View System Information Menu
The View System Information Menu consists of only one display screen
which indicates the version number of the firmware that is running the
instrument and the system voltage. The system voltage is the voltage that
is directly running the instrument’s circuitry.
ALARM-2 OFF DELAY
(0 sec)
The amount of time the Beacon 200 delays turning off the alarm 2 circuit
once an alarm 2 condition passes.
ALARM-2 (activation)
(INCREASING)
Indicates if the alarm 2 circuit is activated by gas readings
INCREASING
or
DECREASING
to the ALARM-2 Level.
ALARM-2 Relay (action)
(NORMALLY DE-ENERGIZED)
If set as
NORMALLY DE-ENERGIZED
, the channel’s alarm 2 relay is de-
energized in normal operation and energizes when an alarm 2 condition
is initiated.
If set as
NORMALLY ENERGIZED
, the channel’s alarm 2 relay is
energized in normal operation and de-energizes when an alarm 2
condition is initiated.
ALARM-2 Relay (reset)
(LATCHING)
If set as
LATCHING
, you must press the RESET button to reset the
alarm 2 circuit after the alarm 2 condition passes.
If set as
SELF RESETTING
, the Beacon 200 automatically resets the
alarm 2 circuit after the alarm 2 condition passes.
NOISE FILTER
(3)
The noise filter feature helps “smooth out” jumpy or noisy signals from
the detector head. You can set the noise filter from 1 to 8.
A setting of
8
produces the greatest amount of smoothing but also
responds slowest to changes in the response reading.
A setting of
1
responds fastest to changes in the response reading but
produces the least amount of smoothing.
ZERO SUPPRESSION
(2% of full scale)
The zero suppression feature helps prevent “jumpy” readings near the
fresh air reading.
For example, if the zero suppression setting on the H
2
S channel is
2% of
full scale
, the Beacon 200 will display a reading of 0 ppm for gas
readings from -2 ppm to 2 ppm.
