arming

I just bought a 2006 Cupra 1.8T. When I lock the car via remote, I dont get any flashes from sidelights and when I tried to enable horn beeping for locking, it doesnt work. Unlockign is OK. Manual says that if the car thinks a door, boot or hood is open, it will lock the car up but dont give any...

Am I right in saying it is possible to lock the car without arming the alarm if you press the lock button twice? If so is there a sequence? I have tried pressed the lock button in quick succession with no success, do I need to wait for the car to lock and then press the button again?? :confused:
