The 12 VDC Beacon 200 includes four terminal strips for ext ernal wiring
connections. See “Wi ring the 12 VDC B eac on 20 0” on p a ge 13 for detailed
wiring procedures.
• Detector/Transmitter Terminal Strips. Two detector/transmitter
terminal strip s are locate d near the bo ttom lef t corne r of the mai n 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 h ead at a time ma y be wi red per channel . The top term inal
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 channels as
well as common alarm relay contacts.
• Controller T e rminal S trip. The 10-point controller terminal strip is near

Relays
The 12 VDC Beacon 200 includes four channel relays (two per channel)
and three common rela ys. Both sets of rela ys are single-p ole, double-thro w
(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 ea ch channel in th e Channel Co ntrol 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.
For example, the channel 1, alarm 1 relay energizes if channel 1
recognizes an alarm 1 condition. Figure 2 below illustrates the
allocation of the channel relays.

12 VDC Beacon 200 Operator’s Ma nual • 9
NOTE: The alarm 2 channel relays may be set to operate as individual
channel fail relays. See “Configure Channel Settings Menu” on
page 30 for instructions.
• Common relays. The three common relays , alarm 1, alarm 2, and fail,
are to the lef t of th e controlle r terminal strip (see Figu re 1). These rela ys
are common for both channels.
For example, the al arm 1 common rela y energizes if either channel 1 or
channel 2 recognizes an alarm 1 condition.
Fuses
There are two DC fuses that are used in the 12 VDC Beacon 200. They are
located directly to the left of the controller terminal strip. They cut off the
incoming DC power in the event of a short circuit or other electrical fault
which causes a high current draw in the 12 VDC 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.
A third fuse located to the left of the power switch is labelled F1. This fuse
is not used in this version of the Beacon 200.
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 DC power source on
and off at the 12 VDC Beacon 200. When the switch is up, the power
switch is on.
Power Converter
The power converter is mounted to the power supply mounting plate with
standoffs. The power supply mounting plate is located behind the display
PCB and is mounted to the main PCB with fo ur standoffs. The power
converter takes 12 VDC voltage supplied to the 12 VDC Beacon 200 and
converts it to 24 VDC which is used to run the 12 VDC Beacon 200.

Overview
This chapter describes the 12 VDC Beacon 200 in normal operation. This
chapter also describes the 12 VDC Beacon 200 in alarm 1, alarm 2, and fail
conditions and suggests response to these conditions.
Normal Operation
Normal operation is defined as follows:
• The start-up procedure is complete.
• The 12 VDC Beacon 200 is not indicating an alarm 1, alarm 2, or fail
condition.
• The 12 VDC Beacon 200 is not running the Channel Control & Setup or

12 VDC Beacon 200 Operator’s Manual • 21
Recorder Output Operation
The output at the recorder output terminals is a 4 - 20 mA signal for each
active chann el that is proportional to the detection range of the channel. A
channel that is set as CHANNEL NOT USED or CHANNEL DISABLED in
the Channel Control & Setup Program (see “Chapter 5: Channel Control
and Setup Program” on page 28) has an output of 0 mA.
There are several special circumstances where the recorder output will
behave as follows:
• When a channel is in WARMUP after the 12 VDC B eacon 200 i s tu rned
on, the recorder output will be at 4 mA.
• If the 12 VDC Beacon 200 is being powered by a battery and is in low
battery alarm, the recorder output for each channel will b e 0 mA.
• When a channel is added or a channel type change d, the display will
indicate NEEDS CALIBRATION for that channel when the 12 VDC
Beacon 200 is first turned on and will cont inue to indicate this until the
channel is calibrated. In this situation, the recorder output will be at 3.2
mA until the channel is calibrated.
• If a channel goes into a fail condition, the recorder output will be 0 mA.
• If you enter any of the instrument programs, such as the Calibration
Program, the recorder output will hold at the value it was at when you
entered the program was entered until you return to normal operation.

View System Information Menu
The View System Information Menu consists of only one display screen
which indicates the version number of the firmware that is running the
instrument and the system voltage. The system voltage is the voltage that
is directly runnin g the instrument’ s circuitr y. Although 12 VDC is supplied to
this version of the Beacon 200, the system voltage will typically indicate 24
VDC because of the 12 VDC to 24 VDC converter in the 12 VDC Beacon
200.
The zero suppression feature helps prevent “jumpy” readings near the
fresh air reading.
For example, if the zero suppression setting on a %LEL channel is
and the full scale is 100% LEL, the 12 VDC Beacon 200 will display a
reading of 0% LEL for gas readings from -2% LEL to 2% LEL.

Chapter 7: Maintenance
Overview
This chapter describes use of the Calibration Program and corrective
maintenance procedures for the 12 VDC Beacon 200. It includes a
troubleshooting guide for problems you may encounter with the 12 VDC
Beacon 200. Procedures to replace components of the 12 VDC Beacon
200 are at the end of this chapter.
Calibration Program
The Calibration Program is used to calibrate the 12 VDC Beacon 200’s
active channel(s). Since the 12 VDC Beacon 200 can support both direct
connect (internal amp) and 4-20 mA transmitter (remote amp) detector
heads, when calibrating the a ctive channel(s) there are three possible
detector head combinations:
• Direct connect detector head(s) only.
If one or two direct connect detector heads are active, then all
calibration adjustments are made at the 12 VDC Beacon 200 after
calibration gas is applied at the detector(s).
• 4-20 mA transmitter detector head(s) only.
If one or two 4-20 mA transmitter detector heads are active, then all
calibration adjustments are made at the detector head(s) after
calibration gas is applied to the detector(s).
• A direct connect and a 4-20 mA transmitter detector head.
If one direct connect and one 4-20 mA transmitter detector head are
installed, then calibration adjustments must be made at the 12 VDC
Beacon 200 for the direct connect detector head after applying gas to
its detector, and at the detector head for the 4-20 mA transmitter
detector head.
Calibration Program Flow
Figures 11, 12, and 13 below illustrate the general flow of the Calibration
Program for the three possible detector head combinations. See the next
section, Entering the Calibration Program, for instructions to enter the
Calibration Program. In general, the program screens provide instructions
12 VDC Beacon 200 Operator’s Manual • 37
to guide you through the program. At any point in the calibration program,
the ESCAPE key may be used to either return to the previous screen or
abort a process.
