Security Escort
This will offset the RSSI value by adding or subtracting to it, before the value reaches any
calculation for SA% or Location. When RSSI value after offset is greater than 255, the result
would be set as 255. When RSSI value after offset is less than or equal to 0, the result would
be set as 1.
Note that the RSSI Offset is not applicable to virtual receivers.
Selecting "Virtual" receiver as the Point Type
Use the "Virtual" selection when there is no physical device connected at this bus location.
Starting with version 2.03 of the Security Escort software, you can add
"Virtual" receivers in the Transponder Database. A "Virtual" receiver is added at one of the 64
points allowed per transponder. However, there is no physical hardware used.
Figure 4.12: Data Entry after Selection of Virtual Receiver Point Type
The "Virtual" receiver is intended to compensate in cases where there is a receiver imbalance.
For example, if a building with a dense population of receivers is adjacent to a fence with few
receivers and an alarm occurs between them; the alarm location may pull towards the
building. The "Virtual" receiver references two other physical receivers that must be on the
same transponder. Only if both of the referenced receivers receive an alarm transmission,
then the "Virtual" receiver will be added to the alarm as if was a physical receiver that heard
the alarm at the average receive level of the 2 referenced receivers.
Both the referenced receivers are configured in the Receiver 1 and Receiver 2 fields. These
are the two receivers, on the same transponder, that a "Virtual" receiver assumes the average
of. Both receivers must receive a signal before the "Virtual" receiver reports it also received a
signal that is the average of the other two receivers signals. The location algorithm and
sensitivity adjust work the same for a "Virtual" receiver as for a physical receiver. Enter the
receiver's Point Number in the fields, or click the [?] button to select the receiver accordingly.
The "Virtual" receiver's location and sensitivity may be adjusted the same as a physical
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 receiver.
Setting the Floor Level, Location and Map
Use the Floor Level drop-down list box to assign the physical floor level where a receiver is
mounted at.
The Location field contains the text to be displayed on the Alarm Screen, if this receiver is one
of those closest to the alarm source. The description is developed with the guidance of the
security personnel who must respond to an alarm. It is vital that the description be clear and
unambiguous to them.
