3.11 Working with the Gas Alarm
3.11.1 Gas-Alarm Light
If the detected gas level reaches the gas-alarm level as set by the ALRMLVL function, the front panel
ALARM (red) light will flash and the audible alarm, if activated (refer to AUDALRM function on page
16), will start beeping. The ALARM light and audible alarm will automatically turn OFF once the
detected gas level drops below the gas-alarm level.
3.11.2 Silencing a Gas Alarm
Pressing the SILENCE button while the alarm circuit is activated causes the audible alarm to turn OFF
for a period of time as set by the SILENCE function (page 17). The front panel ALARM light will continue
to flash as an indication that an alarm condition still exists. At the end of the silence period if the detected
gas level is still above the gas-alarm level the audible alarm will reactivate.
3.12 Clearing the PPM and Faults Data
Up to 200 gas measurements and 30 fault events are stored by the monitor.

long tone should be heard when the data has been successfully cleared.
