The operating range of such add-ons depends on the maximum
power of the U
pn
interface of the communications system, and
on the power consumption of the respective equipment. The
range can be increased by the deployment of secondary AC
adapters. For the relevant technical details and a complete over-
view of the various equipment combinations that you can con-
figure, please refer to the chapter entitled “Accessories and
Adapters“ in the “Mounting and Commissioning“ user guide.
Please also refer to the information on the scope of available
features in expanded equipment combinations.
Note:
Secondary devices are activated by the communications
system. The communications system detects whenever there
are two adapters of the same typeon a T-Comfort 830 Sys-
temtelefon. This is not permitted, and for this reason, they
are not released for operation.
