methods above. The stronger the pull the more the alarm will be pulled towards the SE
receiver, with "Linear" having no extra pull. Verify the surrounding areas to make sure
they have not been adversely affected.
The five different location algorithms can individually limit how close other SE receivers
must be to the level of the SE receiver hearing the alarm the best, before they will be
included in the alarm. "Classic" (original Security Escort algorithm), "Linear", "Low" pull,
"Medium" pull and "Strong" pull each have a separate setting. By adjusting this setting
you can control if distant SE receivers with low receive levels will be considered in the
alarm calculation.
You can add "Virtual" receivers in the Transponder Database. A "Virtual" receiver is
added at one of the 15 points allowed per SE coordinator. However, there is no physical
hardware used. The "Virtual" receiver is intended to compensate in cases where there is
an SE receiver imbalance. For example if a building with a dense population of SE
receivers is adjacent to a fence with few SE receivers and an alarm occurs between them;
the alarm location may pull towards the building. The "Virtual" receiver references to
other physical SE receivers that must be on the same SE coordinator. Only if both of the
referenced SE receivers receive an alarm transmission, then the "Virtual" receiver will be
added to the alarm as if was a physical SE receiver that heard the alarm at the average
receive level of the two reference receivers.
The "Virtual" receiver's location and sensitivity may be adjusted the same as a physical SE
receiver. After a "Virtual" receiver is added, verify the surrounding areas to make sure
they have not been adversely affected. In no event should a "Virtual" receiver be utilized
as a cost savings measure to avoid the installation of an actual SE receiver.
