X-Sense CO sensor CO-3D-W Link+.

The X-Sense CO03D-W Link+ is an advanced wireless carbon monoxide sensor that offers the highest level of protection against the dangerous and odorless gas carbon monoxide (CO). With its wireless connectivity feature, this sensor creates a home security network that allows it to sync with other X-Sense Link+ alarms, meaning that when one sensor detects danger, all other devices on the network immediately sound an alarm. This advanced feature gives you the highest level of protection and ensures that everyone in the house is immediately alerted to the threat, no matter where they are.

Wireless network for complete protection

The CO03D-W detector uses Link+ wireless technology, which allows up to 24 devices to be connected to a single network, making it ideal for large homes or multi-story buildings. When one device detects the presence of carbon monoxide, all other alarms in the network are immediately triggered, alerting the entire family to the danger. With this solution, all household members can be confident that they are protected, even if they are far from the place where the danger is detected.

Figaro precision CO2 sensor

The X-Sense CO03D-W sensor is equipped with Figaro's state-of-the-art electrochemical sensor, which provides reliable and accurate carbon monoxide detection. The sensor responds to different CO concentrations depending on their level and triggers an alarm faster in the event of a greater threat, enabling faster rescue. For example, at a concentration of 30 ppm, the alarm is triggered after 120 minutes, and at a concentration of 300 ppm after just 3 minutes.

LCD display and LED indication

The easy-to-read LCD display allows you to monitor the CO concentration level in the room in real time, allowing you to monitor the situation at all times. The three-color LED indicators – green, yellow and red – provide additional information on the device’s status, such as readiness for operation, low battery and alarm signal. The loud audible alarm ≥85 dB at a distance of 1 meter ensures that you will not miss the signal, even in noisy environments.

Replaceable batteries and low power warning

The sensor is powered by three easily replaceable AA alkaline batteries, allowing for long-lasting use. A built-in low battery warning system ensures that you are notified when the batteries need to be replaced, ensuring the sensor continues to function smoothly.

Test and mute function

The X-Sense CO03D-W is equipped with a test/silence button that allows you to easily test the sensor and silence the alarm if necessary. Regular testing of the alarm is essential to ensure its proper operation. If a false alarm is detected, the beep can be silenced for up to 9 minutes, eliminating the need to immediately dismantle the unit.

Compact design and easy installation

The X-Sense CO03D-W carbon monoxide detector has a modern and compact design, making it a discreet fit into any interior. Its compact size (110 x 110 x 37 mm) and lightweight design make installation quick and easy thanks to the included mounting hardware.
