Carbon monoxide and smoke detectors are vitally important devices that help protect your home and loved ones from the spread of dangerous gases and fires. The smoke detector detects smoke in the air and gives an early warning if a fire is starting. The gas detector is designed to detect the presence of gas, which is particularly dangerous because it is odourless and invisible. Smoke detectors should be installed either on the ceiling or on the wall, while gas detectors should be installed at a lower level because gas is heavier than air. If the smoke detector is beeping, it may indicate that the batteries need to be replaced or that the unit needs servicing. The best smoke detector is the one that is in working order - if your smoke detector is beeping, it's time to replace the battery or order a new one from Hansapost!
