Chapter 3: Installation and Start Up
Overview
This chapter describes procedures to mount the Beacon 200 Gas Monitor,
make wiring connections to the monitor, and start up the monitor.
WARNING: Perform all installation and start-up procedures in a
“fresh air” environment (known to be free of combustible
gas, toxic gas, and of normal oxygen content). The
Beacon 200 is not in operation as a gas monitoring
system until the start-up procedure is complete.
Mounting the Beacon 200 Gas
Monitor
Perform the following procedure to install the Beacon 200 at the mounting
site.
1. Select the mounting site. When you select the mounting site consider
the following factors:
• Is an AC or DC power source available?
• Is there enough room to open the housing door and make wiring
connections through the conduit hubs at the bottom of the housing?
• Are the display screen and status lights visible?
2. Close and latch the housing door.
3. Position the monitor on a vertical surface at eye level (4 1/2 to 5 feet
from the floor).
4. The Beacon 200 is shipped with the mounting feet positioned behind
the housing. Loosen the screws that secure the feet to the housing,
rotate the feet to their mounting position (as shown in Figure 4), then
tighten the screws.
5. Insert 1/4 in. or 5/16 in. screws through the slots in the mounting feet at
each corner of the housing to secure the housing to the mounting
surface (see Figure 4).
