As most of you know, a required egress door must typically operate with only one motion to release the latch. The common exception is dwelling unit entry doors in hotels and apartment buildings, which can have one additional locking device if the occupant load of the unit is 10 or less. Take a look at this door, sent to me by Jeff Strangio of Maffey’s Security Group. Do you think you could figure out how to open it in smoky conditions?
