I don't have access to the panel right now, but will post a drawing of the wiring below:

If I measure the voltage between the output 12v terminal and output 1, when active it reads around 10.6V that doesn't seem to be enough for my siren. If I measure across the 12v input itself (from the PSU), I get 12.6v. If I connect the siren direct to the 12v PSU terminals, it sounds normally.
