4.5.1. Sensitivity classes according to EN 54 Part 5

The MAGIC.SENS T 400 E LSN gives you the opportunity, according to the

programming, to specify one of the six sensitivity classes listed above.

In the sensitivity classes A1, A2S and BS, the MAGIC.SENS T 400 E LSN is operated

as a pure thermo --maximum detector.

Here in the class A2S the detector does not activate under 54_C and in class BS not

under 69_C.

The sensitivity classes A2S and BS are therefore especially suitable for applications

where over a longer period, higher temperature r ates--of--rise occur, e.g. in kitchens

or boiler rooms.

The sensitivity classes A1R, A2R and BR mean that in addition to the thermomax

unit, the thermodifferential unit is also active.

These sensitivity classes are especially well--suited for use in unheated buildings where

the ambient temperature can vary greatly but temperature rates--of--rise do not last long.

With the thermodifferential unit, the detectors in classes A1R/A2R activate at

T< 54°C and in class BR at T< 69°C; see table page 15.

The selection of the sensitivity class also depends on the installation height of the

detector (see table above).

For the highest security against false alarms, with room heights below 6 m, the classes

A1 and A1R should not be selected, although this is allowed in principle. F urthermore,

the expected application temperature m ust be taken into consideration.
