Chapter 2: Description
Overview
This chapter describes external and internal components of the Beacon 110 gas monitor.
External Description
This section describes the housing and all external components of the Beacon 110. For
the purposes of this description, the housing door is considered the front of the monitor.
Housing
The Beacon 110’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 installation 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
installed in the right conduit hub 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 three functions:
• You can reset the alarm circuits for “latched” alarms after an alarm 1 or alarm 2
condition passes.
• You can silence the buzzer during an alarm 1 or an alarm 2 condition. You cannot
silence a fail condition.
• You can acknowledge and turn off the optional strobe in an alarm 1 or alarm 2
condition if it has been installed and setup for this type of operation.
• You can display and reset the minimum and maximum readings that the Beacon 110
has experienced since the last min/max reset or startup.
