Application of the IT 44

The IT 44 is a most useful tool for checking the alignment and sensitivity setting of the detectors. It greatly
facilitates the optimisation of an installation to suit a particular site.

The IT 44 is particularly helpful in situations where a detector is operated under conditions near the
recommended operating limits of height, detection range and target speeds. The information supplied by
the IT 44 display should be used to monitor the detection performance of the detector and make
adjustments if required.

Depending on the site’s animal activity, vegetation moving in the wind and/or other sources of disturbance
it is possible that unwanted alarms occur. Monitoring and interpreting the information supplied by the IT 44
will help finding the best solution either by adjusting the alignment and/or sensitivity of the detector or by
removing disturbance sources from within the field of view.

PIRScope Software for PIR-150

For Display of Signals on a PC Screen Using the IT 44 as Interface Unit.

Procedure

1.

 

Connect the PIR-150 to power and connect the IT 44

2.

 

Connect the IT 44 output with COM port of the PC

3.

 

Load the file „PIRSCOPE.EXE“, enter language and number of COM port

4.

 

Adjust display using the keys as defined on screen

5.

 

Display will show signal amplitude (green), threshold (red) and alarm output (yellow)

6.

 

Press „H“ to save a display in the active directory. A file will be generated and saved as
„DDMMYYAB.BMP“ where AB are used for identification of files within one day.

Note

 

When walk testing the PIR-150 make sure that the 

ATD (Adaptive Threshold Decoding) is

deactivated (switch closed)

, otherwise the detection will become poor due to gradual increase of the

threshold.

 

Running „PIRSCOPE.EXE“ under Windows may lead to problems therefore exit Windows and 

start

computer under DOS

 to run the program.
