Bosch FCS-320-TP2 - Planning Limits

38 en | Planning Aspirating Smoke Detector
2018.04 | 2.0 | F.01U.130.926 Operation Guide Bosch Sicherheitssysteme GmbH
Class Description Application example
A Aspirating smoke detector with
extremely high sensitivity
Very early detection: significant smoke
dilution through air conditioning in IT
areas
B Aspirating smoke detector with
increased sensitivity
Early detection: significant time gains
thanks to very early fire detection
(without air condition)
C Smoke aspiration system with normal
sensitivity
Normal detection: fire detection with the
advantages of smoke aspiration systems
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

4.5 Planning Limits
The following limit values must always be observed for the FCS-320 series:
Limiting values Maximum number of air sampling openings per detector
module
32
Maximum total pipe length 300m (2 x
280m)
Minimum pipe length between 2 air sampling openings 4m
Minimum pipe length between 2 air sampling openings 12m
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.
