I put in alot of Savaria Orions. They are good solid units IF a top notch install is done with attention to detail on every step and you almost have to install a few to learn the hard way what things you need to do differently to have them running flawless. Still a chinsy arse valve, not the best ride, even with new dedicated plc to run the valve.
Cemco was the bees knees. But they went the way of the dodo bird.
Ive installed one Symmetry LULA and maintain one on my route now. I'm impressed. Yes symmetry has a proprietary plc tool to setup the plc, but they are, in my opinion, the top residential elevators and LULAs on the market. Good solid well thought out designs. No BS, uses a blain valve. GAL operator and door equipment.
