ALH has a feature where you can set the beep severity for the entire alarm handler or individual PV's. The alarm will still show up for minor alarms, but you don't have to hear them. There are also the silence for one hour and silence forever options so that the alarms are visible, but not beeping.

As an AlarmHandler user it has always struck me that there should be a better way to manage alarms. In the real world it is quite common to have a device sitting just on the edge of the MINOR alarm point, creating nuisance alarms. We do not generally manage alarms by actively changing HIGH or LOW, since these are set by system experts. This leaves the user with the choice of disabling the alarm, which means that if the device reaches the MAJOR parameter no alarm will be heard or dealing with the nuisance alarms. Bad enough when a single channel behave such. When you have thousands of channels, not uncommon for a few to have this problem, especially during times of general machine instability, such as start up. It would be nice to be able to separately acknowledge or bypass MINOR alarms, a kind of "yeah we know we need to look at you, you're alright for now call us when you get to the MAJOR setpoint.
