Gas detector DD-22 carbon monoxide, 30/60/150 ppm, p-p sensor, RS485

Carbon Monoxide Detector DD-22 – a reliable monitoring system

The DD-22 gas detector is an advanced device designed for continuous monitoring of carbon monoxide concentration in rooms. It reacts quickly and precisely to threats, informing about exceeding permissible norms with optical and acoustic alarms, and also transmitting data to a central control system. This is a key solution to ensure safety in public buildings, offices, hotels and other facilities where the risk of carbon monoxide occurrence is increased.

Functionality and application

DD-22 is designed to work with the GAZEX Digital Gas Detection System, offering reliable and stable operation thanks to the built-in microprocessor. The device is particularly useful in areas threatened by the emission of toxic gases, where regular monitoring is essential. Thanks to the replaceable sensor module, detector maintenance is simple and economical – sensor replacement extends the device's life and reduces operating costs.

Advantages of the DD-22 detector

• High measurement accuracy: p-p sensor provides accurate readings of carbon monoxide concentration in the range of 30/60/150 ppm.
• RS485 communication: Enables remote supervision, identification and diagnostics of the detector via the MODBUS RTU protocol. This allows integration with existing building automation systems and a central security management system.
• Configurable alarm thresholds: Standard three alarm thresholds (A1/A2/A3) allow you to adjust the detector's sensitivity to the specific conditions of a given facility.
• NO/NC contact outputs: Provide flexibility in connecting to various alarm and control systems.
• Built-in signaling: Both optical and acoustic alarm signaling informs about exceeding permissible gas concentrations. Acoustic signaling can be disabled using a jumper.
• Easy installation: Aesthetic housing (white standard) allows wall or Ø60mm installation box mounting. Removable screwless terminals facilitate the connection of shielded telecommunication cables.
• DETnet View configuration software: Enables easy configuration of detector settings and access to diagnostic data.
• Accredited calibration laboratory: All detectors are calibrated in their own GAZEX Calibration Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees their high accuracy and reliability of measurements.

The DD-22 detector is an investment in safety and comfort that will meet the expectations of both professional installers and end users. Reliability, ease of configuration and the ability to integrate with other systems make it an ideal solution for a wide range of applications.
