Stopping the rated door from closing is/was my biggest concern....Cycled them a bunch of times with the FM and it didn't come close to being an issue....More interested if this violates a listing on the hold open or something in NFPA 80 and haven't had time to rip into thatNow that i think about it, i can see 2 problems on release: smack somebody in the head, and/or the plate swings around and get in front of the door, and prevents it from closing all the way.
