Responding to Alarms
This section describes response to gas, over range, battery, sensor failure, clock failure, and
system failure alarms.
Responding to Gas Alarms
1 . Determine which gas alarm has been activated.
2 . Follow your established procedure for an increasing gas condition or a decreasing
oxygen condition.
3 . Reset the alarm as necessary or allowed.
a. If LATCHING is set to ON (factory setting) in Maintenance Mode, the gas reading
must fall below (or rise above for an oxygen low alarm) an alarm setting before you
can reset the alarm condition using POWER MODE or AIR.
b. If LATCHING is set to OFF in Maintenance Mode, the alarm condition will
automatically reset when gas reading falls below (or rises above for an oxygen low
alarm) an alarm setpoint.
Responding to an H2 RICH Alarm (H
2
-Compensated CO Sensor Only)
The H2 RICH alarm automatically clears once the hydrogen level decreases below 2000 ppm
(parts per million).
Responding to Over Range Alarms
WARNING: An over range condition may indicate an extreme combustible gas, toxic
gas, or oxygen concentration. Confirm the gas concentration with a
different GX-3R or with another gas detecting device.
CAUTION: High off-scale readings may indicate an explosive concentration.
PRUDENCE: Des lectures élevées hors échelle peuvent indiquer une concentration
explosive.
1 . Determine which channel is in alarm.
2 . Follow your established procedure for an extreme gas condition.
3 . If LATCHING is set to ON (factory setting) in Maintenance Mode, reset the alarm
using POWER MODE or AIR once the alarm condition clears.
