Abstract: A smoke detector operational integrity verification system includes a plurality of electronic components. Also included is a controller in operative communication with the plurality of electronic components. Further included is an evaluation module of the controller receiving an output signal of the plurality of electronic components as an output voltage over a period of time, the output voltage measured at a plurality of times compared to predefined acceptable ranges.

Abstract: A fire detector mounting assembly includes a housing having a first electrical connector device disposed on an engagement side of the housing. The assembly also includes a socket operatively coupleable to the housing, the socket having a second electrical connector device axially engageable with the first electrical connector device to electrically connect the housing and the socket. The assembly further includes a housing collar located at a radially outer location of the housing, the housing collar independently rotatable relative to the rest of the housing.

Abstract: A smoke detector dynamic range adjustment system includes a light emitting element for emitting light at a plurality of light output levels, the plurality of light output levels automatically adjusted by a controller when a saturation limit is approached. The system also includes a light receiving element for receiving light emitted from the light emitting element.

Abstract: An automatic cover detection system for a fire detector is provided. The system includes a fire detector top cover having an exposed surface. The system also includes a sensor assembly operatively coupled to the fire detector to detect the presence of an object in contact with or in close proximity of the fire detector top cover and at least partially covering the exposed surface of the fire detector top cover.
