5.3.2 DYFI
3D
- Dynamic Filtering
The AutroGuard® Multicriteria Protector utilizes DYFI
3D
Dynamic
Filtering. Together with the DYFI
3D
Particle/Smoke Signature Analysis
and advanced algorithms, the protector distinguishes accurately
between real fires and nuisance alarm sources, thus minimizing
potensial false alarms. The dynamic filtering is always active.
Each protector has three different filter functions:
The smouldering fire filter provides accurate and
quick detection in the event of a smouldering fire,
i.e. in a situation where a potential fire with no
flames develops during a longer period.
The transient filter virtually eliminates false
alarms caused by phenomena that are not related
to a real fire. Such phenomena can be short
pulses caused by, for example, vapour, cigarette
smoke etc.
The pollution filter maintains the chosen
sensitivity throughout the protector’s entire
lifetime, even with a polluted protector.
