I to argue with a bunch of doctors. They want to keep the cost down too so I have been scanning the internet trying to fine a low voltage signal lights and switches . I'm hoping somebody on this board has some ideas.
