After creating a new game with the kids, dispatching them to various rooms and back before the alarm goes off, we have determined that b is set to more or less how I'd like it at night. I appreciate the replies. Thank you

Thanks for the replies, The system was last serviced in February 2020 as a condition of the sale to us, so in that respect it should be in full working order and having set it on a and also done a walt test all the sensors and door sensors are working. I will have a try arming b later and see what is armed and what's not. The manuals for the 9851 system came in a huge bundle of manuals and docs from when the house was built in 2006 and the panel model is the 9930 model. 9851 is displayed on the screen of the control panels. I will have a browse through the manuals further to see if I can find out how to default the engineer code. I'm not going to mess about with it really as I don't want to break what seems to be a fully working system. I have a dog, he's bloody useless! Thanks again.

I've moved into a new house which has the hardwired scantronic 9930 control panel and what I think is the 9851 system. I have successfully managed to change the user number. As far as I can tell and is marked on the control panel arming A arms all areas. There is no indication for what arming b, c, or d. Arming b arms something, I just don't know what. I'd like to set b up for a night mode, but the engineer code in the manual isnt working when trying to get into programming mode. I know you wont give any codes. Trying to ascertain if the engineer code could have been changed by someone and thats why the default code doesn't work? I'm following the manual when the system isnt set and pressing 0 followed by engineer code which give me "invalid code". I've hunted around to see if I can find something written down somewhere and no joy. Any advice? Thanks
