2.2.4 RF module BSB AVS71.393
The RF module BSB extends the product range by introducing wireless
communication. The RF module BSB allows system components, such as room
units, to transmit data without laying cables.
In contrast to the RF module AVS71.390 communication occurs between RF
module BSB and basic unit (controller) via BSB. As a result, the RF module BSB
can be placed farther away from the basic unit (controller) (see Technical data).
RF module (AVS71.390) and RF module BSB (AVS71.393)
cannot
be used
concurrently.
l Do not install the unit inside a metal housing.
l Use the device only inside a building.
