Alarms
This section covers alarm indications, including multiple alarms and trouble
alarms. It also tells you how to respond to an alarm condition.
NOTE: False alarms may be caused by radio frequency (RF) or
electromagnetic (EMI) interference. Keep the GX-2001 away from
RF and EMI sources such as radio transmitters or large motors.
Alarm Indications
The Model GX-2001 will sound an alarm and the unit will vibrate when one
of the target gas concentrations rises above the first alarm point, or in the
case of oxygen, falls below the low point alarm setting for that gas.
The Model GX-2001 also sounds an alarm and vibrates when the second
alarm point is reached for HC, CO, and H
2
S, when the concentration of
oxygen rises above 23.5% in the monitoring area, and when the STEL
alarm points are reached for CO and H
2
S.
When a trouble condition occurs, such as a sensor failure or low battery
charge, the unit will also sound an alarm but it will not vibrate.
The table below summarizes the types of alarms produced by the Model
GX-2001.
