Chapter 2: Description
Overview
This chapter describes external and internal components of the Beacon 800 Gas Monitor.
External Description
This section describes the housing and all external components of the Beacon 800. For
the purposes of this description, the housing door is considered the front of the monitor.
Housing
The Beacon 800’s fiberglass housing is weather- and corrosion-resistant. It is suitable for
installation where general purpose equipment is in use. The housing door is hinged on the
left side and is secured by two latches on the right side. The display screens and status
lights are visible through windows in the housing door. Four mounting feet are attached to
the back of the housing (one at each corner). The mounting feet allow you to install the
housing to a vertical surface. Four conduit hubs on the bottom of the housing are for
external wiring connections.
CAUTION: To avoid electrical interference, do not route transmitter and power wiring
through the same conduit hub.
Reset Switch
The reset switch is on the bottom of the housing, in front of the buzzer. The reset switch
serves three functions:
• Resets the alarm circuits for “latched” alarms after an alarm 1 or alarm 2 condition
passes.
Y ou can set each channel for latched or self-resetting alarms in the channel setup program. See Chapter 5, Configuration, for more information.
• Silences the buzzer during an alarm 1 or alarm 2 condition. You cannot silence failure
alarms.
• Displays and resets the minimum and maximum gas concentration values.
Buzzer
The buzzer is on the bottom of the housing, behind the reset switch. The buzzer sounds
audible warnings to warn you of gas alarms and instrument failures.

The FAIL light turns on when the Beacon 800 is experiencing a fail condition. A fail
condition can be caused by a failure within the Beacon 800 or transmitter(s) wired to the
Beacon 800 (see “Chapter 6: Maintenance” on page 29).
ALARM 1 Light
The ALARM 1 light is on when the Beacon 800 is experiencing a low-level (alarm 1) or
high-level (alarm 2) gas condition.
ALARM 2 Light
The ALARM 2 light is on when the Beacon 800 is experiencing a high-level (alarm 2) gas
condition.
Program Buttons
The Beacon 800 includes four program button that allow you to enter the Configuration
Menu, navigate through the menu, update instrument and channel settings, and save
changes to the settings. The program buttons, listed in Table 2, are near the right edge of
the display board (see Figure 2).

Ground Stud
The ground stud is used for connecting earth ground to the Beacon 800. The ground stud
is factory wired to the GND terminal on the AC terminal strip. The ground stud is located in
the lower right corner of the main board.
Terminal Strips
The Beacon 800 includes four terminal strips for external wiring connections. See “Wiring
the Beacon 800 Gas Monitor” on page 12 for detailed wiring procedures.
Transmitter Terminal Strips
Two transmitter terminal strips are mounted to the bottom left corner of the main circuit
board (see Figure 1). These two 12-point terminal strips facilitate wiring connections to the
detector heads. The bottom terminal strip is for channels 1 through 4; the top terminal strip
is for channels 5 through 8.
Alarm Terminal Strips
Four alarm terminal strips are to the right of the transmitter terminal strips (see Figure 1).
These four 12-point terminal strips facilitate wiring connections to external alarm devices
(horn, strobe, etc.). The bottom row of alarm terminals is for alarm 1 connections; the top
row of alarm terminals is for alarm 2 connection.
NOTE: The alarm terminal strips provide external alarm connections controlled by
individual channels. The Beacon 800 also provides common alarm terminals on
the controller terminal strip. The common alarm terminals are controlled by all
active channels.
Controller Terminal Strip
The 19-point controller terminal strip is to the right of the alarm terminal strips (see Figure
1). The controller terminal strip facilitates various internal and external wiring connections.
Table 3 lists the function of each terminal.

AC Terminal Strip
The 3-point AC terminal strip is above the controller terminal strip (see Figure 1). The AC
terminal strip facilitates wiring connections to the AC power source. The GND terminal is
factory wired to the ground stud.
Relays
The Beacon 800 includes 16 channel relays and three common relays. Both sets of relay
contacts are single-pole, double-throw (SPDT) and are rated for 3 amps at 115 VAC
(resistive).
NOTE: In the Configuration menu, you can select normally energized, or normally de-
energized relays for each channel relay. This section describes the default
setting: normally de-energized.
The alarm 1 and alarm 2 common relays are factory-set as normally deenergized and the fail common relay is factory-set as normally energized. The
normally energized/normally de-energized setting for the alarm 1, alarm 2, and
fail common relays is not user-adjustable.
Channel Relays
The 16-channel relays are above the alarm terminal strips (see Figure 1). These relays
are dedicated to specific channels and alarm levels.
7 • Internal Description Beacon 800 Gas Monitor Operator’s Manual
For example, the channel 1, alarm 1 relay energizes if channel 1 recognizes an alarm 1
condition. Figure 3 illustrates the allocation of the channel relays.

Channel 8
Common Relays
The three common relays are above the AC terminal strip (see Figure 1). These relays are
common for all channels.
For example, the alarm 1 common relay energizes if any channel recognizes an alarm 1
condition.
Power Switch
The power switch is to the left of the fuses (see Figure 1). The power switch turns the
incoming power source on and off at the Beacon 800. When the switch is up, the power is
on.
Power Supply
The power supply is near the top edge of the main circuit board. The power supply
receives the AC input from the external power source and converts it to a DC voltage that
is usable by the Beacon 800 circuitry.
Fuses
The Beacon 800 includes two AC fuses and one DC fuse. The fuses are housed in
extractor-type fuse holders behind the display board and to the left of the common relays.
• The AC fuses are the two 3A fuses. The AC fuses protect the AC line circuitry from
short circuit or overload.
• The DC fuse is the 6A fuse. The DC fuse protects the DC line circuitry from short
circuit or overload.
NOTE: If your Beacon 800 includes the optional Recorder Output Board or the Heavy
Duty Relay Board, please see “Chapter 7: Optional Recorder Output Board &
Heavy Duty Relay Board” on page 32 for a complete description of these options.

Chapter 3: Installation and Start Up
Overview
This chapter describes procedures showing how to mount the Beacon 800 Gas Monitor, to
make wiring connections to the monitor, and to start up the monitor.
WARNING: Perform all installation and start-up procedures in a “fresh air”
environment of normal oxygen content, and known to be free of
combustible and toxic gas. The Beacon 800 is not in operation as a
gas monitoring system until the start-up procedure is complete.
Mounting the Beacon 800 Gas Monitor
Perform the following procedure to install the Beacon 800 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 screens 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 800 is shipped with the mounting feet positioned under 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. 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).
