E2639-O3 is a detector designed for monitoring high concentrations of ozone 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 an exceeded set limit directly at the installation site – without the need to monitor a remote control system.
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 is a colourless gas with a characteristic sharp smell reminiscent of chlorine, which can be easily detected at higher concentrations. It is generated by electrical discharges, 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.
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 (FAS) 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 help 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 original manufacturer's calibration certificate in English, confirming the accuracy and correctness of measurement at the time it leaves the factory.
