what does the keypad say?did you fit the system yourself?the system can be prog for timed set,final door set,or press button outside to set,or shunt lock,you have a very good panel,so i would check the proggraming of it,when you key in your pin,you should get cont tone excpt when you open the exit door,also check that you have enough time to exit,is there a pir in area of exit that is picking you up as you leave?if the panel times out before you close the door then the panel will not set,and you will get a warning tone from exten speaker,if fitted
