Troubleshooting
What to do if the Sensor could not count?
1
Check whether the host signal lines are connected firmly with the door panels.
2
Check whether there is any infrared interference beside the device, such as infrared
surveillance system, infrared remote control, outdoor sunlight, etc.
3
If both a and b are OK, replace the infrared sensor.
What to do if the detector gives a false alarm?
1
If the device gives false alarms frequently after installation, perform the following steps:
a)
Firstly, check the installation environment. Make sure there are no movable or
stationary large metal objects around 1.5 meters from the detector. If there is any
metal object, try to place the device away from the large metal objects.
b)
Make sure that the installation location is stable and free from physical
movements.
2
If the false alarm is not caused by the environment, reduce the sensitivity level of all
zones.
3
Change the frequency.
4
Change the installation location.
