Abstract: A system for measuring a status of a detection device having a component transformable between a plurality of configurations includes a fiber optic cable for transmitting light. The at least one fiber optic cable defines a node arranged in communication with the component. A control system is operably coupled to the fiber optic cable such that scattered light reflected from the component and returned to the node is transmitted to the control system. The control system analyzes the scattered light to determine the configuration of the component.

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: A detection system for measuring one or more conditions within a predetermined area includes at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining a plurality of nodes arranged to measure the one or more conditions. A control system is in communication with the at least one fiber optic cable such that scattered light and a time of flight record is transmitted from the at least one fiber optic cable to the control system. The control system includes a detection algorithm operable to identify a portion of the scattered light associated with each of the plurality of nodes and indicate a presence and magnitude of the one or more conditions at each of the plurality of nodes.

Abstract: A detection system for measuring one or more conditions within a predetermined area includes a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining a node arranged to measure the one or more conditions. A control system is operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node. An optical enhancement device is operably connected to the fiber harness or to the control system to reduce interference sources transmitted from the node.

Abstract: An integrated detection and suppression system includes a fiber harness having at least one fiber optic cable for transmitting light defining at least one node arranged to measure one or more conditions. A light source is operably connected to the fiber harness to transmit light along the fiber harness to the at least one node. A control system is operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the scattered light to determine at least one of a presence and magnitude of the one or more conditions. At least one suppressant outlet is associated with at least one node and is operably connected to the control system configured to initiate a response for the delivery of a volume of suppressant through a suppressant outlet associated with a particular node.

The at least one fiber optic cable defines a node arranged to measure the one or more conditions. A control system is operably coupled to the fiber harness such that a signal indicative of scattered light associated with the node is transmitted to the control system. The control system analyzes the signal associated with the node in one or more of a frequency domain, time-frequency domain, time domain, and spatial domain, to determine at least one of a presence and magnitude of the condition within the predetermined area.

Abstract: A photoacoustic detection system (20) includes a detector (22) that has a chamber (24), a pulsed light source (26), piezoelectric tuning forks (28), and a photosensor (30). 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 (38) 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.
