External Description
This section describes the housing and all external components of the 12
VDC Beacon 200. For the purposes of this description, the housing door is
considered the front of the monitor.
Housing
The 12 VDC Beacon 200’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.
