Summary of the Article:
According to the National Fire Alarm Code (NFPA 72), heat detectors on smooth ceilings should be spaced 50 sq. ft. or 2500 sq. ft. The maximum floor area covered by a heat detector is 37 m². In compliance with NFPA, smoke alarms cover a radius of 21 feet and an area of coverage of 1,385 square feet. Heat detectors should be installed in every bedroom in the house, outside each sleeping area, and on every level of the house. They should not be installed near vents or air ducts and should be placed high up off the ground or ceiling. Ideally, heat alarms should be installed in the center of the room/space, such as the kitchen, garage, and loft. They should be placed 300mm away from walls and light fittings. All points on the ceiling should have a detector within a distance equal to or less than 0.7 S (S is the listed Spacing).
Questions:
1. How many square feet does a heat detector cover?
A heat detector covers 50 sq. ft. or 2500 sq. ft. (according to NFPA 72).
2. What is the maximum floor area a heat detector covers?
The maximum floor area covered by a heat detector is 37 m².
3. What is the coverage area of a fire detector?
In compliance with NFPA, smoke alarms 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.
4. Which area in a home is required to have a heat detector?
Heat detectors should be installed in every bedroom in the house, outside each sleeping area, and on every level of the house.
5. Where should a heat detector not be installed?
A heat detector should not be installed near vents or air ducts that may cause interference. Its vents should be easily accessible, and it should not be blocked by other objects or obstacles. It is recommended to place the device high up off the ground or ceiling.
6. Where should a heat detector be placed?
Heat alarms should be installed on the ceiling, ideally in the center of the room/space, such as the kitchen, garage, and loft. Sufficient alarms should be installed to compensate for closed doors and obstacles.
7. What is the best location for a heat detector?
Smoke alarms and heat alarms should be placed on the ceiling, as centrally as possible within the room/area they are installed. They should be situated 300mm away from walls and light fittings to ensure they are away from any “dead air” spaces that occur in corners and spaces where the airflow may be blocked.
8. What is the coverage area for a heat detector according to NFPA 72?
All points on the ceiling should have a heat detector within a distance equal to or less than 0.7 S, where S is the listed Spacing. The equal spacing for smoke detectors is 15.2 Mtr, whereas for heat detectors, it is 9.1 Mtr. The spacing between detectors must not be less than 0.4 S.
How many square feet does a heat detector cover

What is the maximum floor area heat detector covers
Heat Detector:
1. Maximum floor area per detector = 37 m². 2.
What is the coverage area of a fire 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.
Which area in a home is required to have a heat detector
The Right Room
Don't just install these in one bedroom. You need to put them in every bedroom in the house. In fact, this is recommended by the NFPA. At the very least, you need to have a smoke and heat sensor outside of each sleeping area and on every level of the house.
Where not to install a common heat detector
A heat sensor should be placed away from any vents or air ducts that may cause interference. The sensor should have its vents easily accessible, and it should not be blocked by other objects or obstacles. It is recommended that the device be placed high up off the ground or ceiling.
Where should a heat detector be placed
Install heat alarms on the ceiling, ideally in the centre of the room/space e.g kitchen, garage and loft. Install sufficient alarms to compensate for closed doors and obstacles.
Where is the best location for a heat detector
Placing of smoke alarms and heat alarmsAlarms should be sited on the ceiling, as centrally as possible within the room/area they are installed.Site 300mm away from walls and light fittings – this is to ensure that they are away from any 'dead air' spaces that occur in corners and spaces where the airflow may be blocked.
What is the coverage area for a heat detector NFPA 72
All points on the ceiling shall have a detector within a distance equal to or less than 0.7 S (S is the listed Spacing). Equal to S = 9.1 Mtr. For Smoke detector , S= 15.2 Mtr. For Heat detector and the spacing between the detector must not be less than 0.4 S.
What is the range of fire detector sensor
The IR flame sensor is used to detect the presence of fire or other infrared source (Flame or a light source of a wavelength in the range of 760 nm to 1100 nm can be detected).
Where should I install a heat detector
We recommend placing them high off of the ground or on the ceiling. This is because heat rises, and you will want the sensor to pick up the change in temperature in the event of a fire. Finally, the device should be placed in an open area, and it should not be blocked by other objects or obstacles in the area.
What are the disadvantages of heat detector
Disadvantages: In the event of a fire, heat detectors respond only if temperatures rise very quickly or if the static response temperature has been exceeded.
Does a heat detector have to be on the ceiling
Heat alarms should be mounted either on the ceiling or the wall. We recommend you install a heat alarm in areas where temperatures may be extreme; such as in an attic or garage.
What is the maximum distance between heat detectors
Max distance between 2 heat is 9m.
Should heat alarm be on wall or ceiling
Where should we site the smoke alarm or the heat alarm This kind of alarm needs to be positioned on the ceiling, as centrally as possible within the room or area where they are installed. The alarms should be located 300mm from walls, light fittings, or any other obstructions.
What is the radius range of a heat detector
HEAT DETECTOR
When mounted on a flat ceiling, heat detection devices have an individual coverage of 5.3m radius. However these radii must overlap to ensure there are no 'blind spots'.
What are the requirements for NFPA 72 heat detectors
NFPA-72 requires heat detectors to be rated at least 20-degrees above the ambient ceiling temperature. NFPA-72 also requires a color-code designation to help identify different heat detector temperature ratings. The colors and the associated temperature (Fahrenheit) are as follows: 100-134 (Low) = Uncolored.
What distance does a smoke or heat detector cover
Since heat detector spacing typically ranges anywhere from 15 feet to 50 feet, this illustration cannot be applied. While the Point 7 Rule can be mathematically calculated for heat detectors and applied to rectangular area and corridor applications, thankfully, the math has already been done for us in NFPA 72.
How many heat detectors do I need
At least one smoke alarm in every circulation space on each storey (such as hallways and landings) At least one smoke alarm in the principal habitable room (generally the living room) At least one heat alarm installed in every kitchen.
Should heat detector be on wall or ceiling
Install heat alarms on the ceiling, ideally in the centre of the room/space e.g kitchen, garage and loft.
Where should you use a heat detector
Smoke alarms detect smoke – fit them in all rooms where a fire might start. But in smoky or steamy rooms like your kitchen or bathroom, a heat alarm is more suitable. These alarms go off when the room reaches a certain temperature.
Where is the best place to put a heat detector
ceiling
Install heat alarms on the ceiling, ideally in the centre of the room/space e.g kitchen, garage and loft. Install sufficient alarms to compensate for closed doors and obstacles.
