I have an old Optima XM alarm system in my house in which has worked fine for over 20 years. Recently when I was trying to set the alarm to go out, the buttons on the keypad were bleeping as I was trying to set the alarm, but the alarm wasn't setting. A little later I would try again and sometimes it would set but then not be able to unset it.
I know its old but can anyone give any useful advice please, apart from just get a new one
