External Description
This section describes the housing and all external components of the
Beacon 200 Rig Monitor. For the purposes of this description, the housing
door is considered the front of the monitor.
Housing
The Rig Monitor’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 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. Three conduit hubs on the bottom of the
housing are for external wiring connections.
CAUTION: To avoid electrical interference, do not route detector head and
power wiring through the same conduit hub.
Reset Switch
The reset switch is on the bottom of the housing. It is in front of the conduit
hubs. 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 Control & Setup Program.
• 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. It is on the far right. The buzzer
sounds audible alarms to warn you of gas alarms and instrument failures.
