I have a 9800 scantronic alarm which has suddenly given a bF alarm whilst not set. I have removed the battery and found it to still be 13+v, which appears OK. I replaced the battery a number of years ago under different symptoms. The control panel does not now give a signal when the access door is being used, this happened a while ago. Is it a batery fault or is it a problem with the control unit. I would like some guidance please.
How many times Acorn have we typed the answer to this one out.
Dennis regardless to how able you are to read a multi-meter , IT IS IMPOSSIBLE to test a battery with a multimeter, Anyone who tells you different, dosent know what they are talking about.
As Acorn rightly says the panel knows whats wrong.
