The generator here at work is having a bad day.  the battery charger isn’t working or the battery itself is dead.. either way.  the alarm that keeps an eye on all the critical parts of the generator has this high piched continous beep that sounds to alert us of the problem.  We’re trying to manually charge the battery but no luck yet.  meanwhile, everyone in the building is having to put up with this annoying sound until the problem can be corrected.
