Test Individual Devices, Card and
Code Input
Use the following steps for troubleshooting 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.
1
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.
2
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.
3
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.
4
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.
