Typical applications

The E2639-O3 detector is intended for monitoring ozone in environments such as printing and photocopying centres, disinfection and sterilisation equipment, laser facilities, storage areas with ozone generators, and other enclosed spaces where O3 may accumulate. The device helps prevent health risks associated with exposure to this gas and contributes to ensuring the safety of both personnel and operations.

Ozone (O₃)

Ozone is a colourless gas with a characteristic sharp odour reminiscent of chlorine, which can be easily detected at higher concentrations. It is generated by electrical discharges, exposure to UV radiation, or as a by-product of laser printers, welding, and disinfection equipment. Even low concentrations of ozone can cause health problems such as eye irritation, coughing, headaches, or damage to the respiratory tract, while higher levels may lead to serious lung damage.

Smart communication – ideal for fire alarm systems

The E2639 detector combines the advantages of an autonomous safety element 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 without removing the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of a 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 everyone works only within their own part of the settings.
