+---- Thread: SRN- is at 10V instead of 0V (/thread-2635.html)
- TheMax74 - 12-09-2011
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.

Try connecting a 1K resistor between SRN+ and SRN- in case there is soime leakage current
