The figure above displays a wiring example of one PT2003-A1 being connected to
one matrix. This wiring can be utilized for PT2003-A1 in evacuation use cases.
PCA2011-A1 and PCA2018-A1 (3) provide isolated DC 24 V. A short circuit
outside of the cabinet has no impact on the whole cabinet.
The PCA2001-A1 (4) detects a ground fault on the 24 V wiring to PT2003-A1.
The PNA2009-A1 (5) provides an isolated 'PACE-Bus' (RS485). No other
components are allowed on 'PACE-Bus' (RS485) together with PT2003-A1. The
PT2003-A1 is connected with one PNA2009-A1. A short circuit outside of the
cabinet has no impact on the 'PACE-Bus' communication to the other 'PACE-Bus'
components.
The 24 V power supply, the 'PACE-Bus' (RS485) and the audio signal are
connected to PTO2008-A1 (6).
A fuse on the PTO2008-A1 protects the internal 24 V power supply.
The PTO2008-A1 provides a RJ45 connector with all the signals, which facilitates
the wiring of the PT2003-A1.
Standard copper Ethernet cables (CAT5) with RJ45 connectors are used for the
wiring (8), connecting between PTO2008-A1 and PT2003-A1.
