I configure my alarms with FanCmd is monitored variable and FanSts is shunt variable. So when shunted (Cmd=On and Sts=On), the alarm is Disabled. I consider Disable to be a NORMAL condition.
Also Disable is the state of the alarm if no monitored variable is bound.
Reminder: use the Integer Input to bind to the AlarmState from the alarm object directly or multistate value. It is in the video, of course, but since I rarely use it I forgot and used an Real Input, which does not bind.
