## Summary description

X-Sense CO03D-W Link+ is a battery operated carbon monoxide alarm with wireless interlink capability.

## Long description

X-Sense CO Sensor CO-3D-W Link+. The X-Sense CO03D-W Link+ is a battery-operated carbon monoxide (CO) alarm with wireless Link+ interconnect technology. It continuously monitors indoor air for CO using a Figaro electrochemical sensor and provides a local LCD readout of CO concentration. When linked with compatible X-Sense Link+ devices, up to 24 units form a wireless network so that if one unit detects hazardous CO levels all connected alarms sound simultaneously. The unit is powered by three replaceable 1.5 V AA alkaline batteries and meets EN 50291-1:2018 safety standards.
Advantages
The detector uses a high-precision Figaro electrochemical sensor that responds proportionally to CO concentration, enabling faster alarm at higher levels. Link+ wireless interconnect supports up to 24 devices for synchronized whole-home warning. A clear LCD shows real-time CO levels while tri‑colour LEDs (green, yellow, red) indicate status, battery and alarm conditions. The alarm sound level is ≥85 dB at 1 m. Replaceable AA batteries and a low-battery warning provide long-term, uninterrupted operation. Compact dimensions (110 x 110 x 37 mm) and included mounting accessories allow quick installation.
Suitable for
Homes and apartments
Multi-storey houses where several interconnected alarms are needed
Holiday homes and small rental properties
Any indoor space requiring continuous CO monitoring

How to use
Install the mounting bracket using the included screws or wall plugs and attach the alarm to the bracket. Insert three 1.5 V AA alkaline batteries and check the LCD and LED indicators to confirm power and readiness. Perform a test using the test/silence button to verify correct operation. To create a Link+ network, follow the manufacturer pairing procedure to add compatible X-Sense devices—when linked, an alarm on any unit will trigger all connected devices. If the unit alarms, evacuate the area immediately and follow local safety procedures.
Usage recommendations
Place CO alarms at least one on each level of the building and close to sleeping areas. Do not install directly above fuel-burning appliances or in locations subject to extreme temperatures or condensation. Test the alarm regularly and replace batteries when the low-battery indicator appears; replace the detector at the end of its 10-year service life.
