Wichita has suffered 52 fire deaths since 2006, and in most of those incidents, a smoke alarm was present.
The problem is, in most of the cases, the smoke alarm wasn’t working, Wichita Fire Department data shows. At least investigators couldn’t verify through witnesses that it had activated. Because fire alarms can survive fairly far into a fire, firefighters can sometimes tell if the alarm activated because they can hear it when they arrive, Fire Marshal Brad Crisp said.
I can't imagine that Wichita is much different than other cities. Have you checked yours lately?
