PRESSURE SENSING DEAD BOLT

摘要

An apparatus, system and method including a latching device for displaceably retaining a panel relative to a frame (24). The latching device includes at least one bolt (79) which is carried on the latching device and is operative ly associated with the panel to prevent disengagement of the panel. The latchin g device includes at least one pressure responsive device (26) operatively coupled to the bolt to retain the bolt in a desired position and release the bolt when a predetermined pressure differential occurs relative to two, generally opposite, sides of the panel when a pressure decrease (P1, P2) occurs on one side of the panel.
