Abstract: 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.

Abstract: An example screening system includes a plurality of detectors about a screening area. Each detector includes a sensor configured to detect information from one or more objects moving along a path from an entrance to an exit of the screening area. The plurality of detectors include a first detector configured to detect information from a first location of the path, and a second detector configured to detect information from a second location of the path. The second detector is configured to adapt its functionality based on a finding of the first detector for a given one of the one or more objects.

Abstract: A method for monitoring an area includes distributing, by a detector unit, light during a first instance of time in order to characterize the area based on first data associated with the first instance of time; distributing, by the detector unit, light during at least a second instance of time in order to obtain second data; comparing a first portion of the second data to at least one of: a second portion of the second data and the first data; and based on the comparison, signaling an alarm condition by the detector unit when an evolution in the second data is detected in an amount greater than a threshold.

Abstract: A flame detector includes a UV sensor sensitive to solar UV radiation and a secondary sensor sensitive to non-UV radiation. A controller is operatively connected to the UV sensor and the secondary sensor to: signal an alarm in response to receiving input from the UV sensor indicative of a strong UV source and input from the secondary sensor indicative of a weak non-UV radiation source; and suppress an alarm in response to receiving a signal from the UV sensor indicative of a strong UV source and a signal from the secondary sensor indicative of a strong non-UV radiation source.
