Appendix G: Infrared Carbon Dioxide Sensors
Overview
The infrared CO
2
sensors are used to monitor levels of carbon dioxide. This appendix
describes the EAGLE 2’s infrared CO
2
sensors and includes instructions to use an EAGLE
2 that has one or more infrared CO
2
sensors installed. It also includes instructions to
replace an infrared CO
2
sensor.
Table 23: Infrared CO
2
Sensor Specifications
Description
Table 23 above lists the available infrared CO
2
sensors. The infrared CO
2
sensor is a smart
sensor that stores sensor parameters including the target gas and detection range. So you
can change an existing infrared CO
2
channel from one range to another and the EAGLE 2
will automatically load all the sensor parameters and configure the infrared CO
2
channel
for the new sensor without the need to enter CONFIGURE CHANNELS or CONFIGURE
GASES in Setup Mode. See “Replacing the IR CO
Sensor or Changing Sensor Type” on
page 211 for instructions to replace or change an infrared CO
2
sensor.
