The Point 7 Rule.
According to the NFPA, smoke alarms should be placed in every bedroom, outside each sleeping area and on every level of your home. In addition, industry experts recommend having both photoelectric and ionization alarms for optimal protection against flaming and smoldering fires.
One may also apply the rule of . 7 (point seven), in which the ceiling shall have a detector within a distance equal to . 7 times the listed spacing. This is very useful when dealing with irregular areas.
For many years NFPA 72, National Fire Alarm and Signaling Code, has required as a minimum that smoke alarms be installed inside every sleep room (even for existing homes) in addition to requiring them outside each sleeping area and on every level of the home. (Additional smoke alarms are required for larger homes.)
Smoke detectors/smoke alarms should be installed on the ceiling, which is where heat and smoke go first during a fire. Place detectors/alarms as follows: First Floor: Place on the ceiling in a main area, near but not in the kitchen. Second & Third Floor: Place on the ceiling in hallway between bedrooms.
Install a least one on every level of the home, including the basement. Place a smoke detector in every sleeping area. Ensure a smoke alarm is outside of every room, like in a hallway.
Install smoke alarms in all circulation areas/ escape routes and high risk areas. Have at least one smoke alarm in every circulation space on each storey (such as hallways and landings) Position at least one smoke alarm in the principal habitable room (generally the living room)

Because smoke rises, you should place alarms on the ceiling. If you cannot do this, place them high up on a wall according to manufacturer's instructions. Most importantly, read the installation instructions that come with the alarm.
1) Smoke detector spacing should follow NFPA 72 guidelines of no more than 30 feet apart and within 15 feet of walls, or ensuring all ceiling points are within 21 feet of a detector.
Always sell a stock it if falls 7%-8% below what you paid for it. This basic principle helps you always cap your potential downside. If you're following rules for how to buy stocks and a stock you own drops 7% to 8% from what you paid for it, something is wrong.
This requirement is commonly called the Point 7 (0.7) Rule. The most common application of the Point 7 Rule is smoke detectors in corridor applications. Applying the Point 7 Rule allows spacing between smoke detectors to be extended beyond 30 feet in corridors that are less than 30 feet wide.
Install smoke alarms inside and outside every bedroom and sleeping area (like a hallway). Install on every level of the home, including the basement. A smoke alarm should be on the ceiling or high on a wall. Keep smoke alarms away from the kitchen to reduce nuisance, or false, alarms.

A new standard for smoke alarms, which went into effect on July 30, requires smoke detectors to be more sensitive to all types of fire and to have fewer nuisance alarms from cooking. NIST research in a kitchen fire laboratory shows that these smoke alarms still produce nuisance alarms during cooking.
(Although there were some standard smoke signals: One puff meant “Attention”; two meant “All is well”; and three puffs of smoke, or three fires in a row, signified “danger, trouble, or need help!”) The intent was to transmit secret knowledge over distance, so most of the signals were devised privately and for a ...
The NFPA 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.
NFPA 72 requires that all points on the ceiling have a detector within a distance of 0.7 times the listed spacing of the detector.
1 of NFPA 101 requires one- and two-family dwellings to have only an alarm system (no monitoring needed) with audible alarms in the following locations: Within every sleeping room. In the immediate vicinity outside of every sleeping room. On every level of the building (including basements)
Have smoke alarms on every level of your home and in each bedroom and hallway. If you mount alarms on the ceiling, place them 4 inches from the wall. If your alarms are on the wall, they should be 4 to 12 inches from the ceiling. Don't install alarms near windows, vents, or drafty areas.

Where do I install them? In addition to the minimum requirement of one smoke alarm per level, Fire and Rescue NSW research recommends installing smoke alarms in all bedrooms and living spaces (including hallways and stairways) and even the garage. Avoid fitting smoke alarms in or near your kitchen or bathroom.
