How many feet from the end of a corridor shall a smoke detector be placed?
Also asked, what is the coverage area for smoke detector?
In compliance with the National Fire Protection Association (NFPA), smoke alarms will cover a radius of 21 feet, and an area of coverage of 1,385 square feet. The maximum distance between two smoke alarms should be 30 feet. If a hallway is greater than 30 feet, a smoke alarm must be installed at each end.
Secondly, where should a smoke detector be placed on a ceiling or wall? Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimize false alarms when cooking. Mount smoke alarms high on walls or ceilings (remember, smoke rises). Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).
Keeping this in view, how close can a smoke detector be to a return air grille?
NFPA 72 recommends installing smoke detectors a minimum of 3 feet from any air supply or return air grill. They may need to be installed farther away when air velocity is higher than normal.
What is the maximum mounting height of a smoke detector?
According to Section 5.7. 3.2, NFPA 72, 2007 Edition, spot-type smoke detectors can be mounted either on the side wall or ceiling. When using the side wall, mount the device no closer than 4 inches from the ceiling. The maximum distance is 12 inches.
