【 FAQ 】
1.The reason that Infrared does not count while installation.
1) Please check if there is no tightening of the left and right door detection head of the
main host.
2) Please check if there is infrared interference near the left and right side infrared
head. (i.e.: infrared CCTV camera, infrared remote controller (when pressing the
button), outdoor sun exposure and so on.
3) If there’s no problem with both 1) and 2), please change and replace the infrared
head.
2.The reason of false alarm while installation.
1). After installed the walk through metal detector, there is frequently false alarm
while testing. Firstly have a look at the installation environment, (should be no any
moving or static large metal objects at the distance of 1.5M!) If there’s big metal
object,please try to keep the walk through metal detector away from it. Also, please
pay attention if there’s wind in installation area which may cause door shaking. If
there’s wind, suggest customer take wind protection measures or replace the
installation location.
2) After installed the walk through metal detector, there is frequently false alarm
while testing. ( If it is not an environmental factor, we can reduce each zones
detection sensitivity first & see if there’s less false alarm. But, if still high false alarm,
then we need to try the following method .
a, After installed the walk through metal detector, if there are false alarm frequently
while testing, (If the voltage is within the normal range, then it is necessary to replace
various frequencies in the oscillation) then test again.
b, Make sure there is no Frequency Conversion Equipment working near the device.
Such as, elevator that with a frequency converter, or the injection molding machine,
etc., because these machines will cause serious interference to walk through metal
detector while working .
c, If none of the above methods can handle the interference, suggest customer change
the installation location then retry. Generally with replacement of the installation
location can handle the interference problems.
