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 yo u 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- 230 0RK -X XX or 65 -23 01 RK-XXX. For example, 65-2301 RK -N H3 is
for ammonia ( NH
