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 22: Infrared CO
2
Sensor Specifications
Description
Table 22 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
2
Sensor or Changing
Sensor Type” on page 237 for instructions to replace or change an infrared
CO
2
sensor.
