Notice!
Depending on the number of air sampling openings, fire sensitivity classes A, B and C can all
be achieved with the detection modules available.
The table shows the sensitivities you can choose from
Response sensitivity (main alarm)
DM-TP-50(80) Detector

Not permissible
Not permissible
1.0%/m (1.6%/m) light

Notice!
The sensitivity value is based on measurements with standard test fires (old value in
brackets).

Planning Limits

The following limit values must always be observed for the FCS-320 series:
Limiting values
The maximum monitoring area of an air sampling opening corresponds to the monitoring area
of point-type detectors in accordance with the applicable planning guidelines.

Operation Guide
Aspirating Smoke Detector
Application example
Very early detection: significant smoke
dilution through air conditioning in IT
areas
Early detection: significant time gains
thanks to very early fire detection
(without air condition)
Normal detection: fire detection with the
advantages of smoke aspiration systems
