optima xm6 alarm internal sounder has gone off and highlights tamper on the control panel. I have tested the battery with a multimeter which shows an output of 12v dc but i also tested the battery +ve and -ve leads off the board and that gave a reading of approx 11.08 volts dc. Is the battery (which is now 5 years old)on the way out or is the boards output not enough to cause a tamper fault on the board?
Thank you for your help
