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.
What kind of smoke alarm should I put in a kitchen?
Photoelectric smoke detectorsPhotoelectric smoke detectors are best at detecting the large particles typical of smoky, smoldering fires but poor at detecting fast, flaming fires. Photoelectric units are less prone to false alarms from burnt food, so they may be a better fit in kitchen areas.
Which smoke alarm is better for kitchen?
photoelectric alarmsThese failing points are why photoelectric alarms are a better choice for areas like the kitchen. Instead of metal plates, photoelectric alarms use a beam of light aimed away from a sensor. Smoke can reflect the light, and if the reflected light hits the sensor, the alarm goes off.
Do you need a heat detector in the 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.

What type of alarm works best for very fast, fierce fires?
This type of alarm works best for very fast, fierce fires. Photoelectric smoke alarms operate using a light source and a photoelectric sensor. When smoke enters the optical chamber and interrupts the path of the light, the light is scattered about by the smoke particles and causes a sensor to activate the alarm.
How far away should smoke alarms be from cooking appliances?
Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimize false alarms when cooking.
How many different types of smoke alarms are there?
Although they are often lumped together as " smoke alarms ," there are actually three different types of smoke and fire alarms used in homes. Some actually detect heat and actual fire, some detect smoke, and some do both jobs.
What is a heat detector?
They feature a detecting component inside the unit that activates an alarm when it reaches a predetermined temperature. Heat detectors are sufficient for places where speed of detection isn't critical, or in small, confined spaces.

For ultimate protection against catastrophic fires in your kitchen and home, hook up hard wired, interconnected smoke detectors to your security system so you will be alerted of a fire whether you are present or away. If your home is not equipped with a security system, you can install a DIY autodialer system like the Sensaphone 400 Cottagesitter with smoke detector sensors to monitor your property 24/7. If there is an emergency, like a fire, the Sensaphone 400 will notify you immediately by phone.
What type of smoke detector is more responsive to fires that begin with a long period of smoldering?
Photoelectric Smoke Detectors – This type is more responsive to fires that begin with a long period of smoldering, such as a cigarette burning in a couch or bedding. Note that photoelectric smoke detector packages are labeled with a “p.”
What type of smoke detector is used to detect flaming fires?
Ionization Smoke Detectors – This type responds more quickly to flaming fires with smaller combustion particles, such as paper burning. It is generally less expensive. Note that ionization smoke detector packages are labeled with an “i.”
How does an ionization smoke detector work?
How they work: Ionization-type smoke detectors have a small amount of radioactive material between two electrically charged plates, which ionize the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.
How does a photoelectric alarm work?
How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm.
Why do you need a smoke detector?
Installing smoke detectors makes you feel safe from a possible fire. Staying aware of their correct placement and maintenance will ensure that no smoke goes undetected in your home.
What are the different types of smoke detectors?
Means of Detection: There are three kinds of smoke detectors: photoelectric, ionization, and a combination of the two, called a dual sensor. Photoelectric ones are better at picking up slow-building, smoldering fires, like one resulting from a lit cigarette.
How to prevent false alarms in kitchen?
In the kitchen, place the smoke detector away from the stove to prevent false alarms. If someone in your home is deaf or hard of hearing, consider a detector that also combines flashing lights with its alarm sound.
How far away should a smoke detector be from a stove?
With many homes having open floor plan designs, they may already have a smoke alarm located near a kitchen that may need to be replaced due to old age. [All smoke alarms should be replaced after 10 years.] However, placing a smoke alarm too close to cooking appliances, like a stove, could increase the likelihood of false alarms, such as those caused by burnt toast. That’s why we included the asterisk directing the consumer to the back highlighted yellow box stating that it should be installed at least 10 feet away from cooking devices.

Yet, surveys show three out of four homeowners do not know where to place smoke alarms. The location recommendation helps remind consumers of placement suggestions.
Where to put smoke alarms in California?
However the California State Fire Marshal says otherwise: “Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A Smoke Alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.” That’s a lot of detectors!
What is a smoke detector?
Smoke detectors are tuned to be looking for the dark sooty carbon byproducts of combustion. They do this by sensing extremely fine particles as they pass between an emitter and a sensor. The emitter/sensor combo can either be an infrared light source and a photocell or a small radioactive source and an electrical detector.
What does a smoke alarm do when it goes into prealarm mode?
When this happen, signal is sent from this sensor to other micro switching components of the smoke alarm to either go into prealarm mode (the smoke alarm tries to double check the cause of activation by flashing red indicator LED at faster intervals with pulse sound, based on the design) or going into full alarm.
What temperature should a heat detector be?
A 135 degree fixed temperature heat detector would do well. If your kitchen reaches 135 degrees, you’re probably in trouble. Don’t mount it right above the stove, oven or cook top though, just to be safe. In most places in the home I would use a rate-of-rise detector, which also trips if the temperature rises 15 degrees
Where should smoke alarms be installed in California?
However the California State Fire Marshal says otherwise: “Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A Smoke Alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or Smoke Alarms in the living rooms, dining rooms, bedrooms, kitchens
Does steam trip a photoelectric detector?
The water vapor in steam is mostly clears, easily allowing light to pass through and failing to trip most photo-electric detectors unless you have some pretty heavy steam. Light steam like you get from a shower or from home cooking may not be dense enough to trip the detector in an ionizing detector, but if you have some serious industrial grade steam (as in our basement example from earlier) you will get alarms and if you decide it can wait until your regular maintenance person comes into tomorrow instead of calling someone out to fix it immediately you will get some frustrated dispatchers too.
What happens when dust gets into a sensor?
Whenever particles like smoke, dust, vapour or steam gets into this chamber, there will be scattering of light rays which obstruct the view of the optical sensor.
