Boundary areas at the outer edge of the protected area
The system cannot locate an alarm past the last SE receiver at the boundary of the protected
area. Therefore, the last row of SE receivers must be at or past the end of the protected area.

Testing the location accuracy of an installation
Notice!
Before doing any of the following testing, it is important to verify that every SE receiver in the
system is functioning correctly using the procedure described in the Security Escort Hardware
Installation Manual and Software Installation Manual. Additionally, every SE receiver must be
programmed in the Transponder Database with its actual physical location and floor level. It
is also important that SE receivers which are physically stacked directly above one another
on floors of a building are also located at the same X and Y coordinates in the database.

SE receivers should have a clear line of sight of the protected area. Therefore, take care
where the ground is hilly or uneven, that there are no areas and low spots where several
receivers can't hear the signal.
An outside area directly between two buildings with complete indoor protection will need
no additional SE receivers between the buildings, if they are 90 m (300 ft) or less apart.
When protecting an outside area directly between two buildings with complete indoor
protection, and they are more than 90 m (300 ft) apart, place a row of outside SE
receivers evenly spaced between the buildings. Make sure the SE receiver row does not
exceed the standard 90 m (300 ft) spacing from the buildings. The spacing between SE
receivers in that row should be about the same as the spacing for the SE receivers in the
buildings.
However, if a building is adjacent to an outdoor area, that building will have a greater
density of SE receivers and, therefore, has a tendency to pull the computed location
towards it. To counteract the building tendency to pull the location, consider the
following special cases:
–
If the outdoor area adjacent to the building is wide open and the customer is not
concerned about reduced location accuracy in this area, then nothing special needs
to be done. Follow the normal indoor and outdoor recommendations.
–
The building is near the boundary of the protected area, with or without a fence at
the boundary. The SE receivers at the boundary of the protected area near the
building should be spaced about the same as those in the building, approximating
the same grid as used in the building.
–
The building is adjacent to a large protected outdoor area that extends for more than
90 m (300 ft) from the building. The SE receivers in the large protected outdoor area
should be placed on the normal 90 m (300 ft) grid except for the first row of SE
receivers adjacent to the building. This first row of outdoor SE receivers in the
transition area should "split the difference" between the indoor and outdoor spacing
at about 60 m (200 ft).
