Cyber sensor functions

The latest generation of detectors are the "Cyber sensors".
The Cyber sensor "family" consists of the following detectors:
 Conventional photoelectric smoke detector 4352
 Conventional multi detector 4350
 Analog photoelectric smoke detector 4301
 Analog multi detector 4300
NOTE! NOTE! NOTE! NOTE! NOTE! NOTE! NOTE!
The analog detectors 4301 and 4300 can via the address setting tool
3314 be set in different modes but in EBL128 can only NORMAL
mode be used.
The detector functions are described in chapters
"COM loop units", page 30 and "Functions / Services / Features",
page 81.
The conventional detectors 4352 and 4350 uses some of the cyber
sensor functions. See the function respectively below.

The AI function
is used to secure the real fire alarms but also to
reduce the false (nuisance) alarms with up to 46 %. The AI function
is depending on if the detector is a photoelectric smoke detector only
or a multi (smoke and heat) detector:
Combined heat and smoke sensing will guarantee reliable and
accurate fire alarm detection, e.g. by shortening the delay time
and/or adjust the sensitivity (lower 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
extended in order to reduce false (nuisance) alarms.
