Power Over Sensor Cables - Interlogix FlexZone Series Product Manual

Chapter 3: Calibration and setup

Power over sensor cables

If this processor receives power from a 48 VDC power supply and will distribute
power over the sensor cables to other processors, you must setup the power
distribution scheme via the UCM. If this processor receives power over the
sensor cables, and will provide power to an auxiliary device via the power
connector (T4) you must setup the auxiliary power output function via the Aux
Config tab on the UCM.
The UCM Diagnostics Status field includes three indicators along with voltage
and current readings for Cable A, Cable B and Input/Aux (Auxiliary power output
- Volt readings only). There are also three test checkboxes that are used to test
and verify the selected power distribution function.
Use the test checkboxes on the Status screen to verify the desired function
(Cable A power distribution, Cable B power distribution, Auxiliary power output
via T4).
Note: The Cable Supervision Mode must be set to data supervision before the
test function can be used.

select the test check-box to verify that
the specified function is operational
select the Enable check-box to
select the Power Output check-box to
distribute power via the specified cable side
select data supervision to enable
power distribution over the sensor cable
select the Aux Power Output check-box to
supply 2 W of power via T4
Note: The Aux Power Output voltage is equal to the voltage received over the
sensor cables. Power over the sensor cables and auxiliary output power are
available only when the processor's input voltage is 38 VDC or greater.
1. On the UCM Status tab in the Diagnostic Status field, select the Cable A
checkbox to verify the power distribution function, if this processor will
distribute power over the A side cable.
2. Select the Cable B checkbox to verify the power distribution function, if this
processor will distribute power over the B side cable.
