Gas sensor, domestic gas detector DK-22 A/E CO, alarm 50 ppm, output for external siren + contact output, electrochemical sensor, 12V power supply (for home use) DK-22.A/E

Home Safety – Carbon Monoxide Detector GAZEX DK-22.A/E

This carbon monoxide (CO) detector is designed for continuous air monitoring in residential and ancillary rooms where there is a risk of this colorless and odorless gas being produced. DK-22.A/E is a key element of the safety system, especially in places with fuel-burning appliances such as boilers, stoves, and fireplaces. When a dangerous CO concentration is detected, the detector activates both optical and acoustic signaling, and also activates alarm outputs allowing connection of external warning devices.

Application and Functionality

The DK-22.A/E detector finds application in a wide range of rooms:

• Boiler rooms (oil or gas)
• Kitchens and bathrooms with gas appliances
• Rooms with gas installations (valves, meters, cylinders)
• Rooms with fireplaces or solid fuel stoves
• Attached garages
• School workshops (physics, chemistry)

Thanks to the replaceable sensor module, the detector is easy and economical to operate. The sensor has an estimated lifespan of approximately 15 years in clean air. The device is powered by 12V DC, which ensures reliable operation.

Key Features and Benefits

• High efficiency: Uses a semiconductor sensor for precise detection of carbon monoxide.
• Alarm signaling: Built-in optical and acoustic signaling informs of danger.
• Alarm outputs: Allows connection of an external siren or other alarm devices (output to external siren and contact output).
• Replaceable sensor: Ensures easy and inexpensive operation of the device.
• Microprocessor control: Guarantees stable and precise operation of the detector.
• Versatility: Can work with many devices in the security system.
• Calibration: All GAZEX detectors are calibrated in their own laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).

Technical Parameters – What is Important to Know?

The DK-22.A/E detector has been designed with ease of installation and use in mind. Remember to install it correctly – the sensor should be placed on the wall, at the height of an adult's head or above 30 cm from the ceiling, near a potential source of CO emission. The device reacts to a carbon monoxide concentration of as little as 50 ppm (parts per million), in accordance with PN-EN 50291-1. The contact output allows integration with home automation systems or external alarm sirens.

Safety Confirmed

GAZEX detectors are a guarantee of high quality and reliability confirmed by a 3-year manufacturer's warranty. By choosing DK-22.A/E, you are investing in the safety of yourself and your loved ones, protecting them from the threat of the silent killer – carbon monoxide.
