Chapter 2: Description

Overview

This chapter describes external and internal components of the Beacon 100 Gas Monitor.

External Description

This section describes the housing and all external components of the Beacon 100. For the
purposes of this description, the housing door is considered the front of the monitor.

Housing

The Beacon 100’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 a window 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. Two conduit hubs on the bottom of the housing are for
external wiring connections. (In some cases, the instrument is shipped with the gas
detector already attached to one of the wiring hubs and factory wired to the appropriate
terminals inside the unit.)

CAUTION: To avoid electrical interference, do not route detector and power wiring through the

same conduit hub.

Buzzer

The buzzer is on the bottom center of the housing in front of the reset switch. The buzzer
sounds audible alarms to warn you of gas alarms and instrument failures.

Reset Switch

The reset switch is on the bottom of the housing behind the buzzer. The reset switch
serves two functions:

• You can reset the alarm circuits for “latched” alarms after an alarm 1, alarm 2, or
alarm 3 condition passes.

• You can silence the buzzer during an alarm 1 condition. You cannot silence alarm 2,
alarm 3, or failure alarms.

Fuses

The Beacon 100 includes one AC fuse (0.5 amp) and one DC fuse (1.5 amp).

AC fuse

The AC fuse holder is underneath the display board on the left hand side near the left
edge of the main circuit board. The AC fuse protects the AC line circuitry from short
circuit or overload. The AC fuse is rated at 0.5 amps.

NOTE: The standard configuration is for 115 VAC operation. 220 VAC operation is an

optional configuration and must be specified when ordering.

DC fuse

The DC fuse is located underneath the display board on the right hand side (near the right
edge of the main circuit board). The DC fuse protects the DC line circuitry from short
circuit or overload. The DC fuse is rated at 1.5 amps.

Transformer

The transformer is at the center top of the PC Board (under the display screen). The
transformer receives the incoming AC voltage and converts it to a nominal DC voltage.

Terminal Strips

The Beacon 100 includes three terminal strips for external wiring connections. They are
located on the lower section of the main PC board just above the incoming wiring hubs,
and to the left and right edges of the main circuit board about in the middle. See Chapter
3, Installation and Start Up, for wiring procedures.

Input power terminal strip

The input power terminal strip is located below the display board on the left hand side of
the main PCB. The top three terminals are for AC power connections and ar e labeled “AC
POWER IN” on the main circuit board.

The bottom two terminal positions are for DC power connections and are labeled “12
VDC IN” on the main circuit board.

External alarm terminal strip

The 12-point external alarm terminal strip consists of the 12 left hand terminals on the
lower terminal strip located just above the wiring hubs on the bottom of the enclosure.
You connect wiring from external alarms (if applicable) to the external alarm terminal
strip. This terminal strip has common (C), normally closed (NC) and normally open (NO)
terminals for alarm 1, alarm 2, and alarm 3 connections, and also for FAIL condition.
These terminals are clearly marked on the PC board

Detector terminal strip

The 7-point detector terminal strip (Labeled 1 through 6) is directly to the right of the
external alarm terminals on the lower terminal strip. You connect wiring from the detector
head to the detector terminal strip. T erminals labeled 1, 2, 3, and 4, ar e for the wiring to the
detector head. These are also labelled “RED, WHITE, GREEN, BLACK” to correspond to
the sensor wire colors on certain sensor types. Terminals 5 and 6 are for connection of the
oxygen detector head and are labelled OXY+ and OXY -.
