Abstract: Disclosed is an electromagnetic interference (EMI) cover for a gas detector including one or more electrical components. The EMI cover includes one or more cover layers, each cover layer including a plastic material layer and one or more layers of conductive or dielectric ink applied to the plastic material layer defining one or more conductive pathways. The one or more conductive pathways are positioned in a pattern to provide electromagnetic interference (EMI) shielding to the one or more electrical component.

Abstract: A cap for a light emitter and/or light receiver of a smoke detector for eliminating a direct line of sight between the light emitter and the light receiver is disclosed. The cap comprises an enclosure of a predefined profile having a predetermined open area at a predetermined position on the enclosure, which is adapted to be removably fitted over one or more of the light emitter and/or the light receiver. The cap upon fitting over any of the light emitter and the light receiver, the cap blocks a direct line of sight between the light emitter and the light receiver and allows the light receiver to receive only the light being reflected by smoke and a predefined amount of clean air signal present within the smoke detector.

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.
