Installing the FlexZone processor

Power over Ethernet
For power over Ethernet, a class 3 PoE switch is required. In this configuration, minimum Category
5 cable is required and the maximum distance between the FlexZone processor and the PoE
switch is 100 m (328 ft.). Each processor receiving PoE requires an earth ground connection.
Auxiliary device power output
Processors that are receiving power via the sensor cables can be setup (via the UCM) to supply
power (2 W) to an auxiliary device. In this case the power connector T4 is used to make the
auxiliary device power connection. The output voltage at T4 is equal to the input voltage over the
sensor cables. The auxiliary device can communicate its alarm status through the FlexZone
processor’s Aux inputs (in Remote control mode).
Senstar’s UltraWave microwave sensor can receive power from a FlexZone processor, as well as
communicate alarm status via the Silver Network or through the FlexZone processor’s Aux inputs.
The recommended method is via the Silver Network which requires network interface cards on
both the FlexZone processor and the UltraWave receiver. Figure 76:
illustrates connection
diagrams for the UltraWave microwave sensor in both Local and Remote control modes. Contact
Senstar Customer Service for additional details.
Backup power
Senstar recommends that the FlexZone sensor system be powered from an uninterruptible power
supply (UPS). Connect AC mains to the UPS and the UPS to the DC power source. In this way, if
AC power is interrupted, the FlexZone sensor system can operate on battery power while AC
power is being restored.
CAUTION The PoE NIC is intended to supply power only to the processor on
which it is mounted. Do not attempt to power an auxiliary device with
the PoE NIC.
