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.
