*HH percent will indicate whichever of Temperature, Rate of Rise, or Smoke/CO has been highest, in terms of the percentage of its alarm threshold. It will be rounded to the nearest 5%, and the last digit will indicate which type it represents. A last digit of 0 or 5 indicates smoke or CO. A last digit of 1 or 6 indicates temperature, and a last digit of 2 or 7 indicates temperature rate of rise.

For example, 51 will indicate that temperature has been highest at 48-52% of the alarm threshold. 65 will indicate smoke/CO has been highest, at 63-67% of the alarm threshold.

For temperature 20°C will be 0% and the alarm limit 100%.

All History High and History Low values (where used as maximum and minimum) will be based on Step Limited values i.e. the same values as are used for alarm comparison. However note that PreAlarm comparisons are performed using “CV”, i.e. values without Step Limited filtering. Therefore a PreAlarm may occur even though the “History High” value is less than the PreAlarm Threshold.
