Types of Smoke Detectors

There are several types of smoke detectors available on the market. There are also various features that can differ between the different types of smoke alarms. First, let’s look at the technology inside a smoke detector. There are two ways that smoke alarms detect smoke. There are photoelectric smoke detectors, and there are ionization smoke detectors.

Photoelectric Smoke Alarms

Photoelectric smoke detectors use light to detect the presence of smoke. Inside a photoelectric smoke alarm, there is a light source. That light source shines towards a light-sensing chamber. When smoke particles enter the chamber, the light is scattered. That triggers the smoke alarm. Photoelectric smoke detectors are very good for detecting smoldering fires. Fires where there is smoke, but not a lot of flames. Photoelectric smoke detectors are less prone to false alarms than ionization smoke alarms. They can, though, be triggered by dust particles.

Ionization Smoke Alarms

Ionization sensors contain a small amount of radioactive material. Don’t worry, it’s not enough to be harmful. The material sits between two electrically charged plates, which causes ionization to occur. When smoke particles enter the system, it disrupts the ionization. That triggers the smoke alarm. Ionization smoke detectors are good for detecting smoke from fast-burning fires with flames. They can, though, be triggered by burning food, and by steam.

Dual Sensor Smoke Alarms

Dual sensor smoke alarms contain both photoelectric smoke detectors and ionization smoke detectors. Some dual sensor smoke alarms will sound when only one of the detectors is triggered. Some will only sound if both sensors are triggered. Dual sensor smoke detectors are more sensitive. They will detect both smoldering and fast-burning fires. They are also more prone to false alarms.

What Type of Smoke Alarm is Recommended?

The National Fire Protection Association (NFPA) recommends that you install a mixture of the two types of smoke detectors. That will provide the most protection. They also recommend that you buy interconnected smoke alarms. Ideally, you should have smoke alarms on every level of the home, including the basement. There should also be a smoke alarm in every bedroom, and outside each sleeping area. Of the two types of smoke alarms, the best smoke detector to buy is a photoelectric detector. They detect smoke from smoldering fires faster. If you can, you should then back those up with some ionization smoke detectors.

Things to Consider When Buying a Smoke Detector

As well as the choice of type of smoke detector, there are also other features that will help you decide on the best smoke detector for your home. Here’s a rundown of the various design features of smoke alarms that you need to think about.

Interconnected Smoke Alarms

Some of the best smoke detectors and carbon monoxide alarms can be linked together. When one alarm is triggered in an interlinked smoke detector setup, all the alarms in the home will sound. This is far safer, especially in a large home. In a small apartment, though, interlinked smoke alarms may not be necessary.

A Silence, or Mute, Button

Even the best smoke detectors may trigger false alarms. It is important, then, that the smoke alarm you choose has a mute button. The silence button will temporarily silence the alarm, but the alarm will still be active. Most modern smoke alarms do have a silence button, but it’s worth checking to make sure.

Power Supply

There are both hard-wired smoke detectors and battery powered smoke alarms available. Wired smoke alarms are considered the be better, but they do require installation. Battery powered smoke detectors are available in two types. Some are sealed units with ten-year batteries in. Some use regular, replaceable batteries.

Smoke Alarms with Lights

If you have impaired hearing, a smoke alarm that has a flashing warning light would be the best smoke detector for you. Some alarms also have a safety light to provide illumination in an emergency.

Best Smoke Detectors – In-Depth Reviews

Below, you will find our detailed reviews of six of the best smoke detectors. The best smoke detector for your home will depend on the points we discussed above. And, of course, your budget. At the top end of the rage there are smart smoke detectors, like the Nest smoke alarm. There are also some very good quality budget smoke alarms available. We hope that these best smoke detector reviews give you a good idea of the types of smoke alarms that are available.

1. First Alert Battery Combination Smoke and Carbon Monoxide Detector

First Alert Smoke and Carbon Monoxide Detector, Best Battery Smoke Detector, Best Smoke Detector Reviews, Smoke Detector, Smoke Alarm, Fire AlarmThe First Alert smoke alarm is a battery powered combined smoke and carbon monoxide detector. The photoelectric sensor inside the unit will detect smoke from smoldering fires. The carbon monoxide detector will provide protection against carbon monoxide leaks from things like faulty heating appliances.

This First Alert smoke detector is battery operated. That makes installation easy, because there is no wiring to do. It does, though, mean that the batteries will need replacing once a year.

The smoke alarm is powered by AA batteries. Batteries are included.

There are two variations of the First Alert Battery Combination Smoke and Carbon Monoxide Detector. The First Alert SCO5CN smoke alarm sounds an 85-decibel siren when the device is triggered. The First Alert SCO7CN smoke alarm has the siren, plus a voice alert. The voice alert will tell you whether it is a smoke or carbon monoxide that has triggered the alarm. It will also tell you the location of the alarm. The alarm is available in packs of 1, 3 or 4.

The First Alert Battery Combination Smoke and Carbon Monoxide Detector is a good-quality smoke detector form a well-respected supplier. The photoelectric sensor will detect the smoke from a smoldering fire, so you get more time to take appropriate action. The carbon monoxide detector will protect you against carbon monoxide poisoning. The voice alert version of the smoke detector will tell you what room the arm is sounding in. So, it gets our vote for best smoke detector in the battery-operated class!

2. Nest Protect Smoke & Carbon Monoxide Alarm

Nest Protect Smoke & Carbon Monoxide Alarm, Best Smart Smoke Detector, Best Smoke Detector Reviews, Smoke Detector, Smoke Alarm, Fire AlarmIt’s not an exaggeration to say the Nest Smoke & Carbon Monoxide Alarm is the next generation in smoke alarms. It’s a combined smoke and carbon monoxide detector. It works with your phone, and your other Nest devices.

The Nest Protect Smoke & Carbon Monoxide Alarm is a smart smoke detector. It will alert you the presence of smoke or carbon monoxide through a siren, a voice announcement, and an alert on your phone.

Another big advantage for those of us who are not very tall, is that you can silence the Nest smoke alarm from your phone. So, no more balancing on a chair when you get a false alarm!

The fire detection sensors of the Nest Smoke & Carbon Monoxide Alarm are also way ahead of most other best smoke detectors. There’s a dual smoke detection system that will sense smoke from smoldering fires and fully established fires. There’s even a humidity sensor so that the alarm can distinguish smoke from steam. The alarm is available as a battery unit only, or a hard-wired with battery backup unit.

The Nest Protect Smoke & Carbon Monoxide Alarm is the best smoke detector on the market. So, is there anything wrong with it? Well, unfortunately, the Nest smoke alarm is four times as expensive as some other models. That’s a big difference if you want to put a smoke alarm in every room of the home.
