Smoke rises. Smoke alarms should be located up high, either on a ceiling (minimum of 4” away from a wall) or on a wall (between 4” – 12” down from the ceiling). Smoke alarms must be installed in accordance with manufacturer’s guidelines, but this graphic can be used as a general guideline for where to place them.
In rooms with peaked or sloped ceilings, smoke alarms should be installed near the top of the ceiling. They should be at least 4” down but must be placed within 3’ of the peak measured horizontally. Smoke alarms must be installed on peaked / sloped ceilings in accordance with manufacturer’s guidelines, but this graphic can be used as a guideline for where to place smoke alarms in rooms with peaked / sloped ceilings.
