Asenware AW-D125C Conventional Carbon Monoxide (CO) Detector

AW-D125C is a wall-mounted conventional CO gas detector that continuously measures carbon monoxide concentration in ambient air in the range of 0-999 ppm. In boiler rooms, enclosed parking areas, generator rooms and spaces with flued appliances, it provides early warning of CO buildup from incomplete combustion; the LCD display shows instantaneous ppm value, power supply, fault and alarm conditions are monitored via separate LEDs. Alarm response times are tiered according to concentration: at 50 ppm within 60-90 minutes, at 100 ppm within 10-40 minutes, at 300 ppm within 3 minutes. The device has four wires; 20-28 V DC power supply is run separately, connection to conventional panel is via relay contact, not powered from the panel line. It is documented within EN 50291-1:2018 scope as a CO gas alarm and does not substitute for a fire detection detector; sensor lifespan is 10 years and the detector must be replaced when this period expires.
