Abstract: A lock latch mechanism disposed within a powered locking device of a transit vehicle door system for maintaining a lock lever in an unlock position without the aid of the lock actuator. The lock latch mechanism includes a lock latch lever biased for engagement with an unlock cam through the use of a bias spring. The lock latch mechanism further includes a reset lever assembly engaging such lock latch lever during the door closing motion to allow movement of the lock lever form such unlocking position into such locking position to maintain at least one door of the transit vehicle in the fully closed and lock position. A manual release lever is provided to move the lock lever from such locking position into such unlocking position enabling the lock latch mechanism to maintain the lock lever in such unlocked position.

Abstract: A surface-mounted door holder-closer responsive to the products of combustion passing through multiple passageways formed in a holder-closer housing cover, a holder-closer assembly frame, and a static shield which is an integral part of an ionization chamber module. The ionization chamber module is insertable into the holder-closer frame with the frame and static shield not only defining the passageways, but also isolating the ion chamber from spurious static charges generated within the housing which would render a false alarm or false emergency door release. The frame also houses the principal components of the holder-closer, namely, a closer spring, a dashpot, a latching lever assembly, and an electromagnet responsive to modulated current flow in the ionization chamber to effect alarm or emergency release of the latching lever to close an otherwise open door. The integrated detector-holder-closer is advantageously and simply mounted on the lintel or header of a door frame.
