Siren no longer working

Hey all any ideas where to start here. I have had konnected working for a couple of years now with home assistant with no problems. A couple of months ago my siren stopped working.  The switch is still available in HA just no sound. Not sure if the siren itself is broken or is this is a relay thing on the board or what the issue might be. I got around by trigging sounds on my google homes around the house but would certainly rather have my siren working again. How do I start to trouble shoot this?
