Sensitivity:
It means the sensitivity of detection. You can only set sensitivity in
‘Manual’ Setup method. In most of the cases sensitivity setting is not recommended.
Speed:
It is the motion speed range which is identified by the detector.
Note: Too big speed range has higher false alarm rate, too low speed range has poor
sensitivity.
Signal:
Shows the signal between transmitter and receiver.
Save
alarms:
It is a useful function if the installer is alone. With this function you can
count alarms, so you can check your detector with test crossings. With ‘Reset’ button you
can reset the counter.
Main Screen: Black line – averaged signal. Changing depending of influence to
detection zone from intruder and and other objects (see 2.1.3.).
Green
and
Blue
penetration thresholds levels work as one. Intruder detection in the
middle of detection zone. Alarm is generated then average signal crosses both penetration
threshold levels for 0.5 sec. time.
Red
penetration threshold level. Intruder detection in the middle of detection zone.
Alarm is generated then average signal cross penetration threshold level for 0.5 sec. time
2.5.4. Sensor adjustment with PC
2.5.4.1.
Perform a preliminary adjustment of Tx and Rx with a sight leaf (i. 2.4.1).
Check if the switcher of sensitivity of the receiver switched to
position.
2.5.4.2.
Before any changes in Setup bookmark, you need to calibrate your detector.
You can make it if you select Calibration bookmark.
