Typical applications

The E2639-CO2 detector is intended 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, or other spaces where this gas may accumulate. 

Carbon dioxide (CO₂)

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 the senses. At higher concentrations, it causes dizziness, unconsciousness and, in extreme cases, death by asphyxiation.

Smart communication – ideal for fire alarm systems

The E2639 detector combines the advantages 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:

• Autonomy: 3× volt-free SPDT relays for direct control of equipment or safe system shutdown.
• Connectivity: Dual RS485 Modbus RTU interface for digital export of measured data in real time to a higher-level system (BMS).
• Control: 2× 4–20 mA analogue outputs intended for precise control of the ventilation frequency inverter.

WiFi calibration from any smart device

Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – with no tools and no need to remove the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of your phone or tablet, with no need to download any app. The interface is password-protected with separate access levels for end users and integrators, so each user works only within their own section of the settings.
