Alerts when in home mode

At night we put the system in 'home' mode... for us this means we have all the door and windows sensors on but also a couple of the movement sensors in the kitchen and dining room on too. We do this because we only have one door sensor on that bit of the house and quite a few windows that could be an entry point for someone just to smash their way in. (This happens quite a bit where we live.) Anyway what is happening is that one of the family comes downstairs in the morning but just forgets the house is alarmed... walks into the kitchen to make a brew and - bam! - off goes the alarm. You would think we would remember but there are five of us and we appear to be equally bad at remembering this.

What would really help us would be if there was a way that the sensor we have on the stairs (which in home mode is off) making some sort of bleepy noise or something when we come downstairs to would remind us that we have an alarmed house.

I have had similar functions on far older alarm systems in the past... these were things like a pressure pad under the carpet on a couple of stair treads etc, basically so you got that little audio reminder to turn the alarm off!

I have gone through this system but can't find a way of sorting this.

Any tips?
