Résumé

Les alarmes-incendie peuvent sauver des vies dans une situation critique à condition que les gens les entendent. Pour que les dispositifs d’alarme d’un bâtiment soient vraiment utiles, il faut veiller à les placer aux bons endroits. On a défini une expression simple permettant de calculer l’atténuation du signal d’alarme provenant d’un détecteur de fumée au cours de sa propagation dans un bâtiment d’habitation, le trajet suivi étant considéré comme une série de pièces communicantes. L’atténuation dépend de la surface de plancher et du type de meubles et accessoires que contient chaque pièce. On effectue des corrections si la maison n’est pas dotée de chauffage à air puisé ou si un certain nombre de portes sont fermées. L’expression en question peut servir à déterminer le meilleur emplacement des alarmes.
