Dec 13, 2017.The code requirements for emergency control of HVAC systems is found in Section 21.7 of the 2016 edition of NFPA 72, where it states that the rovisions of Section 21.7 shall apply to the basic method by which a fire alarm system interfaces with the heating, ventilating, and air conditioning (HVAC) system.
The Fire and Smoke Map shows fine particulate (2.5 micron, PM 2.5) pollution data obtained from air quality monitors and sensors.Information is shown on both the EPA Air Quality Index scale, using the NowCast AQI algorithm, and also as hourly PM 2.5 concentration values. For low-cost sensor data, a correction equation is also applied to mitigate bias in the sensor data.
