SLO, that was what I was getting at, same here.... Our fire station has a sign out front and they always put a message out there at DST time. I did not realize it coincided with fire prevention month though. Interesting note on batteries, and time of day.
My os indoor battery indicator went on today also. And for the first time ever I had a dud in the package. Brand new 16 pack of tripple aaa's and the 4th one I put in was completely DOA. Was surprised when I went to scan for it, and the battery notification was still lit.... (and my kepad door lock at the side entrance also died today) Have to make another trip to the Depot. Actually I am using Energizers these days, so its a general battery corp conspiracy

ps: and my thermostat also changed itself, of course since I did not notice, I dont know if it changed old or new DST.... I guess I will check in spring.
How did my smoke alarm (one of them) know it was DST. Started chirping Sunday morning...... One of my battery clocks died as well. Duracell conspiracy...

Because back before Congress messed with DST the last time, Fall Back was in October, which is fire prevention month, and most fire depts used the time change as a handy reminder to tell people it was time to change their smoke detector batteries.
OTOH, they start chirping late at night or early in the morning because that's when the house is coldest, and waning chemical activity is the lowest in the battery, and therefore the voltage is the lowest.
