Hi,
Last night my siren has started to sound without any alarm.
Today i disconnected the siren and found that betwteen SRN+ and SRN- there is 10V.
Between SRN+ and COM there is 13.4V.
The checkbox "Reverse siren" is set to "Yes"

I have then set it to "No" and i've measured again 10V.
I suspect a faulty board.
Is there something i can fix by myself?
Thanks.
