Application,
Continued
The QPA20xx Series Room Sensors can be used as:
• Control sensors.
• Transmitters for building automation and control systems and/or display units.
Typical use:
• Acquisition of CO
2
and VOC concentrations:
In party rooms, lounges, fair pavilions and exhibition halls, restaurants, canteens,
shopping malls, sports gymnasiums, sales rooms, and conference rooms.
• Acquisition of CO
2
concentrations:
In rooms with varying occupancy levels where smoking is prohibited, such as
museums, theaters, movie theaters, auditoriums, office spaces, and school rooms.
NOTES:
• The QPA20xx Series Sensors are not designed for use as safety devices,
such as gas or smoke warning devices.
• Do not install outdoors.

Equipment
Combinations
QPA20xx Series Sensors can be used with all types of systems and devices capable of
acquiring and handling the 0 to 10 Vdc output signal delivered by the sensor.
Mode of Operation
CO
2
Concentrations
The QPA20xx Series Air Quality Sensors acquire the CO
2
concentration by infrared
absorption measurement (NDIR). Due to an additional integrated reference light
source, the measurement is always accurate. This reduces service costs as no service
or recalibration is needed. The sensor acquires and evaluates the CO
2
concentration.
The resulting output signal is proportional to the CO
2
content of the ambient air.
