System MMI Pack (Room unit and RF receiver)
SMGB0066 rev.0 - 12/2009
note
The RF link between the Room Unit and RF Receiver in system packs is pre-configured at the factory and
-
therefore should be installed at the same site. This makes the installation process fast and easy, but if
products from individual system packs are separated, or mixed with other pre-configured system packs during
installations please refer to the section Binding / Rebinding procedure to bind the desired units together and
allow them to communicate with each other.
4.22.1.2. Installation information
As these products communicate using RF technology special care must be taken during installation. The location of the
RF components as well as the building structure may influence performance of the RF system. To assure system reliability,
please review and apply the information given below.
Within a typical residential building the two products should communicate reliably within a 30m range. It is important to
take into consideration that walls and ceilings will reduce the RF signal. The strength of the RF signal reaching the RF
Receiver depends on the number of walls and ceilings separating it from the Room Unit, as well as the building construction
- the diagram below illustrates an example of typical signal strength reduction. Walls and ceilings reinforced with steel or
plasterboard walls lined with metal foil reduce the RF signal significantly more.
Once a position is selected for the Room Unit this can be checked using the RF Communication Test mode as described in
section Locating the Room Unit. If the position is unsuitable the RF Receiver will not respond and an alternative position for
the Room Unit must be selected.
