Troubleshooting
Gatekeeper’s Power Button is Not Turning On
The Gatekeeper’s power LED should turn on when it is connected to a power supply. If it is not
turning on when it is plugged in then:
● Test the power supply by disconnecting it and checking that it the power supply works
○ Unplug the power supply from the socket on the Gatekeeper
○ The power supplies we send have a red LED that should light up if it is working
○ If the power supply is not working, check that it is plugged into a working outlet.
● Having confirmed that the power supply works, reconnect it to the GateKeeper.
● If nothing happens, either the cable from the power supply to the Gatekeeper unit is faulty,
or the plug has incorrect polarity.
○ The polarity of the plug can be changed by removing the tip and rotating it 180
degrees about its long axis. The arrow should indicate this symbol:
● If the LED on the power supply goes out, this indicates an electrical fault. It could be:
1. A wiring fault (short circuit) somewhere on the card reader cable
2. Something on the card reader cable is consuming too much power
3. a bad power supply
4. a faulty Gatekeeper unit (unlikely).
Gatekeeper’s Ser1 and Ser2 Light/s are Not Turning On
When the access control units are plugged into the back of the Gatekeeper, the Ser1 & Ser2 lights
should be flickering to indicate that the Gatekeeper & the access control units are talking to each
other. If it is not, check either the Reader 1 & Reader 2 lights are on. See the next point.
Gatekeeper’s Reader (1&2) LED Light/s are Not Turning On
When the access control units are plugged into the back of the Gatekeeper, the Reader 1 &
Reader 2 lights should turn green . If they are not turning on, this indicates that the Gatekeeper is
unable to see the reader. This may be due to:
● incorrect wiring
● a faulty cable
● a faulty reader
