E2639-CO2-50KN is a detector designed for monitoring high concentrations of carbon dioxide in the air. The device is equipped with a temperature-compensated sensor that ensures reliable detection and stable measurement, and it is housed in a wall-mounted enclosure with IP65 protection. The E2639 features three SPDT relays with a maximum load of 250 VAC 5 A. Two relays are used for so-called two-stage detection. The third relay indicates a sensor fault. Communication with higher-level systems is provided by an RS485 Modbus RTU digital interface, complemented by two 4–20 mA analogue outputs. In addition, the device includes four LEDs and an audible alarm, which immediately alert operators to any exceeded threshold directly at the installation site – without the need to monitor a remote control system.
The E2639-CO2 sensor is designed for monitoring carbon dioxide in industrial, commercial and public environments such as breweries, wine cellars and fermentation facilities, server rooms with CO2 fire suppression systems, restaurants and bars with draught dispensing equipment, dry ice storage areas, and other spaces where this gas may accumulate.
Carbon dioxide is a colourless, odourless gas that occurs naturally in the atmosphere and is also a by-product of a wide range of industrial processes such as fermentation, combustion and beverage production. Because it is denser than air, CO2 accumulates near the floor and in low-lying areas, making it an insidious hazard – its presence cannot be detected by human senses. At higher concentrations, it causes dizziness, unconsciousness and, in extreme cases, death by asphyxiation.
The E2639 detector combines the benefits of an autonomous safety device and an intelligent communication node. It is designed for seamless integration with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:
The E2639 is equipped with three M20 cable glands and a dual terminal block for Modbus RTU. The duplicated Modbus RTU terminals simplify and speed up bus wiring for connection to a higher-level system. No more inserting two conductors into a single terminal. Thanks to the M20 cable glands, all required outputs can be connected conveniently.
Factory settings:
Each detector package includes the manufacturer’s original calibration certificate in English, confirming the accuracy and correctness of measurement at the time of factory release.
