As far as possible, place the detectors at regular intervals, prioritising areas

Installation precautions
Some phenomena can prevent self-contained smoke detector/alarms from
working properly:
-> Condensation in laundry rooms.
-> Appliances which may produce smoke (cooker hob, oven, vehicle
exhaust fumes, etc).
-> Make sure the room containing such appliances is well ventilated.
-> Smoke dilution by ventilation sources (air conditioning, heating,
window, other).
-> Dust in attics, lofts, workshops, etc.
-> Abnormally low (<0°) or high (>55°C) ambient temperature.
-> Steam in bathrooms. Self-contained smoke detector/alarms must not be
installed in bathrooms because of the risk of false alarms.
-> Vehicle exhaust fumes (in garages): risk of false alarms.
