Abstract: A life safety detector comprising a housing defining a dark photo detection chamber for receiving ambient material, at least one light source configured to emit light into the detection chamber, at least one light sensing device operable to receive light reflected from the ambient materials in the detection chamber; and a processing device coupled to the at least one light sensing device. In a first mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of smoke, and in a second mode of operation, the light received by the at least one light sensing device within the dark photo detection chamber is indicative of an indoor air quality.

Abstract: A method for calibrating indoor air quality (IAQ) sensors associated with an area of interest (AOI) is disclosed. The method comprises the steps of creating a predetermined calibration environment for one or more IAQ sensors associated with the AOI by enabling a building management system (BMS) associated with the AOI to perform one or more of adjusting inflow of outside air into the AOI to a first predetermined maximum level, adjusting ventilation rate of the AOI to a second predetermined maximum level, and increasing a degree of air filtration in the AOI to a third predetermined maximum level; monitoring IAQ values detected by the one or more IAQ sensors at the AOI in the predetermined calibration environment, and calibrating the one or more IAQ sensors based on an average value of the monitored IAQ values being detected by each of the IAQ sensors.

Abstract: Embodiments of the disclosure describe systems and methods for evaluating an operational aspect of a life safety detection device. The method comprises transmitting light from at least one light source into a detection chamber positioned within an interior of a housing of the device. Further, the method comprises receiving, over a predefined time period, scattered light within the detection chamber, wherein the scattered light is indicative of a presence of airborne particulate matter. Furthermore, the method comprises determining, by a processor coupled to the device, a variation pattern of the airborne particulate matter during the predefined time period to analyze, by the processor, the variation pattern of the airborne particulate matter over the predefined time period with respect to another variation pattern during the predefined time duration to evaluate operational aspects of the device.

Abstract: A method of calibrating a detector that includes a volatile organic compound (VOC) sensor is provided. The method includes assembling the detector with the VOC sensor for field deployment and calibrating the VOC sensor using carbon monoxide (CO) as a calibrant prior to the field deployment.

Abstract: An air monitoring system includes a housing having a housing inlet and a housing outlet. An airflow is configured to pass through the housing inlet into the housing. A sensor is located within the housing. The sensor is configured to monitor at least one of a frequency of dispensation of an air cleaner from an air freshener and a level of a contaminant in the airflow. The air cleaning system is configured to transmit a sensor signal to at least one of the air freshener and a user device to at least one of: recommend a frequency for air freshening, and adjust a frequency of release of the air cleaner from the air freshener.
