keyword=gas shed audible alarm
There was an audible alarm noticed by the security guard in the gas shed. We went out and pressed the button on the right barnk of the argon. This shut off the audible alarm. We had previously noticed that the argon bottle had switched (at some point pressure got down to 200 then we noticed it was back up to 2000 a little later indicating the switch).
