Walk Test
According to European Standard 50131-2-2, 'Walk Test' is defined as follows:
The walk test is an operating test in which the detector is stimulated by a standard walk test
object in a monitored area.
A standard walk test subject is a person of normal height and weight who is plausibly
dressed as an intruder.
This test is used to install a detector for normal operation, in the best way for the desired
monitoring area, in order to achieve on the one hand the highest possible detection rate
(DR), and on the other the lowest possible false alarm rate (FAR).
The walk test can be performed when installing both hardware and software.
Using the alarm outputs, the test can be performed without auxiliary devices. For a more
accurate and reliable calibration, the use of an optional CT-PRO wireless walk tester, or
connection to a PC via the serial RS-485 interface, is recommended.
8.1.1 Walk Test – Hardware Mode
To perform the walk test in hardware mode, follow these steps:
1.
Keep the default settings of DIP switches 1 and 2,
2.
Set DIP switch 3 to "OFF" to deactivate the adaptive threshold discrimination (ATD)
function. See section 9.2 for further details,
3.

4.
Perform the walk test.
It is recommended that, initially, a preview with a detector pre-adjusted with a
telescopic sight is carried out, according to the corresponding area to be monitored
(see the overview of installed detectors in chapter 20).
Start with the maximum distance.
Proceed at a 90° angle to the longitudinal axis of the area to be monitored.
If there is no alarm in the area you are testing, re-adjust the angle of vision.
If the alarm trigger is correct, next check the lateral areas.
To avoid false alarms, make sure that there is no over-reaching.
Finally, cross the area several times at different distances and in different directions.
After the test
After the walk test, do the following:
1.
Set DIP switch 3 (ATD function) to "ON",
2.
Fix the aligned detector horizontally with a nut underneath,
3.
Fix the aligned detector vertically with a nut on the right side.
