Beacon 110 Rig Monitor Operator’s Manual

External Description
This section describes the housing and all external components of the Beacon 110 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 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 cable bushings
on the bottom of the housing are for wiring connections. One cable bushing is for the 12 VDC
battery connection. The other is for the direct connect H
2
S detector connection. Both are factory
wired.
CAUTION:
Only use the two factory installed conduit hubs on the bottom of the housing for
wire entry into the housing. Do not drill the housing for any reason. See “Routing
Wiring Into the Beacon 110 Housing” on page 14 for more information.
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 four
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 turn off the strobe/horn in an alarm 1 condition once the condition has passed.
•
You can display and reset the minimum and maximum readings that the Rig Monitor has
experienced since the last min/max reset or startup.
Alarm Strobe/Horn
The Rig Monitor has a red alarm strobe light/horn installed on the top of the housing. The Rig
Monitor retains its NEMA 4X rating with the strobe installed. Strobe/horn operation is controlled
by the Alarm 1 relay contacts. The relay action settings can be changed in Configuration Mode.
