Detection is provided by a highly sensitive catalytic combustion sensor, which requires no further calibration.\u003cbr\/\u003e\u003cbr\/\u003eShould a gas leak be detected, visual and audible alarms are activated and the output relay is triggered, which initiates the next step in accordance with the connected peripheral device. The alarm is deactivated once the gas concentration falls below the threshold value that triggered the alarm. The device features an automatic diagnostic system that monitors the sensor and internal circuits. If the detector’s diagnostics detect any irregularities, an audible buzzer signal will sound and the yellow ‘ERROR’ LED indicator will flash.\u003cbr\/\u003e\u003cbr\/\u003eThe detector is powered by a safe 12V DC voltage via a 230V \/ 50Hz mains power supply, which is included in the pack.\u003cbr\/\u003e\u003cbr\/\u003eAreas of use: Residential premises with kitchens fitted with gas hobs, domestic boiler rooms with appliances burning natural gas or propane-butane, or rooms housing gas equipment such as: gas cylinders, tanks, gas pipework, garages for gas-powered cars, and school chemistry and physics workshops and laboratories.\n\nWhere should the detector be installed?\u003cbr\/\u003e\u003cbr\/\u003eWe install detectors for flammable and explosive gases in rooms where gas leaks may occur (gas boiler rooms, kitchens, rooms with water heaters, central heating boilers, direct-heating heaters, fan heaters, etc.). The key criterion for correct detector placement is the type of gas being detected – in other words, whether we are detecting a light gas (which rises towards the ceiling) or a heavy gas (which sinks towards the floor). We select the installation location based on this criterion. Gas detectors are always mounted on the wall; depending on the type of gas being detected, they should be positioned either near the ceiling (approx. 15–30 cm) or above the floor (approx. 15–30 cm), at a distance of at least 1.2 m from any fuel-burning appliance to minimise false alarms, which may occur during a brief gas leak – for example, when igniting a gas boiler or cooker – and at a distance of approx. 60 cm from corners, i.e. where two walls meet.\u003cbr\/\u003e\u003cbr\/\u003eProperties of gases and their density relative to air\n\nPropane-butane (LPG): Heavier than air; sinks towards the floor.\nNatural gas (LNG, CNG): Lighter than air; rises towards the ceiling.\u003cbr\/\u003ePetroleum products: Heavier than air; they sink towards the floor.\nEthylene: Lighter than air; it rises towards the ceiling.\n\nWhat is natural gas?\u003cbr\/\u003e\u003cbr\/\u003eNatural gas is supplied to your home via pipes. Unless you live in the countryside, you are likely to be using natural gas. It is the predominant energy source for heating homes. Natural gas is a fossil fuel consisting almost entirely of methane. Methane is much lighter than air and rises upwards when it leaks.\n\nIf you use natural gas, we recommend installing this detection device about 30 cm from the ceiling to ensure that any gas leak is detected as quickly as possible.\u003cbr\/\u003e\u003cbr\/\u003eWhat is propane?\n\nPropane is most commonly supplied to households in liquid form and is stored near the house in propane tanks. Propane is used in homes in rural areas where there is no natural gas supply. As propane is the most commonly used LPG (liquefied petroleum gas), the terms ‘propane’ and ‘LPG’ are often used interchangeably. Unlike natural gas, propane is much heavier than air and tends to pool near the ground. We therefore recommend installing this detection device close to the floor to ensure that any gas leak is detected as quickly as possible.\n\nIt is therefore important to protect your family and home with combustible gas detectors.\n\nAdvantages of the device:\u003cbr\/\u003e\u003cbr\/\u003eA cost-effective device for detecting flammable gases.\nHigh-sensitivity catalytic sensor.\nWide range of detected gases: natural gas (LNG), methane, propane, butane and propane-butane mixtures (LPG)\u003cbr\/\u003eRelay output for controlling connected peripherals\nAudible alarm – an 85 dB siren alerts you to a detected hazard.\u003cbr\/\u003eReliability and high sensor stability.\nAutomatic diagnostic system with automatic sensor failure indication.\nInformation and warning LED indicators.\nPower supply with a safe voltage of 12V DC.\u003cbr\/\u003eCertification confirming compliance with standards ČSN EN50194-1: 2009 and ČSN EN50194-2: 2006\nEasy installation and operation.\nLoud alarm signal.\u003cbr\/\u003eWall mounting.\nVery low running costs.\nVery compact dimensions and low weight.\u003cbr\/\u003eModern and aesthetically pleasing design.\n\nTechnical specifications:\n\n- Gases detected: natural gas (LNG), methane, propane, butane, propane-butane mixtures (LPG)\u003cbr\/\u003e- Sensor type: catalytic – hot-wire sensor\n- Alarm thresholds: 12% LEL (lower explosive limit)\nPropane 0.20%\nButane 0.17%\u003cbr\/\u003eMethane 0.53%\n- Alarm signalling:\nvisual – flashing red ‘ALARM’ LED indicator\naudible – 85 dB siren audible at a distance of up to 3 m\u003cbr\/\u003e- Relay output\nmax 1A \/ 120V AC; 2A \/ 4V DC\n- Normal operation:\nthe green ‘POWER’ LED is lit\u003cbr\/\u003e- Fault indication:\na yellow LED flashes and an audible buzzer sounds\n- Maximum power consumption:\n1W in standby mode; 1.5W in alarm mode\u003cbr\/\u003e- Power cable length: 2.2 m\n- Operating mode: continuous\n- Operating temperature: -10°C to +40°C\n- Storage temperature: -20°C to +60°C\u003cbr\/\u003e- Operating relative humidity: max. 95% RH\n- Power supply: DC 12V ± 5%\n- Mains power supply: AC 230V\/50Hz, 9W DC12V 300mA (included)\u003cbr\/\u003e- Protection rating: IP 20\n- Service life: min. 5 years\n- Warranty: 36 months\n- External dimensions \/ weight: 75 x 75 x 35 mm \/ 66 g\u003cbr\/\u003e- Housing material: ABS plastic\n- Certificates and approvals: ČSN-EN50194-1:2009, ČSN-EN50194-2:2006, CE","brand":"GARVAN","offers":[{"title":"Default Title","offer_id":55154326929746,"sku":"08831557","price":690.0,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/08831557.jpg?v=1792522304"}],"url":"https:\/\/tipa.eu\/en-hu\/collections\/brand-garvan.oembed","provider":"TIPA","version":"1.0","type":"link"}
