Codesec CO401K Carbon Monoxide Detector With Relay

The Codesec CO401K is a high-precision conventional carbon monoxide detector manufactured by Codesec for underground parking garages, boiler rooms, industrial facilities, and commercial buildings. Utilizing a high-stability electrochemical sensing cell, the detector accurately measures toxic CO gas concentrations in parts per million (PPM). Driven by an internal microprocessor running intelligent signal processing algorithms, the device provides rapid warning upon detecting elevated CO levels while minimizing false activations caused by other airborne gases. Operating on a 12V DC or 24V DC power supply, the unit features an integrated Form C relay output to directly drive extraction fans, shut-off valves, or external control modules, along with clear visual LED status verification, an onboard piezoelectric buzzer for local acoustic warning, and compliance with EN 50545-1 standards.
