Explanation of the Sensor Values
Momentary
: Momentary value in this menu will be updated following every detector
polling, i.e. approx. every 6 second.
Weekly in NORMAL mode:
The very first week average sensor value for a new installed
detector type 430x and 440x in NORMAL mode is calculated within 2½ minutes after SSD
download & restart. During these 2½ minutes, no fire alarm can be activated and "Weekly:
00.0%/m" will be shown. The "Weekly" value will thereafter be updated every week.
Weekly in Advanced mode
: For the 440x detectors in Advanced mode, the "Weekly"
value is 00.0%/m on delivery. It will be updated during the first 13 minutes when the
detector has been installed. It will thereafter be calculated every 13th minute but will then
only be changed downwards if required. After 18 hours it can be changed downwards or
upwards and after additional 18 hours (36 hours in all) it can be changed downwards or
upwards and it is also saved in the detector's EEPROM, i.e. that value will be used after
the detector loses power. The "Weekly" value for the 440x detectors in Advanced mode is
also called the "Contamination Compensation Value (CCV).
Performance Factor
: The "Performance factor" and "Min. / Max." values are updated each
night (00:00), i.e. the values shown are from the previous day. For more information on
performance factor, see the Planning instructions for the system.
The Performance factor can be 0.00 – 2.55. How the Performance factor (PF) is calculated
is shown to the left.
In an "unstable" environment the Performance factor will be higher than 0.00. This could
for example be the case in a factory (e.g. "dirty" activities during working hours – no or
clean activities during the night) and is not a problem as long as there are no nuisance
(false) alarms or other problems.
