Alarm Logic/Resetting Alarms
The gas alarm logic can be set to either latching or self resetting with the
GX-2009 Setup Program by setting the Alarm Pattern parameter. See the
GX-2009 Setup Program Operator’s Manual for information on how to set
the alarm logic. If Alarm Pattern is set to Latch, the gas alarms are
latching. If Alarm Pattern is set to Reset, the gas alarms are self-resetting.
The standard factory setting is Latch for latching alarms.
If the alarms are latching, then an alarm indication will continue even if the
gas reading causing the alarm decreases below the alarm setpoint
(increases above for oxygen Warning) and will continue until the alarm is
reset. To be able to reset the alarm, the gas reading that caused the alarm
must decrease below the alarm setpoint (increase above for oxygen
Warning) before that alarm can be reset. To reset latching alarms, press
and release the POWER MODE button after the gas reading falls below the
