Test Individual Devices, Card and
Code Input
Use the following steps for troubleshooting individual devices or
keypads. Keep thorough notes during troubleshooting to compare
against and to help find problems, prevent confusion, and save
time if site service by a technician is required.
Try a code or card at the keypad controlling the gate. Ensure
the code or card is one that works at that location and time. Try
several codes to verify operation. Note which code(s) were used
and the response at each device, as well as the response on the
software event log.
Try the same code(s) or card(s) at other access devices on the
property. Compare the result with the previous step. Try to
narrow down whether multiple devices are affected or just
one.
If only one device is not working, determine if the problem is
in the device or the location. Make sure to allow for customer
access, then remove the faulty device. Switch the faulty device
with a similar device that works and remember to switch addresses
too. If the problem remains in the same location, it is probably
a wiring issue. Contact a service company to check the wiring.
Verify that all devices are receiving enough power. Create a
voltage map of the site by sketching out the locations of every
AI device on the site. Use a multimeter to take DC power readings
at each device. Note these readings on the sketch. Any device that
is receiving less than 12V is underpowered and can cause the entire
system to lock up.
