摘要： A detection system including a smoke detector configured to transmit a detector baseline signal to at least one of a control panel and a server (e.g., to establish at least one indoor air quality trend), and a method for monitoring indoor air quality with at least one smoke detector are provided. The smoke detector includes a processor configured determine whether a current condition indicates a need to trigger an alarm. The smoke detector is configured to measure a baseline. The detector baseline signal is used (e.g., by the control panel and/or the server) to establish at least one indoor air quality (IAQ) trend.

摘要： A smoke detector is provided and includes a housing defining a chamber for receiving ambient materials, a single receiver, first and second emitters configured to emit light into the chamber to be respectively scattered from the ambient materials toward the single receiver with back scatter and forward scatter effects, respectively, and a controller. The single receiver generates first and second output signals in accordance with the light respectively scattered toward the single receiver with the back and forward scatter effects, respectively. The controller is receptive of the first and second output signals and determines whether a condition is appropriate to trigger an alarm.

摘要： A smoke alarm includes a housing having a generally hollow interior, a printed circuit board arranged within the interior of the housing, and an optical chamber assembly connected to the printed circuit board. The optical chamber assembly has an interior chamber and at least one smoke entry location. A substantial entirety of the interior chamber is external to the housing. At least one light device for evaluating particles is arranged within an interior chamber of the optical chamber assembly.
