Gas detector DG-22/NL/w carbon monoxide, 20/100 ppm(s15), p-p sensor, for installation in ventilation duct DG-22/NL/W

Carbon Monoxide Detector for Fire and Gas Alarm Systems

The DG-22/NL/W gas detector is designed for continuous monitoring of carbon monoxide (CO) concentration in the air. Thanks to the use of a semiconductor sensor, the device provides fast and reliable detection of this colorless and dangerous gas. It is a key element of safety systems in places where there is a risk of CO formation, such as boiler rooms, garages, rooms with solid fuel stoves, or in ventilation systems.

Construction and application

The DG-22/NL/W detector is designed for mounting on ventilation ducts, which allows for effective monitoring of the air throughout the system. Its compact dimensions (110 x 140 x 55 mm) make it easy to install even in hard-to-reach places. The device works with various control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16), which enables integration with existing alarm and control systems. It should be remembered that this detector is intended for use in normal conditions and should not be used in potentially explosive atmospheres.

Features and benefits

• Two-stage alarm: The detector has two alarm thresholds – 20 ppm and 100 ppm – which allows for a quick response to changes in CO concentration and appropriate notification of potential hazards.
• Replaceable sensor: The use of a replaceable semiconductor sensor (p-p) ensures easy maintenance and the ability to adapt the device to specific user needs.
• Optical signaling: A built-in multi-color LED indicates the device status and exceeding alarm thresholds.
• Event history: Built-in memory stores event history, making it easier to analyze the causes of alarms and optimize system performance.
• Thermal compensation: The thermal compensation circuit minimizes the impact of ambient temperature changes on measurement accuracy.
• Calibration: All detectors are factory calibrated in a laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees their high precision and reliability of measurements.
• Easy installation: Removable terminals facilitate the connection of single- and multi-strand wires without the need for crimp sleeves.

The DG-22/NL/W detector is a reliable solution for ensuring safety in places exposed to carbon monoxide – both for professional installers and end-users looking for effective protection against this silent killer.
