Where and at what height should sensors be mounted?
✔ Carbon monoxide (CO) detectors are typically mounted at adult face height, approximately 1.5–1.8 m above the floor.
Why?
Carbon monoxide mixes evenly in the air, so it doesn't rise or fall significantly. A height at breathing level allows for the quickest detection of the threat.
✘ What to avoid?
Do not mount near windows, fans or air vents (drafts interfere with the measurement).
Do not mount in nooks, behind furniture, near suspended ceilings or in places where air doesn't circulate.
Do not mount directly next to a gas oven or stove (false alarms).
✔ Ideally, it should be placed on the ceiling. Centrally, at the highest point of the room. At least 50 cm from the wall or corners, where air circulation is poor. If the ceiling is sloped (e.g., in an attic), install it 30–60 cm below the highest point, not directly at the peak (smoke can remain there in a "pocket" and later be detected).
Why?
Smoke rises upwards.
✘ What to avoid?
In the kitchen above the stove (steam and grease = false alarms), in the bathroom (steam), in drafty areas (near windows, fans, vents), near air conditioning, or right next to radiators or heating appliances.
✔ Methane is lighter than air, so it rises. Therefore, the sensor should be mounted: on a wall: 15 - 30 cm below the ceiling, preferably above the gas source (stove, boiler or heater), within a radius of 1-3 m from the appliance. Propane-butane gas (LPG – heavier than air) LPG sinks downwards, so the sensor should be mounted: low to the floor: 10-30 cm above the floor, near an LPG-powered appliance, within a distance of 1-3 m from the gas source.
Why?
Each gas behaves differently in air.
✘ What to avoid?
Mounting (of any type of gas sensor) in direct airflow: near windows, fans, grilles behind furniture or in alcoves (poor air circulation), in very dusty or greasy areas (e.g., directly above the stove), in the bathroom near the bathtub/shower (steam, moisture).
