*** I hade 2 in my house, each end.
***
*** The kitchen one saved my live in 1993 when my chimney caught fire from a crack in the fireplace fire wall.
***
*** FD said I would never have awoke (from the smoke) if it had not gone off.
***
*** FD said it was 5 minutes from the rafters.
***
*** Came out fine, insurance only had to replace a part of the den wall & scrub and dry clean stuff.
***
*** Now have 3 detectors and check regularly.
