It’s funny, I recall only asking:-
“Can anyone please suggest what code I can input? I think <eng code> 053 might do it, but until we have another mains failure I can't be certain I have input the right code”
and yet it turns into a typical social media lecture about annual maintenance, how I should use my alarm overnight and if I go into the garden, neighbours not maintaining their systems, the council impact, house insurance ... and all I wanted was a simple freaking code. A simple there isn't a code to turn off the internal sounder would have done fine.
Don’t bother replying as I will not be returning to this site.
Thanks.....
