摘要： A method of operating a detection system includes switching the system from a normal mode for sensing smoke to a high sensitivity mode for sensing airborne particles, such that in the high sensitivity mode the detection system is configured to discriminate between particles of diameters less than 2.5 micrometers and 10 micrometers. Transmitting light from one or more light sources of the detection system into a monitored space, and detecting scattered light at one or more light sensing devices of the detection system. The detection of scattered light is indicative of one or more indoor air quality conditions in the monitored space.

摘要： A particle detector. The particle detector comprises one or more light sources, an optical sensor, and a controller. The one or more light sources are collectively operable to simultaneously produce at least two wavelength ranges of emitted light. The optical sensor is configured to sense light of the at least two wavelength ranges emitted by the one or more light sources and to distinguish each range. The controller is configured to detect particles based on the light sensed by the optical sensor.

摘要： To provide a detector capable of reliably inducing a gas containing a detection target to a detection space. A detector which is attached to an installation surface of an installation target and has an attachment surface facing the installation surface includes a detection space into which a detection target flows; a light-emitting portion and a light-receiving portion which detect the detection target flowing into the detection space; a casing which accommodates the light-emitting portion, the light-receiving portion and the detection space; and a rib, an inclined surface, a light shielding portion, a casing side inflow opening, a substrate side outflow opening, a casing side outflow opening, a back plate, and the like which induce gas outside the casing, which is gas containing the detection target, to flow into the detection space inside the casing from an opposite side of the attachment surface of the casing and to flow out from the side of the attachment surface of the casing in a direction substantially orthogonal to the attachment surface.

摘要： A detection system for measuring one or more conditions within a predetermined area includes a fiber optic cable including a first core for transmitting light to the ambient atmosphere adjacent a node and a second core for receiving scattered light from the ambient atmosphere adjacent the node. A discrimination assembly operably coupled to the first and second cores includes at least one focusing element and at least one optical enhancement device. The at least one optical enhancement device separates the scattered light received from the ambient atmosphere into a plurality of wavelengths. A control system operably coupled to the fiber optic cable receives the scattered light received from the ambient atmosphere. The scattered light received from the ambient atmosphere has a higher frequency than the light transmitted to the ambient atmosphere and only the scattered light having a desired wavelength is transmitted to the control system.

摘要： Embers created by fires, particularly fires in environments such as grassland, bushland, and forests, can lead to the loss of property and animal and human lives. In addition to the loss of property and lives, fires caused by embers lead to an increase in greenhouse gasses, an increase in the risk associated with an ember attack and/or a fire, and a reduced ability to effectively fight an ember attack and/or a fire. The concept bush/wildfire should be understood to include forest fires, grassland fires, and the like. The present disclosure relates to an ember detector device, a bush/wild fire detection and threat management system, and methods of reducing greenhouse gasses, reducing the risk associated with an ember attack and/or a fire, and enhancing an ability to effectively fight an ember attack and/or a fire.
