Agent detection system assisted by a building subsystem
Abstract:
An indoor air quality monitoring system (20) is adapted to function within a space (26) utilizing a building subsystem (22), such as a heating ventilation air conditioning (HVAC) unit, configured to control an ambient parameter, such as temperature, humidity or lightning, in the space (26). The system (20) includes an agent detector (30) configured to detect an agent in ambient air, such as smoke, biohazards or particulate matter, and sequentially output an initial agent measurement signal and a subsequent agent measurement signal. A controller (34) of the system (20) includes a processor and a storage media. The controller (34) is pre-programmed with an agent threshold value, and configured to receive the initial agent measurement signal, compare the signal to the agent threshold value, and if the signal exceeds the agent threshold value, then send a command signal (42) to the subsystem (22) to alter the ambient parameter associated with the agent detector, and then receive the subsequent agent measurement signal from the agent detector associated with the altered ambient parameter.
