Abstract: A door frame having a head member defining the top of a door opening with the head member optionally supporting an electrically actuated door holder-closer. A module having a frame shell section and a detector for the particulate products of combustion supported on the interior of the frame shell section with access openings being formed in the shell section to enable particulate products of combustion to pass through the shell to the detector. A socket formed in the head member receives the module so that any particulate products of combustion flowing through the door opening pass through the module access openings to actuate the detector. The detector is electrically connected to the door holder-closer to effect closing of an otherwise open door in response to the detection of the products of combustion. The detector may be either an ionization or photocell type detector.

Abstract: A surface-mounted door holder-closer responsive to the particulate products of combustion passing through multiple passageways formed in a holder-closer housing cover, a holdercloser assembly frame, and a dark chamber which is an integral part of a photocell particle detector module. The particle detector module is insertable into the holder-closer frame with the frame and dark chamber walls not only defining the passageways, but also isolating the chamber from spurious light entering the chamber 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 output current flow from the dark chamber to effect alarm or emergency release of the latching lever to close an otherwise open door. The integrated detector-holdercloser is advantageously and simply mounted on the lintel or header of a door frame.
