•
segment - A segment can be made up of a single head or a contiguous group of heads
(numerically sequential). Segments are software-defined during setup, and are assigned to
zones for display and control purposes. Each Senstar LM100 system can be comprised of up
to 50 segments. A single segment, or multiple segments, can be assigned to one zone. A
segment can have a relay associated with it for alarm reporting. Each luminaire segment has
an independent event threshold. Segments can also be defined as inactive (no alarm
detection) by setting the threshold to the maximum value of 255.

•
zone - A zone is made up of one or more segments, and is used for the control and
annunciation of sensor alarms (graphic map display with target location to the nearest head).
There can be up to 50 alarm zones per Senstar LM100 system. Zones are defined in software
to match the site-specific zone layout details (e.g., scheduled luminaire activation, CCTV
coverage, fence sections, gates, buildings, etc.). Any grouping of segments can be assigned
to a zone. The segments do not have to be contiguous, and can come from any combination
of heads.

Senstar LM100 alarm detection
The luminaires provide the detection for the Senstar LM100 system by evaluating the minute
vibrations from the fence to determine whether a disturbance is a valid intrusion or environmental
activity. The characteristic signal response of a cut event is a sharp spike with a fast rising edge
and fast falling edge. For a climb event, the response includes the fast rising edge caused by the
initial contact with the fence, which is followed by a series of peaks and valleys resulting from the
continued presence and changing stresses on the fence. Environmental activity is generally of
longer duration, lower magnitude, and has more gradual increases and decreases. Each luminaire
analyzes the fence disturbance signals from the section of fence it monitors to determine a valid
alarm condition. The luminaires communicate over the wireless mesh network and pass the alarm
data to the gateway via the luminaire AP. The gateway records and reports the alarm. The
gateway can record and report multiple disturbances simultaneously for the full length of the
protected fence.

When the received signal exceeds the Threshold setting, the Event Count is incremented.

The next Event will not be recorded until the period specified by the Event Window has lapsed.

Once the Event Window has lapsed, the next time the received signal exceeds the Threshold,
