Installation
This section describes procedures to mount the CO
2
detector in the monitoring
environment and wire it to a controller. If you purchased a 61-0191RK detector that is
factory installed in and factory wired to a controller, detector installation is not necessary.
Mounting the CO
2
Detector
1. Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
Select a site where the detector is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration
procedures.
Select a site where the target gas is likely to be found first.
Select a site that minimizes the possibility of someone breathing on the detector.
The exhaled CO
2
may cause an alarm.
