(1.75 in. to 5 in.). The hardware required for surface-mounting the processor is customer-supplied.
The FlexZone enclosure is hinged and includes a lockable latch (requires a Customer-supplied
pad lock).
Power source and wiring
The FlexZone processor can operate on a wide range of input voltages (12 to 48 VDC). The power
supply, the number of processors, and the lengths of the power cable runs will determine the
gauge of the power cable wiring that is required. In locations where AC power may not be stable or
reliable, an uninterruptable power supply (UPS) should be used for primary power. Assume a
maximum power consumption of 2.5 W per FlexZone processor (with NIC).
Power over the sensor cables
A group of up to five FlexZone processors can share power via the connected sensor cables. In
this case, the central processor is connected to a 48 VDC power supply. The sensor cables from
the central processor are connected to the two adjacent processors (one on each side). The
processor connected to the power supply requires a stable, low resistance earth ground
connection, which also serves as the ground reference for the connected block of processors.
Power and data distribution is setup via the UCM.

processor FlexZone perimeter with power and data over the sensor cables, and redundant Silver
Network communications.
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.

Local and Remote control modes.
