13.1.4 Safety measures
No safety measure
When the room area is sufficiently large, no safety measures are
required. This also includes an indoor unit installed in the lowest
underground floor.
Therefore the R32 safety system in the indoor unit in a sufficiently
large room can be deactivated (active by default) by changing the
setting in the user interface as shown below:

Alarm
WARNING
ü Do NOT use 'Alarm' as the ONLY safety measure in
case the indoor unit is installed in an occupied space
where people are restricted in their movement.
▪ Combine or use another safety measure.
R32 safety system compatible remote controllers (e.g. BRC1H52/82*
or later type) used with the air curtain have a built-in alarm as a
safety measure. For installation of the remote controller, please refer
to the installation and operation manual delivered with the remote
controller.
The compatible air curtain must be connected with a R32 safety
system compatible remote controller (e.g. BRC1H52/82* or later
type). These remote controllers have implemented safety measures
that will warn the user visually and audibly in case of a leak.
For installation of the remote controller, it is mandatory to follow the
requirements.
1 Only a safety system compatible remote controller can be used.
See technical data sheet for remote controller compatibility (e.g.
BRC1H52/82*).
2 The remote controller put in the room served by the air curtain
must be in 'fully functional' or 'alarm only' mode. For details
about the different remote controller modes and how to set up,
please refer to the installation and operation manual delivered
with the remote controller.
3 For buildings where sleeping facilities are offered (e.g. hotel),
where persons are restricted in their movements (e.g.
hospitals), an uncontrolled number of persons is present or
buildings where people are not aware of the safety precautions
it is mandatory to install one of the following devices at a
location with 24-hour monitoring:
▪ a supervisor remote controller
▪ or a centralised controller. E.g., iTM with external alarm via
WAGO module, iTM with built-in alarm, …
Note: The remote controllers with built-in alarm will generate a
visible and audible warning. E.g. the BRC1H52/82* remote
controllers can generate an alarm of 65 dB (sound pressure,
measured at 1m distance of the alarm). Sound data is available in
the technical data sheet of the remote controller. The alarm should
always be 15dB louder than the background noise of the room.
A field supply external alarm with a sound output 15dB louder than
the background noise of the room MUST be installed in the following
cases:
▪ The sound output of the remote controller is not sufficient to
guarantee the 15dB difference. This alarm can be connected to
the SVS output channel of the outdoor unit, or to the optional
output of the air curtain, if available. The outdoor SVS will trigger
when a R32 leak is detected. For more information on the SVS
output signal, see "17.5To connect the external outputs"[435].
▪ A centralised controller without built-in alarm is used, or the sound
output of the centralised controller with built-in alarm is not
sufficient to guarantee the 15 dB difference. Please refer to the
installation manual of the centralised controller for the correct
procedure to install the external alarm.
Note: Depending on configuration, the remote controller is operable
in three possible modes. Each mode offers different controller
functionality. For detailed information about setting the operation
mode of the remote controller and its function, please refer to the
installer and user reference guide of the remote controller.
Mode Function
Fully functional The controller is fully functional. All normal
functionality is available.
Alarm only The controller only acts as leak detection
alarm (for a single indoor unit). No
functionality is available. The remote
controller should always be put in the same
room as the indoor unit.
Supervisor The controller only acts as leak detection
alarm. No other functionality is available. The
remote controller should be placed at a
supervised location.
Note: In order to add a supervisor remote
controller to the system, a field setting must
be set on remote controller and outdoor unit.
The air curtain needs to be assigned an
address number.
Note: Incorrect use of remote controllers can result in occurrence of
error codes, non-operating system or system that is not compliant to
applicable legislation.
Note: Some centralised controllers can also be used as supervisor
remote controller. For further details on installation, please refer to
the installation manual of the centralised controllers.
