Locating the site features and zone boundaries
To draw the perimeter line on a site map, and to accurately display the location of alarms, you
must determine the position of the site’s features and zone boundaries relative to the length of
sensing sensor cable. To accomplish this, one person goes around the perimeter causing
disturbances at all site features and zone boundaries, while a second person monitors the
disturbances in the control room. Create a series of three disturbances at each feature, and use
the average value of the three test results for the feature’s location. The tester requires a detailed
perimeter site plan that clearly identifies each feature and zone boundary that must be located for
the map display.
1.
Make a copy of the Location/calibration table from Appendix c (see
for an example
of the Location/calibration table).
2.
Conduct a series of 3 tap tests at each site feature and Zone boundary location waiting at least
15 seconds between tests. Note the time of each test on the Location/calibration table.
3.
Go to the Log sub-panel, and record the locations of all the disturbances that were created
during the tap tests. Calculate the average location of each series of 3 tap tests for each
feature and Zone boundary location and record the result in the Location/calibration table.
4.
Make a copy of the completed Location/calibration table and keep it in a safe place.
Note
For the Split configuration, begin testing at location 0 (the S1 end
module).
