The figure above displays a wiring example of one PT2008-A1 being connected to
one matrix. This wiring can only be utilized for PT2008-A1 in standard use cases
and is not permitted in evacuation use cases.
The matrix provides DC 10 V. A fuse (7) protects the internal 10 V power supply. A
short circuit outside of the cabinet has no impact on the whole cabinet.
The 10 V power supply, the 4 logic signals and the audio signal are connected to
the call station interface of PT2008-A1.
The PT2008-A1 call station interface provides a RJ45 connector with all the signals,
which facilitates the wiring of the PT2008-A1.
Standard copper Ethernet cables (CAT5) with RJ45 connectors are used for the
wiring (8), connecting the call station interface of PT2008-A1 to the call station
PT2008-A1.
