My system suddenly sounded internally today.
The keypad display reads fuse/battery fault.
The 7ah battery was replaced in December 2019
I checked the in line battery fuse and the other two on the pcb all are ok.
The voltage of the disconnected battery is slightly low at 11 volts.
And measuring the voltage at the panel battery terminals with the battery disconnected is 6.5 volts, this seems low to me.
Can anyone offer advice please.
