Chapter 4: Operation
Overview
This chapter describes the Beacon 100 Gas Monitor in normal operation. This chapter also
describes the Beacon 100 in alarm 1, alarm 2, alarm 3, and fail conditions and suggests
response to these conditions. The Instrument Setup program is described at the end of this
chapter.
Normal Operation
Normal operation is defined as follows:
• the start-up procedure is complete.
• the Beacon 100 is not indicating an alarm 1, alarm 2, alarm 3, or fail condition.
• the Beacon 100 is not running the Instrument Setup Program
During normal operation, the Beacon 100 displays the target gas, unit of measure, and
current gas reading sensed at the gas sensor location.
The PILOT light near the display screen should be on during normal operation indicating
that the monitor is receiving incoming power. The output of the analog output terminal
strip is 4 - 20 mA and is proportional to the detection range of the detector head that is
wired to the Beacon 100.
Alarm Indications
This section describes the Beacon 100 in alarm 1, alarm 2, alarm 3, and fail conditions and
suggests response to these conditions. Table 2 lists the alarm indications for each
condition.
NOTE: The Beacon 100 includes alarm on and alarm off delay settings. The alarm
indications described in this section operate according to the default delay
settings.
