SAFE 808L flammable gas detector

Product detailed description

SAFE 808L flammable gas detector
Flammable Gas Detector - Measuring Equipment - Model SAFE 808L

Intelligent flammable and explosive gas detector with voice alert and digital display. The device has been designed for detection and early warning of flammable and explosive gases (natural gas, methane, propane, butane) using the latest catalytic combustion sensor technology that does not require additional calibrations.
The SAFE - 808L digital detector is ideally suited for the detection of gas leaks from all domestic gas appliances and gas boilers. It detects all combustible gases commonly found in households.
The device is powered from 230V/AC mains with a 9V NiMH battery backup in case of mains power failure (battery not included).
Beyond the usual functions, this device stands out with completely new features that make it the absolute market leader in its category.

Function test:
The device is equipped with a test function, which serves to artificially simulate the presence of gas and allows the operability of the internal circuits to be verified through an automatic efficiency monitoring system.

Digital display:
Displays the combustible gas values in ppm (millionths). The digital display allows the recognition and comparison of low and high values of the potential hazard.

Voice alert function:
The acoustic signal of the alarm siren is accompanied by a human voice (in Czech language) informing about the detected danger "PLEASE ATTENTION!, GAS LEAK!".

Where to install the detector:

Flammable and explosive gas detectors are installed in rooms with potential gas leakage (gas boiler rooms, kitchens, rooms with hot tubs, karma, straight pipes, thermometers, etc.). The basic criterion for the correct placement of the detector is the identification of the gas, i.e. whether we will detect light gas (rising up to the ceiling) or heavy gas (falling to the floor). According to this criterion we will choose the installation location. We always install the gas detector on the wall, depending on the type of gas detected, either below the ceiling (approx. 15-30 cm) or above the floor (approx. 15-30 cm), at a distance of at least 1.2 m from the fuel-burning appliance to minimize false alarms that may occur during a short gas leak, for example, when igniting a gas boiler or stove, and at a distance of approx. 60 cm from the corners, i.e. the point where the two walls converge.

Properties of gases and their mass relative to air:

Propane butane (LPG): heavier than air, sinks to the floor.
Natural gas (LNG, CNG): lighter than air, rising up to the ceiling.
Petroleum substances: heavier than air, sink to the floor.
Ethylene: Lighter than air, rises up to the ceiling.

What is natural gas?
Natural gas is piped into your house. If you don't live in the country, you probably use natural gas. It's the predominant energy for home heating. Natural gas is a fossil fuel containing almost exclusively methane. Methane is much lighter than air and rises upward when it escapes.
If you are a natural gas user, we recommend installing this detection device about 30 cm from the ceiling to ensure that gas leaks are detected as quickly as possible.
What is propane? Propane is most often delivered to the home in liquid form and is stored near the home in propane tanks. Propane is used in homes in rural areas where natural gas is not piped in. Since propane is the most commonly used LPG (liquefied petroleum gas), the terms for pan and LPG are often used with the same meaning. Unlike natural gas, propane is much heavier than air and stays low to the ground. It is therefore recommended that this detection device be installed low to the floor to ensure that a gas leak is caught as quickly as possible.

It is therefore important to protect your family and home with combustible gas detectors.
