ABUS COWM370 Carbon Monoxide Detector, Battery-Powered, Electrochemical Sensor, 85 dB Alarm, EN 50291-1 Certified, White

The ABUS COWM370 uses an electrochemical sensor to detect carbon monoxide with precision, triggering an 85 dB alarm at 3 meters when dangerous levels are present. Certified to EN 50291-1:2018, this battery-operated detector provides reliable protection for bedrooms, living areas, and hallways.

Overview

Carbon monoxide is a silent, odourless threat. The ABUS COWM370 is engineered to respond quickly to CO accumulation, with alarm thresholds that activate within 60–90 minutes at 50 ppm, 10–40 minutes at 100 ppm, and within 3 minutes at 300 ppm. Its electrochemical sensor offers stable performance over a 7-year lifespan, while three AA alkaline batteries deliver approximately 3 years of operation. The detector is designed for wall or ceiling mounting and features a test/mute button for regular function checks.
