The company I work for installed this doors that used this on a low roof of a sky scraper. To keep people from accessing the low roof, I was instructed to install the thumb turn to the outside and the key cylinder to the inside. The goal was to use the key on the inside and lock the door. But when someone turns the handle inside I unlocks both the latch and deadbolt. I'm thinking it has to do with the deadbolt mechanism inside the door. We can't just change the thumb turn to the outside and expect it to work. I don't know if this made sense to anyone. But if anyone can help. I'd appreciate it very much.
