A smoke alarm serves as the first line of defense in fire safety. Utilizing either photoelectric or ionization sensing technology, it detects smoke in its early stages and immediately triggers a loud alarm, allowing occupants to evacuate promptly. It is one of the most effective means to monitor and respond to early fires.
Installing smoke alarms is a critical measure to enhance household safety. However, improper installation can lead to device failure, reducing its effectiveness and increasing the likelihood of false alarms. In worst-case scenarios, it may even fail to alert during an actual fire. Correct installation is essential to ensure optimal performance, minimize false alarms, and improve fire prevention.
Choosing a Certified Smoke Alarm
First and foremost, select a smoke alarm that is fully certified. Look for the CE mark, which indicates compliance with the EU Construction Products Regulation (CPR) and the harmonized standard EN 14604. This standard specifies requirements for performance, safety, environmental durability, and test methods, ensuring the device detects smoke promptly and provides sufficient time for evacuation.
Testing Before Installation
Before installing a smoke alarm, you should first power it on and test the alarm to confirm that the audible and visual alarm functions are functioning properly.
Optimal Installation Position
Due to the tendency of hot smoke to rise, it accumulates near the ceiling. Installing the alarm on the ceiling, preferably in the center of the room, is highly recommended. Avoid mounting it on a wall, as this may delay smoke detection. Ensure there are no obstructions within 0.5 meters of the alarm. For larger rooms, the distance between two alarms should not exceed 10 meters.

It is advisable to install alarms near bedrooms and living areas, as well as in locations prone to fire. Each alarm can effectively cover an area of up to 60 m². Beyond this, blind spots may occur where detection is weak or delayed. For optimal safety, every separate room should have at least one smoke alarm.
Locations to Avoid
To prevent false alarms and ensure reliable operation, do NOT install smoke alarms in the following areas:
-
Kitchens or smoking areas where smoke or fumes are frequently produced.
-
Near ventilation openings, such as doors, windows, corridors, or exhaust fans.
-
Damp or high-humidity areas like bathrooms.
-
Environments with strong magnetic interference.
-
Places with excessive dust, fibers, or airborne particles.
-
Corners of walls or apexes of vaulted ceilings where airflow is restricted.
-
Locations where temperatures may fall below -10°C or rise above 50°C.
-
Outdoor settings.
-
Areas exposed to corrosive gases.
-
Do not install during renovation or any dust-generating activities—complete installation only after construction and cleaning are finished.
Conclusion
Proper selection and placement of smoke alarms are fundamental to enhancing home safety. By following these guidelines, you can ensure early and accurate fire detection, reduce false alarms, and most importantly—protect what matters most.
