For the past 6 hours (first heard it when I got home from work at 7pm and it’s now 1am), something has beeped very loudly every 60 seconds. I live on Linden Ave and it seems to be coming from somewhere near the YMCA. It sounds like the beeping when your fire alarm battery needs to be changed, but it is loud enough to be heard several streets over (inside with the windows open). I walked up the street but I could not find the source and I don’t know what to do. It’s very annoying.
