X-Sense SC07-W wireless smoke and CO detector review

Carbon monoxide is responsible for over 400 deaths in the USA every year. On the other hand, over 3,000 people lose their lives to fires yearly.

It helps to have a system that can warn you in case of a fire outbreak or CO build-up in your home. The X-Sense SC07-W is one device that combines a smoke and carbon monoxide alarm to enhance your safety.

The concept of a combined smoke and carbon monoxide detector is to detect a fire or carbon monoxide gas as early as possible to give you and your family enough time to exit a building.

In both situations, time is of the essence. That is why the X-Sense SC07-W will alert you by beeping.

Even better, it comes as a network of 6 devices you can place strategically. When one goes off, it triggers the other 5. This makes it easier for all occupants in the home to be aware of the emergency.

How the X-Sense SC07-W detector works

The X-Sense SC07-W combination smoke and CO detector (2-in-1) has two crucial sensors:

  • Photoelectric
  • Electrochemical

The photoelectric detector uses a beam of light to detect the presence of smoke from fast-burning and smoldering fires.

When smoke particles float in the house and into the light beam, the light reflects off them and towards a small chamber, which sends an electronic signal to activate the alarm.

On the other hand, the electrochemical sensor uses electrodes submerged in chemical baths. They detect carbon monoxide leaks from faulty fuel-burning appliances.

When a home has any presence of carbon monoxide, the electrodes in the chemical baths sense changes in electrical currents.

If the levels are high, in this case, CO levels above 30 ppm, the changes in electrical currents will trigger the alarm. You can then find ways to ensure carbon monoxide dissipates from your home and fix the leakage.

This dual-sensor smoke alarm with a carbon monoxide detector will continuously monitor deadly threats in your home in a single device.

Features of the X-Sense SC07-W smoke and carbon monoxide detector

The X-Sense SC07-W smoke and carbon monoxide detector have several features that work together to detect smoke and high levels of carbon monoxide in a home.
