To change the factory-set alarm setpoints, refer to the section

“Calibration and Setting Alarm Setpoints.”

You can disable an alarm by setting the alarm setpoint to 0.

Setting the Low Alarm setpoint to 0 turns off the Low and

TWA Alarms.

The detector allows you to set the O

alarm setpoints for Low

Alarm above or below 20.9% and to set High Alarm above or

below 20.9% as desired.

Stopping a Gas Alarm

The Low and High Alarms stop when the ambient gas level

returns to the acceptable range.

Note

If alarms are set to latch, press to reset the

audible and visual alarms.

The detector computes the TWA value based on an 8-hour

workday. Only deactivating the detector can stop the TWA

Alarm.
