The AtmosComms2 module is connected via Cat5e cable to the AtmosSmart™ sensor array.
Warning: Contractor must use the specified AtmosAir Cat5e cable. No substitutions are allowed.
Typically, the 500 Series or Matterhorn Series are either mounted in the supply duct, transition duct, or on racks or mounts
within the Air Handling Unit. Note: See AtmosAir 500 Series or Matterhorn Series IOM for detailed AtmosAir system installation
instructions.
Warning: Verify this is a well-grounded branch dedicated circuit.
All the 500 series BPI systems are wired to dedicated well-grounded 15-amp, 110-125 Vac 50 Hz or 120 Vac 60Hz service via a
dedicated, well-grounded junction box. This circuit should be electrically protected from floating grounds and erroneous voltage
spikes, such as surges and sags.
The AtmosSmart™ sensor array and AtmosComms2 control system derive their operational power from the same main field wired
circuit providing power to the AtmosAir 500 Series or Matterhorn series. (Refer to warning note above).
The sensor head reads multiple indoor air quality (IAQ) data-sets in real time by sensing air properties in the Return Air system.
This configuration allows the sensor to adjust IAQ based on demand, observing contaminants, humidity, and occupancy every few
seconds.
The Bi-polar Ionization power, ionization output and duration are based on these readings and decisions made using AtmosAir
proprietary algorithms. Bandwidth decision time, algorithms and operational parameters are tailored and customized in AtmosAir
facilities to the final customer’s application.
Typically, every 30 seconds, an average of readings is taken. As the AtmosSmart sensor is read, that value goes into an AtmosAir
proprietary algorithm. Every (2) minutes the ‘decision engine’ makes a go/no-go evaluation based on pre-programmed set points.
Three ‘decisions’ are made within one standard air exchange. Every 6 minutes, AtmosSmart performs an ‘air exchange calculation.’
A coarse debris screen is installed on the impeller sensor port. The internal fan in the AtmosSmart™ Sensor Array assures
continuous metering and sampling of the air and the space in front of the screen should not be obscured or restricted. The sensor
should not be subjected to condensing moisture nor temperatures exceeding the range of 30 °F to 120 °F (-1 °C to 49 °C).
