Hi Bill... If you're talking about the "Jacks Deployed" alarm, I know what you mean. That's an irritating horn. This is just a suggestion, but I'd recommend that you leave the audible alert functional - here's why. Among other things, I taught emergency procedures to pilots and crewmembers for years - in aircraft and in flight training devices (simulators). It never ceased to amaze me how often pilots (including me) missed Caution Lights that illuminated right in front of us.
Audible alerts for certain emergencies are just more noticeable than visual alerts. It's a Human Factors thing. I considered installing a switch to interrupt the power to the horn, which would be handy when I was stopped and setting up, or breaking down my campsite, but decided against it. I was concerned that I'd forget to reset it, and if my jacks ever deployed while driving (unlikely, I admit) It would be an expensive mistake - a preventable expensive mistake.
