Summary:
The placement of smoke detectors is regulated by various codes and standards. The NFPA (National Fire Protection Association) requires AC-powered, interconnected smoke alarms to be installed inside each bedroom, outside each bedroom area, and on every level of the home. They also require a minimum of two AC-powered, interconnected smoke alarms in any new construction home. The NEC (National Electrical Code) states that smoke alarms should be installed inside each bedroom, outside each sleeping area, and on every level of the home, including the basement. In Georgia, smoke alarms are required in all residential dwellings and must be hardwired, interconnected, and UL-listed. When installing smoke detectors in a room, it is recommended to mount them on the wall, four to 12 inches below the ceiling and away from corners. They should be placed high because smoke rises and should be kept at least three feet away from air registers, doorways, and windows.

The NEC code for smoke detector placement requires installation inside each bedroom, outside each sleeping area, and on every level of the home, including the basement. It also suggests installing alarms in the living room or near the stairway to the upper level on levels without bedrooms.
Yes, the state of Georgia requires smoke detectors in all residential dwellings. Smoke alarms in newly constructed or renovated dwellings must be hardwired with a battery back-up, interconnected, and UL-listed.

What is the code for hardwired smoke detectors
NFPA 72
The National Fire Alarm Code (NFPA 72) requires hard-wired, interconnected smoke alarms with battery back-up on every level of the home, outside each sleeping area, and inside each bedroom. Alarms must be wired together so that if one sounds, they all sound.
What is the NEC code for smoke detector placement
Install smoke alarms inside each bedroom, outside each sleeping area and on every level of the home, including the basement. On levels without bedrooms, install alarms in the living room (or den or family room) or near the stairway to the upper level, or in both locations.

Where should smoke detectors be placed within a room
If you mount it on the wall, place it four to 12 inches below the ceiling and away from corners. Keep them high because smoke rises. Never place them any closer than three feet from an air register that might re-circulate smoke. Don't place them near doorways or windows where drafts could impair the detector operation.
How far does a smoke detector have to be from a vent
3 feet
– Within 3 feet of an air supply vent (supply or air flow) – Within 1 foot of a light fixture. – Within the “dead air space” where the wall meets the ceiling (ceiling smoke alarms must be at least 4” from the wall, wall mounted smoke alarms must be at least 4” and no more than 12” from the ceiling.

Which is better wired or battery smoke detectors
Hardwired smoke alarms are powered by 240V mains power and also have a backup 9V battery. This offers the added security of having 2 sources of power in the case of power failure, which makes them much more reliable than battery-only smoke alarms. Keep in mind that the 9V battery still has to be replaced every year.
