13.4.2 Alarm
WARNING
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 indoor units 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.
Each indoor unit 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 Each indoor unit must be connected to a separate remote
controller. In case indoor units are operating under group
control, it is possible to only use one remote controller per
room.
3 The remote controller put in the room served by the indoor unit
must be in 'fully functional' or 'alarm only' mode. In case the
indoor unit is serving a different room than where it is installed,
a remote controller is required in both installed and served
room. For details about the different remote controller modes
and how to set up, please check the note below or refer to the
installation and operation manual delivered with the remote
controller.
4 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 the SV unit, or to the
optional output PCB of the indoor unit of that specific room. The
outdoor SVS will trigger for any R32 leak detected in the complete
system. For SV units and indoor units, SVS is only triggered when
its own R32 sensor detects a leak. For more information on the
SVS output signal, see "17.9 To connect the external
outputs"[443].
▪ 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. This controller can
be master or slave.
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. This controller can
be master or slave.
Supervisor The controller only acts as leak detection
alarm (for the whole system, i.e. multiple
indoor units and their respective controllers).
No other functionality is available. The remote
controller should be placed at a supervised
location. This remote controller can only
be the slave.
Note: In order to add a supervisor remote
controller to the system, a field setting must
be set on remote controller and outdoor unit.
Indoor units and SV units need 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.
Examples
1 In case of one R32 safety system compatible remote controller,
it should be the master and in the same room of the indoor unit.
