X-Sense vs First Alert: A Complete Comparison of The Two Best Smoke Detectors

CO Levels Detection

The X-sense smoke detector is a smoke detector with an LCD screen that displays CO readings. It is BS EN 50291-2 certified, has a ten-year lifespan, and comes with a warranty of 10 years or 100,000 hours on the battery.

The First Alert is one of the best smoke detectors to buy with its high performance and good value for money but it does not come with a display to show CO levels as at the time of this post

Smoke detectors are a must-have in every home. They detect smoke and fire, giving you time to evacuate and save yourself and your family. But did you know that many smoke detectors also detect carbon monoxide (CO)?

CO is a poisonous gas that can kill quickly, so it’s important to have a detector that can warn you of high levels of CO in your home.

If you’re looking for a top-of-the-line smoke detector with CO detection capabilities, look no further than the X-sense.

LCD Display

Smoke detectors with LCD displays are becoming more popular. This is because they offer a lot of advantages over traditional smoke detectors. The X-Sense is a reasonably priced carbon monoxide detector that has a 10 year battery life and an LCD display that shows the CO levels in ppm. The First Alert CO detector does not have an LCD display.

Audible Alarm Alert

Smoke detectors are an important part of any home safety plan, as they provide an audible alarm alert in the event of a fire. There are many different smoke detectors on the market, but two of the best are the X-Sense and First Alert smoke detectors.

The X-Sense detector is a cheap upgrade that gives you smart functions without having to replace your existing detector. This X-sense dual-sensing detector alerts homeowners to fire and carbon monoxide hazards in the home through its LCD and Loud alarm horn more than the First alert smoke detectors.

The X-sense device is great for homeowners who want an easy-to-read detector with no complicated installation requirement.


Both models of x-sense and first alert carbon monoxide and smoke detectors are very strong and durable. They will last for a long time without any problems.

Battery Life

Smoke detectors are a must-have in every home. While both the X-Sense and First Alert models are great options, there are some key differences between them. The most significant difference is battery life:

X-Sense’s batteries last 40 days on a full charge, while the First Alert model’s batteries only last for a few days. This means that the X-Sense is a better value for money in the long run. Additionally, both models have an added pathway light that makes it easier to see your way around in the dark.


First Alert is more expensive than X-Sense. Both offer additional features that are not available on other smoke detectors.


When it comes to warranties, the X-Sense smoke detector has the advantage. It has a longer warranty period of 10 years, while the First Alert has a 7-year warranty.

X-Sense vs First Alert: Which is the Best Smart Smoke Alarm Detector?

There are a lot of different factors you need to consider when choosing a smoke alarm detector. Do you want one that integrates with other devices? One with long battery life? One that is a photoelectric or dual sensor?

First Alert and X-Sense are two of the most popular brands of smoke detectors on the market today. They both have pros and cons in different categories, so it can be hard to decide which one is best for you.

Here at our company, we recommend the X-Sense 10-Year Battery Smoke and Carbon Monoxide Alarm with Display, Dual Sensor Smoke CO Alarm. It has a long battery life, can integrate with up to 24 other devices, and comes at a very affordable price. Plus, it uses photoelectric sensors which are more effective than single-sensor alarms at detecting fires.

How to Choose the Best Smoke and Carbon Monoxide Detectors/Sensor For Your Home

When it comes to choosing the best smoke and carbon monoxide detectors for your home, there are a few things you need to take into account. The most important factor is whether the detector sensor meets the safety standards of Underwriters Laboratories (UL) or the Canadian Standards Association (CSA).

Another important consideration is how often you want to be alerted of high levels of CO in your home. Most detectors offer a peak-level feature that determines the highest amount of CO present in the room and alerts you accordingly.

However, some detectors only sound an alarm once the peak level has been reached, so it’s important to read through the features carefully before making your purchase.

Additionally, consider how long you want your smoke and carbon monoxide detector to last before needing replacement batteries.

Many modern detectors come with 10-year battery life. And finally, if you’re looking for real-time alerting capabilities, make sure whichever device you choose offers this function.


What is the main Difference Between X-Sense and First Alert Smoke and Carbon Monoxide Alarm Detectors?

The X-Sense is a reasonably priced carbon monoxide detector that has a 10-year battery life and an LCD display that shows the CO levels in ppm. The First Alert CO detector does not have an LCD display.

Are First Alert and Kidde the Same?

Kidde and first alert are two different companies. Kidde is a US-based manufacturer and has been developing safety products for over 100 years. First Alert is a Canadian company that was founded in 1964.

The two companies produce different types of smoke detectors. Kidde has developed new technologies to compete in the IoT market and attract customers with smart homes. The new TruSense alarms are more affordable than other traditional smoke detectors, and they come with a RemoteLync Monitor that sends a notification when the alarm is sounded from any regular smoke detector, regardless of whether it uses an ionization sensor or not.

First Alert produces traditional smoke detectors with an ionization sensor and a circular LED light.

Are First Alert Smoke Detectors Interchangeable?

Yes, First Alert smoke detectors are interchangeable. The detectors have a range of more than 820 feet each and are all lightweight at 0 pounds, perfect for small or large spaces. The dimensions are 3″ x 3″ x 1.9″.

The X-Sense Wireless Interconnected smoke detectors take up less space but still meet UL standards. Additionally, the red alert lights are visible and easy to see even in a dark room. The Nest Protect has a “silence button” that also functions as an alert light.

Is X-Sense a Good Smoke Alarm?

Yes, X-sense of a good smoke alarm detector for homes. the First Alert brand has been around for a long time, but that doesn’t mean it’s the best choice. In fact, there are many reasons why you should consider X-Sense over First Alert.

The X-Sense SD01 is a smoke detector that uses an extra bright LED to help lead you to safety. The X-Sense SD01 will fit under your existing carbon monoxide detector, so no need for a new device. The X-Sense SD01 has a solid feel and is easy to install.

The LED light automatically activates when the alarm is activated, and it can help with seeing dark rooms. The X-Sense SD01 will be especially valuable to people living in the dark hours of the evening.

What Is Carbon Monoxide Poisoning?

Carbon monoxide (CO) is a colorless, odorless gas that can be fatal if not detected early. It’s emitted from appliances like boilers and water heaters when the fuel source isn’t burned properly, and it can also enter your home from the car’s engine while it is running.

Carbon monoxide enters the bloodstream and prevents red blood cells from carrying oxygen. Symptoms of carbon monoxide poisoning include dizziness, shortness of breath, blurred vision, and confusion. A carbon monoxide detector can detect high levels of CO in your home and alert you when this occurs.

Is X-Sense a Reliable Brand?

Yes, X-sense is a reliable smart smoke and carbon monoxide detector. Smoke detectors that use ionization and photoelectric technology are more reliable than those with basic sensors. For this reason, we recommend the X-Sense smoke detector.

Despite a slight delay, the X-Sense smoke detector is still reliable. In fact, its patented design makes it one of the most sensitive smoke detectors on the market today.
