When I had a detector which refused to acknowledge its new battery and kept beeping in that annoying "low battery" way, I called the guys at Public Safety -
not 911.
They came out within an hour in, yes, the biggest d*****d fire truck I think I'd ever seen (the whole street had heartburn wondering about what the h*** was going on). With my profuse apologies for having called them out, they smiled and said, in effect, "No problem!"
Quite honestly, even though it seems like a huge imposition, I'd rather have them come because I feel uncomfortable up on an inadequate ladder then to have them come because I've fallen off that ladder!
