X-Sense CO Alarm Detector CO03D
Product description
If you want early warning of carbon monoxide in your home, the X-Sense Carbon Monoxide Alarm Detector CO03D is built for fast, accurate detection, with clear visual feedback and a loud audible alert. This battery operated CO alarm detector is designed to run reliably for day and night, including during power outages, while showing current readings on its LCD display. 🔔
With its 10 year sensor life, you can plan around long term protection rather than frequent replacements. It uses an advanced Figaro electrochemical CO sensor and a high performance ST chipset to help detect concentration levels promptly and to minimise false alarms, so you can react sooner when it matters. 🏠

Key features


The detector focuses specifically on carbon monoxide, often described as an invisible, deadly gas, and it is intended to provide an immediate warning when CO levels reach alarm thresholds. The alarm combines an 85 dB loud alarm with a rapidly flashing red LED indicator, giving you audible and visual cues together. The LED indicators are designed to avoid disturbing your sleep during normal working status, which helps if you place it in a bedroom or hallway where it will be left running continuously.

A large LCD display helps you keep track of what is going on. It shows the battery life and the real time CO level based on the surrounding air, with measurement updates taken every 10 seconds. This can be useful when you want reassurance that the unit is actively monitoring, rather than only relying on the sound of the alarm.
For flexibility in where you can fit it, the unit is battery powered and does not require wiring or a connection to a wall outlet. It comes with screws and anchor plugs to support quick installation, which is a practical benefit if you are updating existing safety setups or adding protection in another room. 🛠️



The essentials
Long term safety planning is a big part of why this model is made as a 10 year alarm with 24/7 protection. It is powered by 3 replaceable 1.5 V AA batteries, and the sensor life is stated as 10 years, so the unit is built to stay in service for a long period. Even if the power goes out, a battery operated CO alarm helps maintain coverage, which is especially relevant in homes where outages happen at inconvenient times.

There are also built in alerts for maintenance. A low battery alert informs you when you need to change the batteries, while an end of life warning lets you know when it is time to replace the unit itself. That approach helps avoid the common problem of forgetting about safety device upkeep until an alarm goes off.


A key detail to bear in mind is that it detects carbon monoxide only, not carbon dioxide. If your goal is monitoring for CO2, this device is not the right choice.
