Advanced mode

The latest generation of detectors are the following:
 Conventional photoelectric smoke detector 4452
 Analog photoelectric smoke detector 4401
 Analog multi detector 4400
NOTE! NOTE! NOTE! NOTE! NOTE! NOTE! NOTE!
The analog detectors 4401 and 4400 can via the address setting tool
4414 be set in different modes. In this chapter is only the Advanced
mode described. The detectors are factory set to the NORMAL
mode, see chapters "COM loop units", page 32 and "Functions /
Services / Features", page 93. The analog detectors 4401 and 4400 in
NORMAL mode will function as and replace the analog detectors
4301 and 4300 in NORMAL mode respectively.
detectors 4301 and 4300 cannot use the Advanced mode.)
The Advanced mode can be set with the address setting tool 4414
only. Not with the address setting tool 3314.
The conventional detector 4452 uses some of the advanced mode
functions, see the function respectively below in this chapter.
Artificial Intelligence (AI function) uses combined smoke and heat
sensing for the fire judgement, as well as variable sensitivity and time
delay based on the smoke and temperature changes just before the
alarm level is reached. This will secure the real fire alarms and reduce
the not wanted false (nuisance) alarms with up to 46 %.
The AI function is depending on if the detector is a photoelectric
smoke detector (4452 / 4401) or a multi detector (4400):
Combined heat and smoke sensing will guarantee reliable and
accurate fire alarm detection, e.g. by shortening the delay time
and/or raise the sensitivity (i.e. lower the alarm threshold level).
Variable delay time. The delay time is influenced by the
temporary temperature and/or smoke obscuration changes just
before and after the alarm threshold level was passed. The
delay time before a fire alarm is activated can be shortened up
to 50 % (e.g. from 20 to 10 sec.), or the delay time can be
