15.4 Combining units and options
INFORMATION
Certain options may NOT be available in your country.
15.4.1 Possible options for the indoor unit
Make sure you have the following mandatory options:
▪
User interface: Only a safety system compatible user interface can be used. See
the technical data sheet for user interface compatibility (e.g. BRC1H52*)
Note:
The user interface will generate a visible and audible warning in case of
refrigerant leakage detection. E.g., BRC1H52* user interfaces can generate an
alarm of 65 dB (sound pressure, measured at a distance of 1 m from the alarm).
Sound data is available in the technical data sheet of the user interface. The alarm
should always be 15 dB louder than the background noise of the room. In case of
higher background noise we recommend connecting an external alarm (field
supply) to the optional output PCB of the indoor unit. This field supplied alarm
must be mounted in every room where an indoor unit is installed.
CAUTION
▪
Each indoor unit has to be connected to a separate user interface. Only a safety
system compatible remote controller can be used as the user interface. See
technical data sheet for remote controller compatibility (e.g. BRC1H52/82*).
▪
The user interface has to be put in the same room as the indoor unit. For details,
please refer to the installation and operation manual of the user interface.
