who'd have thought a 20 yr alarm panel would be playing up...
remove a rkp off the wall, connect via a flylead to the panel with no other rkp on the system & try to default
apart from 4 rkp what else is on the system
well.... Texecom radio stuff is almost as bad as Risco
Start deleting & changing devices & you soon find the menus are all over the place & far from logical
Product knowledge....
You either find someone to local to work with your alarm (ring risco & ask them for local firm?)
Fanny about with it yourself, (i'm finding life is too short for DIY)
Bin it off & get a new one
