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 smoke detector and method for testing a smoke detector are provided. The smoke detector includes a housing defining a chamber, an emitter, and a receiver. The housing includes an inlet port and an outlet port configured to allow an airflow to pass through the chamber. The emitter is configured to emit light into the chamber. The receiver is configured to receive light reflected by ambient materials in the airflow passing through the chamber. The smoke detector includes an entry point and an exit point, defining a channel therebetween. At least a portion of the airflow passes through the channel. The channel is in fluid communication with a sensor. The sensor is configured to detect at least one of a pressure differential and a mass flow of the airflow. The smoke detector and method for testing the smoke detector enable in situ testing of the smoke detector.
