Alarm Light Blinks Three Time And Gate Won't Move

Yesterday I drove back home, I used my remote to open the gate and everything was fine. Few seconds later I tried to close it but nothing happens, not even with the built-in digitpad, and I heard some clicks coming from the control box. This is where i realized that the Alarm light blinked 3 times.
