Hello Everyone. I had trouble come up on my alarm the other day and turned out to be the battery so I replaced. After this I thought I would do a test on everything and then found the strobe and siren did not work. I found the the strobe had filled up with water( only 2 years ago replaced for same reason), I went and brought new kit and installed this.
When I tested the strobe works fine but I was not getting any siren. I checked all setting that I could find and I could not get the siren to work, unless I went and turned it on from Outputs menu and it then sounds so it is wired correctly but just will not make sound if I test or set the alarm off.

Any ideas as it is like the system does not see the siren any more, and no settings have been changed since it was last working.

Cheers
