Conveniently, the beeping smoke alarms often beep at a frequency that exits older individual’s hearing range

Also there is simply not enough smoke detector safety education right now. I only learned about the 10 year life space of smoke alarms when one in a rental started alarming as it’s “it’s been 10 years replace me!” warning (and being a super young adult I had no clue what to do and called the fire department which was quite a way to start my day)
