Overview
This manual describes the 65-1004RK CO
2
(carbon dioxide) detector. This manual also
describes how to install, start up, maintain, and calibrate the detector when used with a
gas monitoring controller. A parts list at the end of this manual lists replacement parts and
accessories for the CO
2
detector.
The 61-1004RK CO

the 61-0191RK CO
2
detector which does not include a junction box and is normally
mounted in one of a controller’s conduit hubs and factory wired to the controller. If you
are using a 61-0191RK CO
2
detector, disregard all references to the junction box and
junction box terminal block.
