Smoke damper
A multi-point latching system for a smoke damper system comprising a motorised opening and closing mechanism 16 for a smoke damper door in a frame, and a multi-point latching mechanism 48 mechanically connected to the motorised opening and closing mechanism such that as the motorised opening and closing mechanism unlatches the multi-point latching mechanism before then opening the smoke damper, and closes the smoke damper before then latching the multi-point latching mechanism. There may be an upper and lower latch 26 with a spring trigger mechanism to trigger the latches when the door is closed. The multi-point latching system has two rods 46 that get pulled in to latch top and bottom latches and also operate a central latch. There may be a transfer box (fig 12) with a plate and two sets of non-parallel slots in each of which an actuator member runs such that movement of the plate in and out of the housing causes the rods to move in a perpendicular direction. The actuator members also cause two catch plates (52 54 Fig 18/19) to move towards or away from each other to latch the system.
