Hi everyone.

Got mi alarm running, had the idea to add a second siren (an external one)

Installed it paralell to the existing one (bell output) wich had already a resistor added (paralell too)

It worked for a few days but now it dos not: no audible sound from the new one, and a little, almost unhearable sound from the older siren.

What could have happened? Culd have burnt the sirens connecting that way? How can I check it the sirens are OK, or troubleshoot at all

Thanks!
