4.2.4 Adjusting Detection Ability
Adjust the detection ability to improve the accuracy rate of detection.
●
The detection sensitivity reduces from the two sides to the middle area, so the detection ability in
the middle area is the weakest.
●
When detecting the detection ability with a flat metal sheet. Do not make the flat panel parallel
to the door panels; otherwise the alarm will not be triggered.
●
It is easier to detect the metal objects with good magnetic property than the ones with poor
magnetic property.
Step 1
Select the installation scene as needed.
Step 2
Close both infrared groups, and then adjust the safety level and sensitivity until there is no
false alarm caused by ambient environment.
For details of closing both infrared groups, see "4.2.3.6 Setting Infrared Start-stop".
Step 3
Test the detection ability of each zone with a metal object. If the alarm is not triggered,
adjust the frequency, and then do Step2 and Step3. Repeat the operations until the
detection ability meets your demand.
Step 4
Enable both infrared groups.
