Dobrý deň, ako mam interpretovať nasledujúci parameter ? Citlivosť 2500 ppm +- 1500 ppm Tých 1500 ppm je povolená odchýlka merania ? (To by bolo príliš veľa, keďže pre alarm stačí 50 ppm) Alebo to udáva rozsah merania ? A teda od 1000 ppm do 4000 ppm ? Ale v takomto prípade mi nedáva zmysel údaj, že alarm je spustený už pri 50 ppm. Vopred ďakujem
Combined Detector of CO, Flammable and Explosive Gases SAFE 808COM

Combined Detector of CO, Flammable and Explosive Gases SAFE 808COM
SAFE 808COM Combined Flammable, Explosive Gas and Carbon Monoxide (CO) Detector with LCD Display
The SAFE 808COM is a smart combined detector with a colour backlit LCD display, a voice warning system and the latest electrochemical and semiconductor multi-function sensor technology for the detection and early warning of not only carbon monoxide, but also almost all flammable and explosive gases commonly found in households. It excels in stability, high sensitivity and long sensor life. It is ideally suited for detecting gas leaks from all domestic gas appliances and gas boilers.

Two Sensors and Double the Protection
The SAFE 808COM is an intelligent, standalone detector for carbon monoxide, flammable and explosive gases that can accidentally leak from domestic gas appliances or gas boilers. It is designed to protect what is most precious – your home, health and the lives of your loved ones. Thanks to its two sensors, it is able to detect two types of deadly threats. If the detector detects the presence of gas (natural gas, methane, propane-butane), it will trigger an audible warning via an 85dB siren, including a voice alert in Czech, and a visual warning from the red LED indicator. The SAFE 808COM is there to always warn you in time and provide continuous protection 24 hours a day, 7 days a week.
Multifunctional LCD Display for Easy Monitoring
For a clearer overview and control of the situation in the event of an alarm, the SAFE 808COM detector has a backlit colour LCD display that shows not only the values of the detected carbon monoxide or flammable gas, but also other supplementary information such as the backup battery capacity via a bar graph, connection to the mains, etc. The display allows you to easily distinguish between low and high gas concentrations so you can react appropriately to the situation. Whether it's a minor leak or a serious danger, you'll always be in the know.


SAFE 808COM Provides Voice Warnings
The SAFE 808COM will not only alert you with an acoustic signal, but also with a voice warning (in Czech) about the current status of the device, such as: "Welcome to the flammable gas detector, please wait 3 minutes, the device is initialising." In the event of a danger, the detector's acoustic alarm signal is accompanied by a repeated message informing you of the detected danger: "Attention please, carbon monoxide leak!" or "Attention please, gas leak!". This feature allows you to immediately recognise the situation and act without hesitation.
Maximum Reliability and Accuracy
The device uses two independent sensors for accurate detection, an electrochemical (CO detection) and a multifunctional semiconductor (flammable gas detection), which do not require calibration or other settings and at the same time meet the highest European safety standards. The detector is certified according to EN 50291 and EN 50194. This means you can rely on its flawless functionality without the need for regular service calibrations. The detector continuously monitors the air and immediately alerts you to dangerous gas concentrations – both visually and audibly.


Gas Detector Ensures Safety Even in the Event of a Power Cut
Unlike conventional detectors, the SAFE 808COM is equipped with a backup power system. An integrated fast-charging converter allows the connection of a backup 9V NiMH battery (battery not included), which ensures operation even during a power cut. Your safety thus remains uninterrupted under any circumstances.
Protects Your Life, Health and Property
Most flammable gases are normally odourless, which makes them difficult to detect. However, the SAFE 808COM is designed to reliably detect even minimal concentrations of gases and trigger an alarm before a dangerous level is reached. It thus protects you from the risk of explosion, fire or poisoning.


Simple Operation and Test Function of the SAFE 808COM Detector
The SAFE 808COM is equipped with a TEST button that allows you to simulate the presence of gas and verify the functionality of the device. Thanks to this function, you can be sure that your detector is working correctly and is ready to protect you and your home.
Long Lifespan and Low Maintenance Costs
Thanks to advanced second-generation electrochemical and semiconductor sensor technologies, the SAFE 808COM has a long service life and does not require any regular servicing. This means that the investment in this device will pay off in the long run.
