External Description
This section describes the housing and all external components of the
Beacon 200. For the purposes of this description, the housing door is
considered the front of the monitor.
Housing
The Beacon 200’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 screen 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. Three conduit hubs on the bottom of the
housing are for external wiring connections.
CAUTION: Only use the three facto ry installed condui t hubs on the bottom
of the housing for wire entry into the housing. Do not drill the
housing for any reason.
CAUTION: To avoid electrical interferen ce, do not r oute detec tor head a nd
power wiring thro ugh the same conduit hub.
Reset Switch
The reset switch is on the bottom of the housing. It is in front of the conduit
hubs. The reset switch serves three functions:
• Resets the alarm circuits for “latched” alarms after an alarm 1 or alarm 2
condition passes.
You can set each channel for latched or self-resetting alarms in the
Channel Control & Setup Program.
• 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. It is on the far right. The buzzer
sounds audible alarms to warn you of gas alarms and instrument failures.

housing body. Use the removable cap near the bottom of the housing body
to access the sensor for maintenance or replacement. The cap protects the
sensor from damage and includes a flame arrestor which contains any
sparks which may occur within the detector housing body. A cap gasket
seals the interface between the housing body and cap. A flame arrestor
guard is permanently bonded to the cap.
The calibration cup/splash guard is screwed onto the bottom of the flame
arrestor guard.
The sensor is secured within the sensor housing by four pins. Through a
series of chemical and electrical reactions, the sensor produces an
electrical output that corresponds to the detection range of the detector. A
pre-amplifier, located between the sockets and two interconnect wires,
conditions the sensor’s signal before the signal reaches the controller. A
rubber boot and spacer are installed on the sensor face to ensure that the
sensor remains plugged into the detector housing body.
AC Power Cord
An 8 foot AC power cord is factory-wired through the right cable bushing of
the Beacon 200. One end of the cable is connected to the AC In terminal
strip.

is mounted to the power supply mounting plate with four standoffs. The
main PCB includes the terminal strips, relays, fuses, and power switch.
Terminal Strips
The Beacon 200 includes four terminal strips for external wiring
connections. See “Wiring the Beacon 200” on page 17 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. 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. The H2S detectors are factory wired to
these terminal strips.
• 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 channels as
well as common alarm relay contacts. The horn/strobe is factory wired
to this terminal strip.
• 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.

strip (see Figure 1). These relays are dedicated to specific channels
and alarm levels.
For example, the channel 1, alarm 1 relay energizes if channel 1
recognizes an alarm 1 condition. Figure 4 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 “Configure Channel Settings Menu” on
page 34 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. The common alarm 1 relay
is factory wired to the strobe/horn and is not available for customer use.
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 at 3 A, 250 V.
• 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
72-2102-07 Beacon 200 Operator’s Manual • 12
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 at 6A, 250 V.
Power Switch
The power switch is located above the relays and to the left of the 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.
