Starting with version 2.03 of the Escort software allows individual receiver sensitivity to be
set in the transponder database. Receivers can be adjusted from 50% to 149% of their
normal sensitivity. No physical receiver changes or upgrades are required. This setting
should only be changed if there are known location accuracy problems in the area of this
receiver. Settings of 50 to 99 will desensitize the receiver to 50% to 99% of the actual
received signal strength. Settings of 1 to 49 increase the sensitivity to 101% to 149% of the
actual received signal strength. Try changing the sensitivity of receivers one at a time while
testing the alarm location response. For example if alarms are being pulled towards a
particular receiver, lower its sensitivity in 10% increments and retest. If the area can be
corrected using this method, verify the surrounding areas to make sure they have not been
adversely affected. It is generally better if the correction is done in small steps while
verifying the adjacent areas, rather than trying to correct the entire error in one step.
The SA% option will only be available if the "Enable algorithm tweaks" box is checked in the
System Preferences dialog.. Also in the transponder database there is the Algorithm
dropdown list box to allow selection of DEFAULT, CLASSIC, LINEAR, LOW, MEDIUM or
STRONG pull location algorithms for each transmitter. The point reporting the best reception
level determines the actual algorithm used for location on any event. If programmed for
DEFAULT the algorithm used will be LINEAR for points programmed as outdoor or tunnel
and all other points will use LOW. If the point reporting the best reception level is not
programmed for the DEFAULT algorithm then the location calculation will use the algorithm
programmed.
Defines which bitmap is to be displayed for this receiver or area when an alarm to
determined to be closest to it. The default map is 0, which corresponds to bitmap
MAP0.EDB stored in the Escort sub-directory. Map 1 would be MAP1.EDB. There can be
100 maps per Security Escort system (0-99).
This string will be output on a system serial port that is programmed in the Remote Setup
dialog. The purpose is to display the area, where the alarm is most likely located, on the
CCTV monitors near the Central Console. Therefore the string would activate a macro in the
video switcher that selects the appropriate camera and controls any required zoom and tilt
actions. Up to 40 characters may be entered. Control characters may be entered as "^A" for
control A.
This is the pager group that will be paged if the alarm location is determined to be in this
area.
Determines the floor number that this area is defined on. The areas on floors above and
below this one may be defined differently. In order for an area to be selected when an alarm
is received, the location determined by the Central Console must be located within the
defined area and it must be located on the designated floor.
If this checkbox is checked this area will not be used for normal alarm area location. This
area will only be used to define a "Virtual Fence". Specific transmitters in the subscriber
database can reference this transponder and area. When they reference this area and the
system locates the transmitter position outside the area a Wandering (Virtual Fence) Alarm
will be generated. This alerts the operator and shows the position of the transmitter.
When clicked the transponder's edit dialog will disappear and the cursor will change to a
cross hair. Moving the cursor to a point on the map and clicking the left mouse button will
scroll the map so that point is at the center of the screen and all previously defined receivers
and areas will be shown with numerical labels.
When the map is showing the location of the receiver desired, move the cross hair to the
exact location of the receiver and click the right mouse button. The transponder edit dialog
will reappear and the selected location will be entered into the X and Y coordinates.
When the map is showing the location of the area desired, move the cross hair to the exact
location of the first point of the polygon that will describe the boundary of the area and right
click. Move the cursor to the second point of the polygon and again right click. The computer
will draw a straight line between the first and second points. Repeat this process drawing all
sides of the polygon to define the area. To close the polygon the last point should be placed
on top of the first point. The polygon can have up to 19 sides and no two lines of the polygon
may cross each other. If you try to create more than 19 sides the computer will automatically
close the polygon with the 19
make it more visible. After the polygon is complete double click the left mouse button to
return to the Transponder Edit dialog.
If the area being defined is a virtual monitor "fence" area for Wandering Alarms, the monitor
fence (area boundary) should be drawn at least 8 m (25 ft.) past the area to be protected to
reduce potential false alarms. This is due to the basic location accuracy of the Security
Escort system.
If while the cross hair cursor is being displayed, you desire to exit without changing any
coordinate values, press the ESC key and the transponder edit dialog will reappear.
