Auxiliary device output power
Processors that are receiving power over the sensor cables can supply up to 2 W
of power to an auxiliary security device through T4, the power connector. The
output power is at the same voltage as the received power input via the sensor
cables. The minimum required voltage to enable power over the sensor cables is
38 VDC. Figure 63 on page 55 illustrates connection diagrams of a FlexZone
processor supplying power and carrying alarm data for an UltraWave microwave
sensor in both Local and Remote control modes.
Power over Ethernet
Silver Network based processors using Ethernet communications have the option
of using Power over Ethernet (Figure 60 on page 51 illustrates an Ethernet based
Silver Network). To use this powering option requires a PoE class 3 switch that is
located within 100 m of the processor, and minimum Category 5 network cable.
Power over Ethernet is supplied to the processor's Network Interface card (NIC)
and the power output on the NIC is connected to the power input on the
processor. Each processor receiving PoE requires an earth ground connection.
Note: It is recommended to use a fully managed PoE switch, to supply power to
a FlexZone processor.
Data over the sensor cables
A group of FlexZone processors can communicate via the connected sensor
cables. In this case, at least one processor requires a network interface card
(NIC) to enable Silver Network communications. The sensor cables from that
processor are connected to the two adjacent processors (one on each side).
Processors that are using the sensor cables for data distribution must be
synchronized to prevent mutual interference.
