Chapter 1: Introduction
Overview
This chapter briefly describes the Beacon 200 Gas Monitor. This chapter
also describes the Beacon 200 Gas Monitor Operator’s Manual (this
document). Table 1 at the end of this chapter lists the specifications for the
Beacon 200.
About the Beacon 200 Gas Monitor
The Beacon 200 is a fixed-mounted, continuous-monitoring gas detection
instrument. This gas monitor is capable of detecting gas at up to two
locations. The display screen simultaneously displays the gas readings of
the active channel or channels. Both direct connect (internal amplifier type)
detector heads and 4 - 20 mA transmitter (remote amplifier type) detector
heads may be used with the Beacon 200.
NOTE: If any of the Beacon 200’s channels have been set up for
hydrogen-specific LEL operation, that channel or channels can
only be used with a hydrogen-specific sensor. If you want to detect
a different combustible gas or use a different detector, the Beacon
200 must be sent back to RKI Instruments, Inc. for modification.
The Beacon 200 includes audible and visual alarms that warn you of
hazardous gas conditions. The alarm circuit includes two levels of gas
alarms. The fail circuit alerts you to failures in the gas detector heads or
Beacon 200.
Three instrument programs allow you to display and change channel and
calibration settings and change channel types. They are the Channel
Control & Setup Program, the Calibration Program, and the Input Setup
Program.

Main PCB
The main PCB is mounted inside the housing. The power supply mounting
plate is mounted to the main PCB with four standoffs and the display PCB
is mounted to the power supply mounting plate with four standoffs. The
main PCB includes the terminal strips, relays, fuses, and power switch.
NOTE: If any of the Beacon 200’s channels have been set up for
hydrogen-specific LEL operation, the main PCB for that channel
or channels has been modified and can only be used with a
hydrogen-specific sensor. If you want to detect a different
combustible gas or use a different detector, the Beacon 200 must
be sent back to RKI Instruments, Inc. for modification.
Terminal Strips
The Beacon 200 includes four terminal strips for external wiring
connections. See “Wiring the Beacon 200 Gas Monitor” for detailed wiring
procedures.
• Detector/Transmitter Terminal Strips. Two detector/transmitter
terminal strips are located near the bottom left corner of the main circuit
board (see Figure 1). These two 9-point terminal strips facilitate wiring
connections to the detectors or transmitters. Although each terminal
strip can accommodate several different detector head models, only
one detector head at a time may be wired per channel. The top terminal
strip is for channel 1 and the bottom terminal strip is for channel 2.
• Alarm Terminal Strip. The alarm terminal strip is located along the
bottom edge of the main circuit board (see Figure 1). This 21-point
terminal strips facilitates wiring connections to external alarm devices
(horn, strobe, etc.). Terminals are provided for individual channel as
well as common alarm relay contacts.
• Controller Terminal Strip. The 10-point controller terminal strip is near
the lower right edge of the main circuit board (see Figure 1). The
controller terminal strip facilitates various internal and external wiring
connections. Table 3 lists the function of each terminal.

located above the controller terminal strip (see Figure 1). It facilitates
wiring from the AC power source. Table 4 lists the function of each
terminal.
Table 4: Terminal Assignments for the AC In Terminal Strip
Terminal Connects to:
LINE Hot wire from AC power source.
NEUT Neutral wire from AC power source.
NOTE: The AC power source’s ground wire must be connected to the
ground stud. See “Connecting the AC Power Source” on page 20
for instructions.
Relays
The Beacon 200 includes four channel relays (two per channel) and three
common relays. Both sets of relays are single-pole, double-throw (SPDT)
and are rated for 10 amps at 250 VAC (resistive).
NOTE: You can select normally energized (NE) or normally de-energized
(NDE) settings for each channel in the Channel Control and Setup
program. This section describes the default setting: normally deenergized.
The alarm 1 and alarm 2 common relays are factory-set as NDE
and the fail common relay is factory-set as NE. The alarm 1, alarm
2, and fail common relays’ NE/NDE settings are not useradjustable.
• Channel Relays. The four channel relays are above the alarm terminal
strip (see Figure 1). These relays are dedicated to specific channels
and alarm levels.

recognizes an alarm 1 condition. Figure 3 below illustrates the
allocation of the channel relays.
NOTE: The alarm 2 channel relays may be set to operate as individual
channel fail relays. See the Configure Channel Settings section of
Chapter 5 for instructions.
• Common Relays. The three common relays, alarm 1, alarm 2, and fail,
are to the left of the controller terminal strip (see Figure 1). These relays
are common for both channels.
For example, the alarm 1 common relay energizes if either channel 1 or
channel 2 recognizes an alarm 1 condition.
Fuses
There are three fuses that are used in the Beacon 200. Two of them are AC
fuses and one of them is a DC fuse.
• AC Fuses. The two fuses located directly to the left of the controller
terminal strip are the AC fuses. They cut off the incoming AC power in
the event of a short circuit or other electrical fault which causes a high
current draw in the Beacon 200. They are housed in vertical fuse
holders and are held in the holder by a quarter turn cover. They are
labelled as F2 (top fuse) and F3 (bottom fuse) on the PCB silk-screen
and are rated to 3 A, 250 V, 1/4 x 1 1/4”, fast acting.
• DC Fuse. The fuse located to the left of the power switch is the DC
fuse. It cuts off incoming DC power in the event of a short circuit or
other electrical fault which causes a high current draw in the Beacon
200. It is also housed in a vertical fuse holder and is held in the holder
by a quarter turn cover. It is labelled as F1 on the PCB silk-screen and
is rated to 6A, 250 V, 1/4 x 1 1/4”, fast acting.
Internal Description • 15
Power Switch
The power switch is located above the relays and in between the AC and
DC fuses (see Figure 1). The power switch turns the incoming AC power
source on and off at the Beacon 200. When the switch is up, the power
switch is on.
NOTE: The DC power input has no on/off switch and is not affected by the
position of this switch.
Power Supply
The power supply is mounted to the power supply mounting plate which is
located behind the display PCB. The power supply mounting plate is
mounted to the main PCB with four standoffs. 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 200 circuitry.
