Chapter 2: Description
Overview
This chapter describes external and internal components of the Beacon 800 Gas Monitor.
External Description
This section describes the housing and all external components of the Beacon 800. For
the purposes of this description, the housing door is considered the front of the monitor.
Housing
The Beacon 800’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 screens 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. Four conduit hubs on the bottom of the housing are for
external wiring connections.
CAUTION: To avoid electrical interference, do not route transmitter and power wiring
through the same conduit hub.
Reset Switch
The reset switch is on the bottom of the housing, in front of the buzzer. 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 setup pro-
gram. See Chapter 5, Configuration, for more information.
• 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, behind the reset switch. The buzzer sounds
audible warnings to warn you of gas alarms and instrument failures.
