Gas sensor, domestic gas detector DK-15.A propane-butane, alarm 15% LEL, output for external siren + relay output, p-p sensor, 12V power supply (for home use)

Home Safety – Propane-Butane Gas Detector DK-15.A

This propane-butane (LPG) gas detector from GAZEX, model DK-15.A, is a reliable device designed for continuous monitoring of gas presence in residential and commercial premises. It provides a quick response in the event of a dangerous gas concentration, protecting you and your family from potential hazards. The device is powered by 12V, making it ideal for home use.

Functionality and Application

The DK-15.A detector uses a semiconductor sensor to precisely detect propane-butane. When the permissible alarm threshold is exceeded (15% Lower Explosive Limit), it activates both optical and acoustic signaling – a loud alarm warns of the danger. Additionally, the detector has an output for connecting an external siren and a contact output, allowing integration with other security systems, e.g., a gas shut-off valve.

The device will be useful in the following places:

• Boiler rooms with gas furnaces
• Kitchens and bathrooms with gas appliances (cookers, water heaters)
• Rooms with gas installation (meters, cylinders, pipes)
• Garages
• Rooms heated with portable propane-butane heaters
• School chemistry laboratories

Key Features and Benefits

• High sensitivity: Semiconductor sensor ensures precise detection of even low gas concentrations.
• Two types of signaling: Optical and acoustic inform about the danger in a clear and understandable way.
• Alarm outputs: Allow connection of additional alarm devices or security systems. The contact output allows for automatic gas shut-off in case of failure.
• 12V power supply: Safe and energy-saving solution ideal for home use.
• Durable construction: The detector is made of high-quality materials, which guarantees its reliability and long service life (the sensor has an estimated lifespan of approx. 15 years).
• Calibration: All GAZEX detectors are calibrated in their own Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which confirms the accuracy and reliability of measurements.
• 3-year warranty: Provides peace of mind and confidence in your purchase.

Installation and Operation

The installation of the detector is simple and intuitive. It should be mounted on the wall, at a distance of no more than 4 meters from the potential source of gas emission, at a height not exceeding 30 cm above the floor. It is important to avoid places exposed to direct sunlight, moisture, and strong electromagnetic fields. Regular inspection of the device and sensor replacement (every approx. 15 years) will ensure its proper operation for a long time.

Remember: The detector reacts to a dangerous gas concentration – it will not activate with short-term use of a cooker! The device is intended for continuous monitoring of gas presence in the room and warning of potential explosion or poisoning hazard.
