BAPI CO2 Duct Installation & Operating Instructions

28173_ins_CO2_Duct
Identification and Overview
The BAPI CO Duct Sensor is an accurate and reliable way
2
of incorporating demand controlled ventilation. It measures
CO in ranges of 0 to 2,000, 0 to 5,000, 0 to 10,000 and 0
2
to 50,000 ppm with a field selectable output of 0 to 5 or 0 to
10 VDC.
The Single Beam (ACD) unit has been optimized for
periodically unoccupied areas and features automatic
background calibration over a long time period to reduce
drift. The Dual Channel (DCD) "24/7" unit has been
optimized for continuously occupied areas and features a
3-point calibration process.

Installation & Operating Instructions
Barometric pressure changes from altitude or weather
can affect CO sensors, even putting them outside of their
2
specified accuracy. The BAPI unit has a built-in Barometric
pressure sensor that continuously compensates the output
for accurate readings despite the weather or altitude.
The Duct unit samples duct air using an aspiration tube.
The Rough Service unit features a ventilated BAPI-Box and
is ideal for areas such as outdoor air plenums, equipment
rooms, attics, green houses and warehouses. Optional
indication of the CO
2
available as a 3-color LED for 0 to 2,000 ppm range units.
