Troubleshooting
What to do if an error is prompted during the auto testing?
a)
When the message "EFT ZONE ERROR RIGHT ZONE ERROR" is prompted during the auto
testing, please pay attention to whether the left and right signal cable plugs are inserted
tightly.
b)
When it prompts "The infrared receiving error", please check whether the left and right
signal wires of the door panel are connected properly, whether the infrared sensors are
connected properly, and whether the two sets of infrared sensors are blocked.
What to do if the Sensor could not count?
a)
Check whether the probe cables are connected firmly with the door panels.
b)
Check whether there is any infrared interference beside the device, such as infrared
surveillance system, infrared remote control, outdoor sunlight, etc.
c)
If both, condition
a
and condition
b
are OK, then the issue is with the infrared sensor
and need to be replaced.
What to do if the detector gives a false alarm?
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 firm and stable and free from physical
movements. If not, change the installation location.
c)
If the false alarm is not caused by environmental interference, then reduce the
sensitivity level of all zones.
d)
Change the frequency.
