What could cause two separate fire alarm systems to go off concurrently ?

Tammie W on Mar 07, 2012did the battery operated trip the hardwire perhaps? sometimes if I bake in the oven too long say a roast or chicken (with opening and closing the oven more then I should) I think the heat drifts up the stairs and trips our battery operated ( occasionally) ...but it doesn't trip the hardwire alarm. Hmmm...thats a mystery. Has it happened before?Helpful Reply

3po3 on Mar 07, 2012Have you been remodeling? I have heard (yeah, I find it hard to believe, too, but I've heard) that paint fumes and remodeling dust can set off sensitive modern fire alarms.Helpful Reply

Madeline C on Mar 08, 2012Thanks for the answers, but I'm still hoping for more ideas. Actually Steve my husband had been shaking a laser toner to see if he could get more ink a couple of hours before. If that was it is still strange that both went offHelpful Reply

3po3 on Mar 08, 2012Did someone take a particularly steamy shower, or did humidity somehow spike right before the alarms went off?Helpful Reply

3po3 on Mar 08, 2012Still, the steam could travel to the alarms. Sounds like maybe a freaky glitch. Clean out both alarms and make sure there is not dust or insects tripping them.Helpful Reply

Madeline C on Mar 08, 2012The firemen checked and cleaned the alarms upstairs. My husband is going to clean the ones downstairs. I was taking a shower on the main level at the time, but why this time and not others? Freaky glitch.....Helpful Reply

Stuart M on Mar 21, 2012They probably just had a build up of dust over time and when you took a shower it was just the final thing it took to cause a false alarm. Smoke alarms should be replaced after 8 to 10 years. Side note; use lithium 9volt batteries they have a life span of ten years, say good bye to the beeping at midnight warning you to change the battery. www.brightenelectric.netHelpful Reply
