Processor Location Guidelines - Interlogix FlexZone Series Product Manual

Processor location guidelines

The FlexZone processor can be mounted outdoors on a post, either on, or
separate from, the fence on which the sensor cables are installed (see Figure 9).
A rigid fixed post is recommended for outdoor applications. The FlexZone
processor can also be installed indoors or outdoors on a flat stable surface. Post-
mount hardware is supplied for post sizes from 4.5 cm to 12.7 cm. 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 distribution 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 power supply requires a
stable, low resistance earth ground connection, which also serves as the ground
reference for the block of five FlexZone processors. Power and data distribution
is setup via the UCM. Figure 10 illustrates a 7.2 km (4.5 mi.) 12 processor
FlexZone perimeter with power and data over the sensor cables, and redundant
Silver Network communications.
