My smoke alarm had been going off every ten minutes for the past three hours. I really, really, hate this thing. When I first moved in, it needed its battery changed, but since my ceilings are like fifteen minutes high it's not reachable without a latter. And it's wired to the wall, so even when the battery is completely dead it will still chirp at you. I had three awful days before my mother found a handyman with his own latter to replace the battery.
I wish he'd just cut the wire, because it's right next to my stove and always goes off if I use the front burners, always goes off if I open the oven, and always goes off if I cook anything high in fat on the back burner for too long.
So any rate, now it's beeping instead of chirping, and at more frequent intervals, and of course it started doing it basically right after Home Depot closed. Googling, the best-case scenario it's the humidity, which is at 80% in Austin right now, which means that I don't have to do anything about it but also means I can't do anything about it and I'll probably have this problem everytime humidity goes above 70.
The other possibilities are that there's dust in the sensor or that the ten-year-old alarm is dying. Both of which mean I have to go to Home Depot and rent a ladder and probably a truck to carry it, but at least it's fixable. Except Home Depot doesn't open for another four hours.
In the mean time, I decided to open all the windows and run the fan, figuring that if it's dust, fresh air might help, and since it's cooler outside it's probably dryer outside. Now the alarm is going off every two to three minutes, so either it's a dying alarm that's dying faster, or it's more humid outside and I made it worse. I turned the AC on and set it to 58 which is a ridiculous temperature especially considering that I'm going to run the heat to get it back up, but my hope is that at some point, the AC will drop the humidity enough that the alarm stops.
