Where do I mount my smoke detector or carbon monoxide detector?
Mounting a smoke detector
Because smoke always rises, you need to mount a smoke detector on the ceiling. It's important that a smoke detector can be heard in the bedroom. That's why you should mount a smoke detector at a distance of up to 3 meters from the bedroom. Don't hang it in the bedroom, because you'll react too late if the smoke has already reached your bedroom. Mount at least 1 smoke detector on each floor. In the kitchen, a heat detector would be more suitable, because it doesn't give a false alarm from water vapor.
Mounting a carbon monoxide detector
Unlike smoke, carbon monoxide doesn't rise. This gas lingers at about 1.5 meters. That's why you shouldn't mount a carbon monoxide detector to the ceiling, but at 1.5 meters. It's important that the detector is located close to the fuel consuming device, like a central heating system, or a gas stove, for example. When placing the detector, make sure that it can be heard in other places in the house.
