Verifying the luminaire segment boundaries

5. On the UCM, verify that the alarm was reported by the luminaire defined as the second
segment’s start boundary.
6. Move along and continue tapping fence posts to mark the start points of the designated
segment boundaries.
Setting the Threshold
The Threshold represents the received signal strength at which the Event Count is incremented.
An independent Threshold can be set for each of the defined segments. Thresholds can be
adjusted for any high risk or low threat areas, as well as any areas that may be subject to a higher
NAR such as an open stretch of fence that is regularly exposed to strong winds. The Threshold
can also be used to disable alarm detection in a segment by setting the Threshold to the maximum
value of 255. Reducing the Threshold in high risk areas will increase the Pd in that area. However,
a lower Threshold setting may increase the nuisance alarm rate. For an area where the threat is
considered low, increasing the Threshold will reduce the chance of nuisance alarms occurring
while still providing an acceptable Pd.

Note
Senstar recommends marking a site plan (or a table) with numbered
luminaire locations, the segments to which the luminaires are assigned
and the alarm zones to which the luminaire segments are assigned.
The initial segment begins with luminaire 1 (by default).
