In any room with a ceiling fan, smoke detectors should be installed at least 3 feet away from the fan blades, but preferably still on the ceiling. This will help to avoid any interference with the proper function of the smoke alarm.
How far away should a smoke detector be from a ceiling fan?
Make sure smoke detectors are at least 18 inches from a corner. Do not place a unit on an uninsulated exterior wall or ceiling. Place smoke detectors at least 3 feet from ceiling fans.
How close should a smoke detector be to a bedroom door?
The locations for ceiling-mounted smoke detectors installed on a smooth ceiling for a single or double doorway must match the centerline of the doorway no more than five feet from the door and no closer than 12 inches to the doorway.
Should smoke detectors be on the ceiling or wall?
Smoke alarms should be mounted in or near bedrooms and living areas, either on the ceiling or the wall. Ceiling mounting it is typically preferred as it allows the smoke alarm to be placed more centrally in the room.
Do smoke alarms have to be on the ceiling?
Smoke alarms should ideally be installed in the centre of the ceiling. As hot smoke initially rises and then spreads out, smoke alarms should be located on the ceiling. This is so that smoke can reach the detector’s sensor chamber as early as possible.
Where should smoke detectors be placed on ceiling?
Make sure smoke detectors are installed high on the walls or near the center of the ceilings, and at least 10 feet away from cooking appliances. When installing on the wall, place the smoke alarm at least 12 inches from the ceiling. This is because smoke rises and will make the alarms the most effective.
How far away from wall should smoke detector be placed?
For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
What is the distance between smoke detectors?
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.
Where do you put a smoke and heat detector?
Smoke alarms can be fitted in hallway, landing, living room(s), bedroom, airing/meter cupboards. Heat alarms are best suited to areas where dust, fumes and moisture can cause nuisance alarms in smoke alarms. Designed for use in for a kitchen, laundry/boiler room, loft, garage.
Where should I place my heat detector?

Does ceiling height affect smoke detector spacing?
The current code requirements for smoke detector spacing state that the maximum distance between detectors is a nominal 30 feet, and the distance between detectors must not exceed half of the nominal spacing measured from the wall or any partitions within the top portion of the ceiling height.
What is the 0.7 rule?
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.
Where do you mount carbon monoxide detectors?
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.
Can you install smoke detector on drop ceiling?
The base of the smoke detector must be anchored to a surface solid enough to support the smoke detector’s weight. This is achieved in the case of a drop ceiling by backing a ceiling tile with a stronger material so that the smoke detector will be properly anchored.
Where should smoke detectors be placed in a house UK?
Smoke alarms are usually screwed onto the ceilings, although specialist sticky pads can be used, and should be fitted as close to the centre of the room as possible, but at least 30 centimetres (12 inches) away from any wall or light fitting.
