Hi, given the time of day, I'm awake due to the constant on / off beeping from the 9940 LCD panel, control unit is scantronic 9651.
Now I've been on a few forums, and if I knew the code to enter engineer mode then I'd at least be able to join rest of my family and get some sleep....but I don't know the code.
I'm pretty confident in replacing the battery in the main box (£20 Screwfix) but I fully expect that will lead to a tamper error, which again needs to engineer code to clear.
I could then attempt a reset of default codes (various steps, shorting some pins) but not sure if that also clears the zone programming etc.
Anyone able to offer advice? Or is it a case of spending £150 call out with cost of parts on top....from the suppliers. I haven't had chance to ring around for quotes as yet......
