Typical applications

The E2639-N₂O detector is intended for monitoring nitrous oxide in environments such as healthcare facilities, dental surgeries, operating theatres, chemical laboratories, food processing plants, and other enclosed spaces where N₂O may accumulate. The device helps prevent health risks associated with exposure to this gas and contributes to the safety of both personnel and operations.

Nitrous oxide (N₂O)

Nitrous oxide is a colourless gas with a faintly sweet odour, the presence of which in air cannot be reliably detected by the senses at normal concentrations. In enclosed spaces, it can accumulate to dangerous concentrations and, at higher levels, has a narcotic effect on the central nervous system. Exposure to higher concentrations of nitrous oxide may cause dizziness, nausea, disorientation, or loss of consciousness, and prolonged exposure may result in damage to the nervous system, impaired blood formation due to inhibition of vitamin B₁₂, and adverse effects on reproductive health.

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 a phone or tablet, with no need to download any application. The interface is password-protected with separate access levels for end users and integrators, so everyone works only within their own section of the settings.
