Connect PT2009-A1 via copper Ethernet cable (CAT5) with PN2001-A1 or PN2009-A1.
1 | Cerberus PACE Compact cabinet |
2 | External 'Desk call station (RS485, 8+1)' PT2009-A1 with accessories |
3 | 'RS485 module (1 port)' PN1002-A1 or 'RS485 module (1 port, DIN rail)' PN2009-A1 |
4 | Wiring to PN2009-A1 |
5 | Copper Ethernet cable (CAT5) with RJ45 connector, connecting PN2009-A1 to the first PT2009-A1 |
6 | Copper Ethernet cable (CAT5) with RJ45 connector, connecting one PT2009-A1 to the next |
The figure above displays an example of daisy chain 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.
Any fault in the wiring between the PN2001-A1 or PN2009-A1 (3) and the first PT2009-A1 (2) affects all three connected PT2009-A1.
The three connected PT2009-A1 share one analog audio input channel. Therefore, only one PT2009-A1 can be active at the same time.
The PN2001-A1 and PN2009-A1 (3) provide an isolated DC 24 V with ground fault monitoring, an isolated 'PACE-Bus' (RS485), and 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 PN2001-A1 and PN2009-A1 provide 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 (5), connecting PN2001-A1 or PN2009-A1 to the first PT2009-A1, and the wiring (6), connecting one PT2009-A1 to the next.
