The XD One uses two LED icons alongside audio sequences to alert and warn users to changing levels
of airborne particulates in operating environments as highlighted below.
If a threshold is breached during operation, the following alarm sequence is used to alert users to act
based on the change in the working environment.
Icon 1 - Short Term Exposure Limit (STEL) Alarm:
The XD One will flash the amber STEL Icon alongside an audible alarm (2 Beeps Per Second).
Icon 2 – Long Term Exposure Limit / Time Weighted Average (TWA) Alarm:
The XD One will flash the red TWA Icon alongside an audible alarm (3 Beeps Per Second).
In the event that both alarms are triggered simultaneously, the TWA alarm will take priority.
Note: The XD One is factory programmed with the following default Short Term Exposure Limit (STEL)
and Long Term Exposure Limit / Time Weighted Average (TWA) alarm warning thresholds.
•
STEL Alarm Warning Threshold – 1000 µm/m3 over 15 minutes
•
TWA Alarm Warning Threshold – 1000 µm/m3 over 8 hours
The default threshold limits have been defined based on a quarter of the permissible limit for most
respirable dusts as outlined in the EH40/2005 guidelines.
Advice outlined in EH40/2005 states that where no specific Short Term Exposure Limit is listed, a figure
three times that of Long Term Exposure Limit should be used. However, always refer to local guidelines
and legislation to ensure that alarm warning thresholds are set at appropriate and permissible values for
the intended operating environment.
