65-2496RK/65-2499RK CO Detector

Overview

This manual describes the 65-2499RK carbon monoxide (CO) detector. This manual also
describes how to install, start up, maintain, and calibrate the CO 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 detector.

The 65-2499RK CO detector includes the 65-2496K CO detector and a junction box. This
manual may also be used for the 65-2496RK CO detector which does not include a
junction box and is normally mounted in one of a controller’s conduit hubs. If yo u are
using a 65-2496RK CO detector, disregard all references to the junction box and junction
box terminal strip.
