Flammable gas detector - Measuring equipment - Model SAFE 808L

Intelligent detector of flammable and explosive gases with voice warning and digital display. The device was designed for detection and early warning of the presence of flammable and explosive gases (natural gas, methane, propane, butane) using the latest catalytic combustion sensor technology, which does not require further calibration.
The SAFE - 808L digital detector is ideally suited for detecting gas leaks from all domestic gas appliances and gas boilers. Detects all flammable gases commonly found in households.
The device is powered from a 230V / AC network with a 9V NiMH backup battery in case of a power failure in the mains (battery not included).
In addition to the usual functions, this device excels with completely new functions, which make it the absolute market leader in its category.

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

Digital display:
Displays flammable gas values ​​in ppm (or millionths). The digital display allows the recognition and comparison of low and high values ​​of potential danger.

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

Where to install the detector:

We install flammable and explosive gas detectors in rooms with a potential gas leak (gas boiler rooms, kitchens, rooms with wavkami, karma, direct heaters, heaters, etc.). The basic criterion for the correct placement of the detector is the identification of the gas, ie 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 detected gas either under 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 device to minimize false alarms, which they can occur during a short gas leak, for example when igniting a gas boiler or stove and at a distance of about 60 cm from the corners, ie the place where two walls converge.

Properties of gases and their weight in relation to air:

Propane butane (LPG): Heavier than air, sinks to the floor.
Natural gas (LNG, CNG): Lighter than air, it rises up to the ceiling.
Petroleum substances: Heavier than air, sinking to the floor.
Ethylene: Lighter than air, it rises up to the ceiling.

What is natural gas?
Natural gas is supplied to your house by pipeline. If you do not live in the countryside, you are probably using natural gas. It is the predominant energy for heating homes. Natural gas is a fossil fuel containing almost exclusively methane. Methane is much lighter than air and rises upwards 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 a gas leak is detected as quickly as possible.
What is propane Propane is most often supplied to the household in liquid form and is stored near the house in propane tanks. Propane is used in houses in the countryside where natural gas is not introduced. As propane is the most commonly used LPG (liquefied petroleum gas), they are often used with the same meaning for pan and LPG. Unlike natural gas, propane is much heavier than air and stays low to the ground. We therefore recommend installing this detection device low to the floor to ensure that a gas leak is detected as quickly as possible.

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