Abstract: Non-coaxial systems, methods, and devices for detecting smoke are described herein. A smoke detection system may comprise a laser emitter configured to emit a laser beam, and a light receiver. The light receiver may comprise a first receiver lens, wherein a field of view of the first receiver lens includes at least a portion of the laser beam. The light receiver may also comprise a second receiver lens, wherein a field of view of the second receiver lens includes at least a portion of the laser beam and a region between an edge of the field of view of the first receiver lens and the laser emitter.

Abstract: Apparatuses, methods, and computer-readable media for operating a scanning smoke detector are described herein. One apparatus a laser emitter configured to emit a beam of light, a rotational component configured to rotate the emitter such that the beam periodically scans across an area, and a light receiver configured to receive a reflected portion of the beam of light and determine a presence of smoke particles in the area based on the reflected portion. The smoke detection apparatus can be configured to operate at a first power level, decrease the beam to a second power level responsive to a determination that an object in the area is in a path of the beam, and increase the beam to the first power level responsive to a determination that the object is no longer in the path of the beam.

Abstract: A smoke detector, and methods of operating a smoke detector, are described herein. In some examples, one or more embodiments include a laser emitter configured to emit a laser beam that illuminates an object in an area, a light receiver configured to receive light reflected from the illuminated object, and a controller configured to determine, based on the light reflected from the illuminated object, an amount of space in the area that is blocked from a field of view of the smoke detector by the object, and provide an indication responsive to the determined amount of space being above a threshold amount of space.

Abstract: Systems, methods, and devices of providing a sensing system for fire event detection in a space within a facility are described herein. One method, includes activating a physical sensor of a physical alarm system detector device to monitor a space of a facility for a fire event to occur, defining a virtual voxel structure mapped in at least three dimensions to a virtual monitored space created to represent the space of the facility being monitored, and locating a virtual object within the virtual voxel structure by mapping a virtual object location based on sensing a location of a physical object with the physical sensor within the space.
