X95 - Aritech Series 950
TestVal: The value returned during Device Self-Test. A value that is less
than the alarm threshold will result in a maintenance condition.
FldAvg: The average value of the device measured over a 20-minute
period.
Obsc: % Obscuration (Smoke Detectors):
Temp: Temperature °C (Heat Detectors): An estimate of the smoke
obscuration expressed as %/meter or the heat °C. This is
calculated from the value returned by the device and is given for
information purposes only. The fire panel uses the value for
alarm and fault determination.
Alarms: The number of fire alarms produced by the device since the last
clear statistics operation.
High: The highest value achieved by the device and the date (dd/mm)
and time (hh:mm) that this occurred.
Low: The lowest value achieved by the device and the date (dd/mm)
and time (hh:mm) that this occurred.
Contam: Contamination: The amount of contamination is calculated from
the long-term drift of the detector, and indicates the cleanliness
of the detector. The long-term drift is generally caused by
contamination, but is also affected by day/night effects
especially where a zone is occupied during the day and empty
at night. *See Day Level, Page 81.
