    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.
