X-Sense XC04-WX Smart Carbon Monoxide Detector Review

The XC04-WX carbon monoxide alarm is another compact, efficient, and functional CO detector from X-Sense.

When I got this device, the first thing that I realized was how light it is compared to the SC07 carbon monoxide and smoke detector. But is it any better? In this review, I will share my experience with the X-sense XC04-WX.

Overview

The X-Sense XC04-WX is a smart carbon monoxide alarm. It uses a wireless connection and an app to inform you about the carbon monoxide levels in your home. When it detects high CO levels, you get a push notification in your app to take action.

Important to note that although it detects carbon monoxide in your home, it does not detect smoke. Therefore, you must buy a separate smoke detector that works alongside the X-Sense XC04-WX Smart Carbon Monoxide Detector.

But if your main concern is to detect CO levels and keep your family safe from its effects, then you will find the XC04-WX quite useful.

X-Sense XC04-WX: Pros and Cons

The X-Sense XC04-WX Smart Carbon Monoxide Detector may be all you need to protect your home from dangerous CO levels. But like many other devices, it has several pros and cons.

Pros

  • Offers a wide range of carbon monoxide detection from 30 to 999 ppm.
  • Bright LCD that is easy to read.
  • Compact design that allows you to install it anywhere.
  • It gives you real-time push notifications via an app.
  • Updates you on potential CO dangers since the last reset.
  • It provides 24/7 fire dispatch when needed.
  • Its sensor has a 10-year lifespan.
  • Easy to set up.
  • Built from tough, long-lasting material.
  • Has a battery level indicator on the LCD screen.

The device also has a loud alarm that produces a noise of up to 85 dB.

Cons

  • It doesn’t have a rechargeable battery. You’ll have to replace it once it wears out.
  • It does not offer smoke detection.
  • It requires a monthly payment for the dispatch service.

Unlike other X-Sense products, the X-Sense XC04-WX smoke detector does not show temperature values.

How does it work?

The X-Sense XC04-WX is an electrochemical smart carbon monoxide detector with three electrodes.

It uses a gel (a non-metallic liquid electrolyte that conducts electricity) to detect carbon monoxide and measure a chemical reaction within its sensors (electrodes).

When the chemical reaction reaches a specific measurement, or the electrodes change in electrical current, the sensor creates an electrical output relative to the CO level produced and sounds off the alarm.

Packaging

The XC04-WX comes in a compact package that contains the following:

  • 1 carbon monoxide detector.
  • A user manual.
  • 2 mounting screws.
  • A drill hole spacing template.
  • 2 warning stickers
  • 2 anchor plugs
  • 1 battery

The total weight of the item is about 4.6 ounces.

Features of the X-Sense XC04-WX Smart Carbon Monoxide Detector?

The X-Sense XC04-WX Smart CO detector has many features that allow it to detect carbon monoxide levels in your home. They include:

  • Wi-Fi connectivity: You can connect it to the X-Sense Home Security app via a 2.4 GHz Wi-Fi network.
  • LCD display: The LCD helps you read the levels of CO in your home. It also has red, green, or yellow lights to show the alarm’s status.
  • Silence/Test button: The silence button allows you to silence false alarms and test the unit’s functionality.
  • CO concentration memory: It has a peak carbon monoxide concentration memory to show you the highest CO concentration since the last time you reset it.
  • Figaro CO sensor: The Figaro CO sensor works by accurately monitoring carbon monoxide levels in the house, ensuring protection for ten years.
  • Battery: The WXC04-WX has a replaceable battery. You can monitor its status through the battery level indicator on the LCD screen.

How does the X-Sense XC04-WX compare with other X-Sense carbon monoxide detectors?

The X-Sense XC04-WX is just about the size of a pen in length.

Just like the XC01-R, the XC04-WX uses electrochemical sensors to detect CO levels in a room. But the difference is that the XC01-R does not support the home security app. This is inconvenient since you cannot get a notification when the device detects CO levels while you are away.

If your intention is to detect smoke and fire other than CO, consider getting the XS01-WT. Note that you cannot use it to detect CO levels. However, it makes more sense when you use it together with the XC04-WX to detect smoke, fire, or CO instantly.

The idea of having two separate devices might not be ideal for all. And that’s where the SC07-W comes in. It combines both smoke and carbon monoxide detectors. The only disadvantage is it is bulky compared to the XC04-WX.

Finally, there is the SD20-W which only detects fire and smoke but not carbon monoxide. Therefore, you may need the XC04-WX and SD20-W to detect fire, smoke, and CO levels in your room.

How to install the X-Sense XC04-WX Smart Carbon Monoxide Detector

Before you do anything, read the instruction manual that comes with the X-Sense XC04-WX smoke detector. Next, confirm that you have the alarm unit, two screws, and two anchor plugs.

Here are the wall mounting installation steps.

  • Remove the indication sticker from the packaging.
  • You will see hole locations on the sticker.
  • Draw two screw holes based on the layout and size of the mounting holes on the back of the unit.
  • Drill the holes to about 1.18 inches deep.
  • The distance between the centre of the two holes should be 2.9 inches.
  • Mount and lock the alarm into place.

At this point, you can test the device by pressing the Test button.

Note: You do not have to mount the alarm on a wall. Instead, you can use the two stands built into the design to position it on a flat surface like a shelf.

Understand that the best place to install the carbon monoxide alarm is in any room containing a fuel appliance. However, you can install it in any room to help keep its occupants safe and aware of CO levels.

How to connect the XC04-WX Carbon Monoxide Detector to Wi-Fi

How much does it cost?

The XC04-WX is one of the market’s most affordable carbon monoxide detectors.

You can buy it from the official X-Sense store for $39.99 or from Amazon.

Is the XC04-WX worth your money?

Absolutely. While it is easy to ignore having a CO detector, these tiny devices can save your life, loved ones, and property.

I have tested the XC04-WX and noticed how quickly it responds to rising CO levels. Its alarm is loud enough, and notifications are prompt. At its price, it is a must-have for every homeowner.

However, if you need something that can detect smoke, fire, and CO, consider the options we mentioned above.
