Sensor mode 1 'Heat detector'
Description
This sensor mode is especially suited for applications where the detector should
only react thermally.
The heat detector FDOOT271 has the following parameter sets:
A1R (1)
l
A1S (3)
l
Notes on A1 designations
A1 parameter sets should be operated at a room temperature of around 25 °C.
l
However, they can be applied at temperatures up to 50 °C. The static response
temperature is 60 °C.
Notes on the designations R and S
Compared with S parameter sets, R parameter sets also trigger an alarm when the
temperature increases (e.g. from 20 °C to 50 °C within a few minutes).

temperature increase of < 10 K/min, this value rises by a few degrees.
This parameter set meets the criteria of standard EN 54-5.
