Typical applications

The E2639-VOC(C7H8) detector is intended for monitoring toluene in environments such as paint shops, printing works, chemical and pharmaceutical facilities, paint and thinner storage areas, vehicle repair workshops, and other enclosed spaces where volatile organic compounds may accumulate.

Toluene (C7H8)

Toluene is a volatile organic compound that readily evaporates into the air and can build up to dangerous levels in enclosed spaces. Although it has a characteristic odour, it cannot be relied upon as a warning sign, because the sense of smell quickly adapts with repeated exposure and stops detecting it. Exposure may lead to headaches, nausea, dizziness or impaired concentration, and at higher concentrations or with prolonged exposure there is a risk of serious damage to the nervous system, liver and kidneys.

Smart communication – ideal for fire alarm systems

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:

• Autonomy: 3× volt-free SPDT relays for direct control of equipment or safe system shutdown.
• Connectivity: Dual RS485 Modbus RTU interface for real-time digital export of measured data 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 features 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 your 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.
