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.
Where should you install heat detectors?
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.

Do I need heat detector in kitchen?
Heat alarms are recommended for placing directly in kitchens and in unconverted loft space. All alarms should be interlinked (either using hard wiring or wireless interlink) to ensure audibility throughout the property in the event of an alarm being activated.
How much area does a heat detector cover?
For smoke detectors, the individual coverage can be represented by a square measuring 10.6m x 10.6m giving a coverage of 112m² per device, which is usually approximated to 100m². With heat detectors this figure is 7.5m x 7.5m, giving an area of coverage of 56m² per device which is rounded down to 50m².
Where would you use a rate of rise heat detector?

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. This ensures that when detection is used, the entire space on the ceiling is covered by detection. This requirement is commonly called the Point 7 (0.7) Rule.
How many detectors are in a zone?
Zones. Each zone can have max 20 detectors.

Is a smoke detector the same as a heat detector?
Heat detectors are intended to minimize property damage by reacting to the change in temperature caused by a fire. Smoke detectors are intended to protect people and property by generating an alarm earlier in the development of a fire. … Some types of fires “smolder,” or burn very slowly without flames.
Can steam set off a heat detector?
Heat detectors do not get set off by steam or smoke or the normal cooking tempreatures. … Heat detectors are also installed in garages and other areas where smoke or gases are present (with exception of bathrooms).
Can steam from a kettle set off a fire alarm?

Should you put a fire alarm in the attic?
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. … More specifically, install Smoke Alarms: On every level of your home, including finished attics and basements.
At what temperature should a heat detector be activated?
Heat Detectors react to the change in temperature caused by fire. Once the temperature rises above 135 degrees F (57 C) or 194 degrees F (90 C), the heat detector will send a signal to an alarm panel and trigger an alarm.
Are fire alarms heat sensitive?
Temperature. Certain fire alarms are sensitive to heat and will go off if they sense a change in temperature (in fact, most fire alarms are a combination of heat- and smoke-activated). … Think about this—during the summer, unventilated attics can reach up to 120 F or hotter, more than enough heat to set off a fire alarm.
What is a spot type heat detector?
Heat detectors are used in confined areas for detection of fires around hazardous locations. The detector is a thermistor type, enabling adjustment of temperature response by the controller.
Why does my smoke alarm go off when I open the oven?
Your smoke detector may go off when you’re cooking because vapor, smoke, or steam is entering the device. Both ionization and photoelectric smoke alarms are so sensitive to foreign objects that even a cloud of dust could trigger the alarm.
