The Kidde Smoke Alarm Dual Sensor Detector has both photoelectric and ionization sensors to protect you from smoldering and flaming fires. The First Alert Hardwire Photoelectric and Ionization Smoke Alarm is an excellent detector that relies on hardwiring and can detect the two main types of fires.

Moreover, are dual sensor smoke alarms better?

DualSensor Smoke Detectors combine ionization and photoelectric technology to detect both flaming and smoldering fires, offering you the best protection and saving you the hassle of installing two separate smoke detectors. But you may still need to install carbon monoxide detectors, if appropriate for your home.

Beside above, what is the best smoke and carbon monoxide detector? Our Top Picks

  • Best Overall: First Alert 3120B Hardwire Photoelectric & Ionization Smoke Alarm at Amazon.
  • Best Smart: Nest Protect Wired Smoke and Carbon Monoxide Detector at Home Depot.
  • Best Basic: First Alert Dual-Sensor Smoke and Fire Alarm at Amazon.

Simply so, what are dual sensor smoke alarms?

Dual Sensors Detect Two Kinds of Fire The photoelectric sensor detects smoldering fires from objects like cigarettes burning on furniture or in trash cans, while the ionization sensor detects fast-flaming fires like erupting kitchen grease fires or combustibles.

Are hard wired smoke detectors better?

Battery-powered smoke alarms are easier to install. With a simple replacement of the batteries, they'll be operational once again—however, you will have to replace batteries often since this is their only power source. Hardwired smoke alarms must be connected to your home's power supply.

Related Question Answers

Are ionization smoke detectors banned?

Currently, ionization-type smoke detectors are banned in three states: Massachusetts, Iowa, and Vermont. However, elsewhere they are the dominant type of smoke detector, due to their low price.

What is the best brand of smoke alarms?

Here are the best smoke detectors you can buy:
  • Best smoke detector overall: First Alert Smoke and Carbon Monoxide Alarm.
  • Best hardwired smoke detector: Kidde Smoke Alarm Dual Sensor.
  • Best dual-sensor smoke detector: First Alert Photoelectric and Ionization Smoke Alarm.

Why do smoke alarms randomly go off?

Dust can reflect the light particles, similar to smoke, which gives you a false fire alarm. To clean, simply remove the outer casing. Leave a careful amount of space between the smoke detector and bug spray. Keep in mind that harsh chemicals can also cause smoke detectors to go off.

What is the best 9v battery for smoke detector?

These 3 9V batteries are the BEST for smoke detectors
  • EN22 Energizer Industrial Alkaline 9V Battery.
  • 1222 Eveready 1.5V Super Heavy Duty 9V Battery.
  • LA522 Energizer 9V Advanced Lithium Battery.

What causes a smoke detector to false alarm?

What can cause smoke alarms to go off repeatedly?
  1. Smoke detector placement. It doesn't take a lot of smoke to trigger the alarm.
  2. Overcooked food.
  3. Steam or high humidity.
  4. Pesky insects.
  5. A buildup of dust.
  6. Strong chemicals nearby.
  7. The batteries need to be changed.

Can you interconnect different brands of smoke detectors?

When there is an actual alarm, the unit that detects the smoke triggers all the others to sound an alarm. Different manufactures use different signalling schemes for this common wire. Other units may or may not work together, or may mix up a smoke alarm versus a carbon monoxide alarm, so don't mix them!

How can you tell the difference between photoelectric and ionization smoke detectors?

When smoke particles enter the chamber, the conductivity of the chamber air will decrease. When this reduction in conductivity is reduced to a predetermined level, the alarm is set off. Photoelectric smoke alarms are fairly uncommon today. They are quicker at sensing smoldering fires than Ionization smoke alarms.

Can I mix Nest Protect with other smoke detectors?

Wireless interconnect lets you add additional alarms without adding expensive wiring. Both Nest Protect (Battery) and Nest Protect (Wired 120V or 230V) are fully compatible with each other so you can mix battery and wired Nest Protects in your home.

What is dual sensor?

Dual Sensor Thermometers are typically used for environmental monitoring. They are ideal for comparing two environments simultaneously. The units have one internal sensor that can track the immediate surrounding environment.

Do ionization smoke alarms detect carbon monoxide?

Carbon Monoxide Detector with Ionization Smoke Alarm

Just like the photoelectric combo unit, these detectors will detect CO2 as well as smoke. Ionization smoke alarms are good at detecting kitchen fires or fast flaming fires. The drawback to these units is that they are prone to false alarms.

How do I choose a smoke detector?

Know your types of smoke alarms
  1. Install smoke alarms on every floor of your home, in hallways, inside bedrooms and outside of sleeping areas.
  2. Replace smoke alarms every 10 years.
  3. Test your smoke alarm per manufacturer's instructions and replace the batteries as needed.

How many types of smoke detectors are there?

three types

Where do you put ionization and photoelectric smoke detectors?

According to the NFPA, smoke alarms should be placed in every bedroom, outside each sleeping area and on every level of your home. In addition, industry experts recommend having both photoelectric and ionization alarms for optimal protection against flaming and smoldering fires.

How does an ionisation smoke detector work?

How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes 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.

What temperature do heat alarms go off?

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 linked?

By connecting multiple Wireless Interconnected alarms, you can be alerted to danger on the other side of your house before the smoke from that area reaches you. When one alarm sounds, all connected alarms in the system will sound simultaneously. Earlier notification of danger means you can escape sooner.

How long do smoke and CO detectors last?

Most smoke alarms have a lifespan of eight to 10 years, and again, replace the batteries every year. A smoke detector with a lithium battery or a hard-wired smoke detector can last 10 years, at which time you would just replace the whole unit. Carbon monoxide detectors last between five and seven years.

What is the difference between smoke detector and carbon monoxide?

Smoke detectors alert you to the presence of smoke and possibly fire in your home. Carbon monoxide detectors alert you to dangerous levels of carbon monoxide gas. A number of household appliances emit carbon monoxide, including gas stoves or ovens, water heaters and space heaters.
