Les deux diodes LED contribuent \u00e0 r\u00e9duire les fausses alarmes provoqu\u00e9es par la vapeur et la poussi\u00e8re. Ces fausses alarmes constituent l\u2019un des principaux facteurs qui am\u00e8nent les consommateurs \u00e0 d\u00e9sactiver, voire d\u00e9sinstaller, les d\u00e9tecteurs de fum\u00e9e. Selon la National Fire Protection Association, pr\u00e8s d\u2019un d\u00e9c\u00e8s sur quatre (23 %) aux \u00c9tats-Unis a lieu lorsque les d\u00e9tecteurs de fum\u00e9e ne fonctionnaient pas ou \u00e9taient d\u00e9sactiv\u00e9s. <\/p>\n

Le circuit ADPD188BI est con\u00e7u pour r\u00e9pondre aux nouvelles exigences de la norme UL217<\/a>, ainsi qu\u2019aux sp\u00e9cifications EN 54\/14604. Sa conception int\u00e9gr\u00e9e utilise deux couleurs pour distinguer lataille des particules, augmentant ainsi la capacit\u00e9 \u00e0 d\u00e9tecter et classer les types de fum\u00e9e, ainsi qu\u2019\u00e0rejeter les sources de nuisance. La solution propos\u00e9e par ADI permet de concevoir une approche de la r\u00e9trodiffusion o\u00f9 les diodes LED sont plus proches de la photodiode, ce qui r\u00e9duit la taille de la carte \u00e9lectronique et permet d\u2019utiliser des d\u00e9tecteurs de fum\u00e9e plus compacts et dont l\u2019architecture est davantage adapt\u00e9e aux usages r\u00e9sidentiels et commerciaux. <\/p>\n
