Rilevatore di monossido di carbonio wireless ATLO-CD21MF-RF con LCD e 433 MHz

The ATLO-CD21MF-RF stands out among carbon monoxide detectors by pairing a precise electrochemical sensor with a clear LCD and 433 MHz wireless connectivity, making it a natural fit for homes already using ATLO alarm systems or gateways. Unlike basic standalone units, this detector can send alerts to a central system, so you’re notified even if you’re not in the same room when the alarm triggers.

Highlights

• Electrochemical sensor for accurate CO detection with three alarm thresholds (50, 100, 300 ppm)
• Wireless 433 MHz communication up to 100 m in open field, compatible with ATLO systems
• LCD display for real-time CO concentration and status
• Loud ≥85 dB alarm at 1 m ensures you hear it even from another room
• Low battery and end-of-life warnings keep the unit reliable
• Flexible installation: wall-mounted or freestanding
• Certified to EN 50291-1:2018 for safety and performance

In daily use

Place the detector near bedrooms or in hallways, and it continuously monitors the air. The LCD shows current CO levels, so you can check at a glance. If CO reaches dangerous levels, the alarm sounds and the wireless signal alerts your ATLO gateway, which can trigger other sirens or notifications. The test button lets you verify functionality monthly, and the low battery warning ensures you replace batteries before they die. With a sensor lifespan of 7 years, you won’t need to replace the unit often.
