摘要： A pneumatically controlled exit device assembly for remote latching and unlatching of a door by controlling air pressure directed to the exit device from a pneumatic pressure source is described. The device includes a push bar operated exit device for retracting a latch of the emergency door, with the exit device having an air cylinder assembly biased to control retraction of the latch in response to changes in applied air pressure. In addition, a pneumatic transfer assembly is provided in fluid connection between the pneumatic pressure source and the air cylinder assembly, with the pneumatic transfer assembly having an air line and a mechanism for protecting the airline positioned between the door frame and the door.
