65-2300RK/65-2301RK Toxic Detector • 1
Overview
This manual describes the 65-2301RK toxic detector. This manual also describes how to
install, start up, maintain, and calibrate the toxic detector when used with a gas
monitoring controller. A parts list at the end of this manual lists replacement parts and
accessories for the toxic detector.
The 65-2301RK toxic detector includes the 65-2300RK toxic detector and a junction box.
This manual may also be used for the 65-2300RK toxic detector which does not include a
junction box and is normally mounted in one of a controller’s conduit hubs. If you are
using a 65-2300RK toxic detector, disregard all references to the junction box and junction
box terminal strip.
The 65-2300RK and 65-2301RK detectors can be used for various target gases which are
listed in Table 1 below. For a particular target gas, the part number of the toxic detector
will be of the format 65-2300RK-XXX or 65-2301RK-XXX. For example, 65-2301RK-NH3 is
for ammonia (NH
3
) detection.
