FlexZone definitions
Meter:
The meter is the basic unit of measure for FlexZone sensor cable. The
meter is used to define cable segments. The sensitivity profile records the cable
sensitivity for each meter of detecting sensor cable.
Cable segment:
A cable segment is made up of a contiguous group of meters,
and is used for display and control purposes. Cable segments are software-
defined during setup. The cable segment is the finest granularity unit that is
defined by the end-user. Each sensor cable can be divided into up to 50 cable
segments. Cable segments are used to create alarm zones, and therefore, must
begin and end where alarm zone boundaries are required. A single cable
segment, or multiple cable segments, can be assigned to one zone. A cable
segment can have one of the four onboard relays associated with it for alarm
reporting. In addition to the event Threshold that is set for the full length of
detecting cable, an independent Threshold adjustment can be made for each
cable segment. Cable segments can also be defined as inactive, whereby
detecting cable will not report valid targets (by assigning a cable segment to
Zone 0).
Alarm zone:
An alarm zone is made up of one or more cable segments, and is
used for the control and annunciation of sensor alarms (access/secure, graphic
map display with precise target location). There can be up to 60 alarm zones per
FlexZone-60 processor (over two sensor cables) and up to four for a FlexZone-4
processor. Alarm zones are defined in software to match the site-specific zone
layout details (e.g., CCTV coverage, fence sections, gates, buildings, etc.). Any
grouping of segments can be assigned to an alarm zone. The cable segments do
not have to be contiguous, and can come from both sensor cables on one
processor (not two processors). There can be a zone within another zone, and a
zone can bridge inactive cable segments. Zone 0 does not report alarms, and is
used for cable bypasses, and to set detecting cable to inactive (non-detecting).
Zone 0 does not count in the 60, or 4 zone total.
Understanding FlexZone alarm detection
The FlexZone processor constantly evaluates the input signals from the sensor
cables to discriminate between intrusion events and environmental activity. The
characteristic response of a cut event is a sharp spike with a fast rising and fast
falling edge. For a climb event, the response includes the fast rising edge caused
