Chapter 3: Installation
Overview
This chapter describes how to install the RI-215A at the monitoring site. This section also
includes procedures to make power and other wiring connections to the RI-215A.
Mounting the RI-215A
CAUTION: The RI-215A is suitable for installation in indoor areas where general purpose
equipment is in use.
1. Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site:
• Select a site near the sampling area in which the RI-215A is not likely to be
bumped or disturbed.
• Choose a location not subject to significant air movement, for example, near an air
conditioning or heating vent.
• Mount the RI-215A in an area not subject to large temperature and humidity
changes.
• Mount the RI-215A on the wall at least six feet from the floor to minimize the
possibility of someone breathing on the unit. The exhaled CO
2
may cause an
alarm.
• Make sure there is sufficient room to make wiring connections through the back
of the unit, and to remove the unit from the base plate to perform maintenance,
such as replacing the fuse.
2. For wall-mounting, remove the base plate of the RI-215A.
• Using a small screw driver, press down on the small tab on top of the
Model RI-215A.
• While pushing down on the tab, gently move the base plate away from the front
housing of the RI-215A.
CAUTION: Be very careful not to pull on the cable assembly connected to the RI-215A’s internal
printed circuit board when removing the base plate. Pulling on the cable assembly
may damage the printed circuit board.
• Completely separate the base plate from the front housing.
