A discharge assembly is mounted to the first port and has a discharge valve (50, 52) and a first monitoring switch or sensor (230 240) having a normally closed output (532) and a normally open output (534). A first monitoring system (100) is coupled to one of the normally closed output and the normally open output. A second monitoring system (340) is coupled to the other of the normally closed output and the normally open output.

Abstract: An integrated communication and smoke detection system 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 one or more conditions at a predetermined area. A light source is operably connected to the fiber harness to transmit light along the at least one fiber optic cable to the node. A control system 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. The control system is configured to allow multiple inputs and outputs for communication of information through the fiber harness and node using modulated light.

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 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.

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.
