61-1004RK/61-0191RK Carbon Dioxide Detector • 1
Overview
This manual describes the 61-1004RK 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
2
detector includes the 61-0191RK detector and a junction box. This
manual may also be used for 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.
Specifications
Table 1 lists specifications for the CO
2
detector.
