If set as N. DE-EN, the alarm 1 relay is de-energized in normal operation and
energizes when an alarm 1 condition is initiated.
If set as N. EN, the alarm 1 relay is energized in normal operation and de-ener-
gizes when an alarm 1 condition is initiated.
If set as LATCH, you must press the ENTER button to reset the alarm 1 circuit
after the alarm 1 condition passes.
If set as SELF-RST, the M2A automatically resets the alarm 1 circuit after the
alarm 1 condition passes.
The amount of time the M2A delays activation of the alarm 1 circuit once an
alarm 1 condition is initiated. It can be set in 1 second increments from 0 - 60
seconds, in 1 minute increments from 1 - 15 minutes, and in 15 minute incre-
ments from 15 - 60 minutes.
The amount of time the M2A delays turning off the alarm 1 circuit once an alarm
1 condition passes. This parameter appears only if the alarm 1 relay reset setting
is set to SELF-RST. It can be set in 1 second increments from 0 - 60 seconds, in
1 minute increments from 1 - 15 minutes, and in 15 minute increments from 15 -
60 minutes.
The gas reading at which the M2A initiates an alarm 2 condition.
Indicates if the alarm 2 circuit is activated by gas readings increasing (Increase)
or decreasing (Decrease) to the ALARM-1 Level.
If set as N. DE-EN, the alarm 2 relay is de-energized in normal operation and
energizes when an alarm 2 condition is initiated.
If set as N. EN, the alarm 2 relay is energized in normal operation and de-ener-
gizes when an alarm 2 condition is initiated.
If set as LATCH, you must press the ENTER button to reset the alarm 2 circuit
after the alarm 2 condition passes.
If set as SELF-RST, the M2A automatically resets the alarm 2 circuit after the
alarm 2 condition passes.
The amount of time the M2A delays activation of the alarm 2 circuit once an
alarm 2 condition is initiated. It can be set in 1 second increments from 0 - 60
seconds, in 1 minute increments from 1 - 15 minutes, and in 15 minute incre-
ments from 15 - 60 minutes.
The amount of time the M2A delays turning off the alarm 2 circuit once an alarm
2 condition passes. This parameter appears only if the alarm 2 relay reset setting
is set to SELF-RST. It can be set in 1 second increments from 0 - 60 seconds, in
1 minute increments from 1 - 15 minutes, and in 15 minute increments from 15 -
60 minutes.
The zero suppression feature helps prevent "jumpy" readings near the fresh air
reading.
For example, if the zero suppression setting is 2.0% LEL, the M2A will display
a reading of 0% LEL for gas readings from -2% LEL to 2% LEL. It is settable
from 0 to 6% of the detection range.
