The figure above displays two examples of open circuit redundant external wiring of multiple PT2009-A1 being connected to one cabinet. This wiring can only be utilized in standard use cases and is not permitted in evacuation use cases.
An open circuit to one connected PT2009-A1 affects just this PT2009-A1. The other PT2009-A1 still work properly.
The three connected PT2009-A1 share one analog audio input channel. Therefore, only one PT2009-A1 can be active at the same time.
A short circuit in RS485 or analog audio external wiring (9) between the PTO2008-A1 (6) and the PT2009-A1 (2) affects all 3 connected PT2009-A1.
A short circuit in 24 V external wiring (9) affects only the connected PT2009-A1.
Variant A
PCA2011-A1 and PCA2018-A1 (3) provide isolated DC 24 V.
A short circuit outside of the cabinet has no impact on the signals in the cabinet.
The PCA2001-A1 (4) detects a ground fault on the 24 V wiring to PT2009-A1.
The PNA2009-A1 (5) provides an isolated 'PACE-Bus' (RS485). A short circuit outside of the cabinet has no impact on the communication in the cabinet.
The 24 V power supply, the 'PACE-Bus' (RS485) and the analog 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 an RJ45 connector for all the signals, facilitating the wiring of the PT2009-A1.
Standard copper Ethernet cables (CAT5) with RJ45 connectors are used for the wiring (8), connecting one PTO2008-A1 to the next, and the wiring (9), connecting PTO2008-A1 to PT2009-A1.
Variant B
The PN1002-A1 and PN2009-A1 (10) provide an isolated DC 24 V with the ground fault monitoring, an isolated 'PACE-Bus' (RS485) and the isolated analog audio input and analog audio output.
A short circuit outside of the cabinet has no impact on the signals in the cabinet.
The 24 V power supply, the 'PACE-Bus' (RS485) and the analog 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 an RJ45 connector for all the signals, facilitating the wiring of the PT2009-A1.
Standard copper Ethernet cables (CAT5) with RJ45 connectors are used for the wiring (8), connecting one PTO2008-A1 to the next, and the wiring (9), connecting PTO2008-A1 to PT2009-A1.
