Re: Smoke alarm placement
In addition to be spaced out from the wall and the ceiling, they have to be located away from air disturbing sources.
Many smoke detectors used to say to place 5 feet from an air disturbing source, however, I believe most are now saying 3 feet.
Some examples of air disturbing sources are:
- supply registers
- return air grilles
- the ends of ceiling fan blades (figure a 52" ceiling fan is 26" from center, plus 36", equals 62" from center of its box to the smoke detector)
