Stopping a Gas Alarm
The low, high, and STEL alarm stops when the ambient gas
level returns to the acceptable range.
The detector computes the TWA value based on an 8-hour
workday. Only deactivating the detector can stop the TWA
alarm.
Acknowledge Latched Alarm
If the latched alarm function is turned on, the audible and
visual alarms continue to sound and flash until the low, high,
or STEL alarm condition is acknowledged. Press C to
deactivate the audible and visual alarms when the current
ambient gas reading falls below the low alarm level. The
alarms cannot be deactivated if an alarm condition is still
present. A TWA alarm condition will not reset.
A STEL alarm may take up to 15 minutes of clean
air readings before the latched alarm can be
deactivated.
