extended in order to reduce false (nuisance) alarms.
A learning function will after a learning period adapt an
Alarm algorithm suitable for the smoke and temperature
conditions in the area where the detector is located.
Alarm algorithms for the following areas can be adapted:
Clean area
(higher sensitivity)
Alarm algorithm This is similar to the alarm algorithm for the
.
Pulse up – down counter
The detector have a "pulse up – down counter", starting at "0" and
cannot be negative.
Pulse up – down counter for smoke
When the smoke obscuration S (%/m) > the alarm threshold level, "1"
is added to the counter every second.
When S < the alarm threshold level, "2" is subtracted from the counter
every second.
Pulse up – down counter for temperature
When the temperature T (°C) > the alarm threshold level, "3" is added
to the counter every second)
