Abstract: A method of calibrating an optical detector includes installing a calibration system within at least one sensing volume of the optical detector, filling a chamber of the calibration system with a material to achieve a known obscuration, and measuring an obscuration of the material within the chamber.

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 SPR detection system includes a first prism having a first surface adjacent to a first metal layer exposed to a sample gas, and a second prism having a second surface adjacent to a second metal layer exposed to a reference gas. At least one light source is configured to provide respective beams to the first and second surfaces, where each of the beams causes SPR of a respective one of the metal layers. At least one photodetector is configured to measure a reflection property of reflections of the respective beams from the metal layers during the SPR. A controller is configured to determine whether a target gas is present in the sample gas based on a known composition of the reference gas and at least one of an electrical property of the first and second metal layers during the SPR and the reflection property of the metal layers.

Abstract: A detector assembly for a duct of a heating ventilation and air conditioning system includes an outer housing having at least one through hole formed therein, an inner sampling support receivable within a hollow interior of the outer housing, and at least one detector mounted to the inner sampling support. The at least one detector is axially aligned with the at least one through hole when the inner sampling support is installed within the hollow interior of the outer housing. The at least one detector is operable to sample air within the duct to detect a hazardous condition.

Abstract: A photoacoustic detection system includes a detector that has a chamber, a pulsed light source, piezoelectric tuning forks, and a photosensor. The chamber has an inlet and an outlet for flow of an analyte. The pulsed light source is adjacent the chamber and is operable to emit a light beam along a path through the chamber. The tuning forks are arranged along the path, and each of the tuning forks is operable to emit first sensor signals. The photosensor is arranged along the path and is operable to emit second sensor signals. A controller is connected to receive the first and second sensor signals. The controller is configured to determine whether a target species is present in the analyte based on the first sensor signals and determine whether the target species is present in the analyte based on the second sensor signals.

Abstract: A detection system includes a host detection system that has at least one primary hazard detector and a controller connected for communication with the at least one primary hazard detector. At least one portable auxiliary hazard detector can be temporarily introduced in a vicinity of the host detection system and link with the controller of the host detection system to provide additional detection capability. The portable auxiliary hazard detector has at least one light source that can emit a light beam, and at least one photosensor that is operable to emit sensor signals responsive to interaction of the light beam with an analyte.
