Safety in Your Home – Gas Detector DK-12.A

The DK-12.A gas sensor is a reliable device designed for continuous monitoring of natural gas (methane) presence in residential and commercial premises. Its task is to detect potentially dangerous leaks early, ensuring the safety of you and your family. The detector is particularly recommended for installation in places where there is a risk of gas emission, such as boiler rooms, kitchens with gas appliances, or rooms with gas installation.

Functionality and Application

The device uses a semiconductor sensor to precisely measure the concentration of methane in the air. When the alarm threshold is exceeded – 15% of the Lower Explosive Limit (LEL) – the detector activates both optical (LED) and acoustic (85 dB) signaling, informing of the hazard. Additionally, the DK-12.A model has a relay output, allowing connection of external alarm devices, such as sirens or gas shut-off systems. This expands the security capabilities and allows for the creation of a comprehensive security system.

• Wide range of applications: ideal for boiler rooms, kitchens, bathrooms, garages, and rooms with gas installation.
• Cooperation with external devices: possibility to connect an external siren or gas shut-off system thanks to the relay output.
• 12V DC power supply: provides installation flexibility and the ability to power from various sources.
• Complies with PN-EN 50194 standard: guarantees compliance with European safety standards.
• Long sensor life: semiconductor sensor ensures reliable operation for approximately 15 years in clean air.

Construction and Technical Parameters

The DK-12.A detector is characterized by a compact design (85 x 140 x 55 mm) and light weight (0.4 kg), which facilitates its installation in various places. The device is powered by 12V DC and has a built-in optical and acoustic signal. Additionally, the detector is covered by a 3-year manufacturer's warranty – GAZEX – which demonstrates its high quality and reliability. It is worth remembering the recommended air humidity in the range of 30-90% for optimal device operation.

The DK-12.A detector is an investment in the safety of your home and family, offering peace of mind and protection against potential hazards related to natural gas leaks.
