1. 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
2.2.3 Locating the Room Unit
on page 6. If the position is unsuitable the
RF Receiver
will not respond and an alternative position for the
Room Unit
must be selected.
