Smoke caused by fire is very dangerous. especially because of today’s widespread use of synthetic materials in modern homes that might generate poisonous vapours when burning .
The smoke alarm detects smoke caused by smouldering at an early stage and warns by means of a loud. vibrant sound.thereby waking inhabitants up at a point of time when a safe escape is still possible.
The smoke alarm operates according to the scattered light principle .A light source and a photocell are arranged so as to ensure that normally no light striked the photocell. The light source is activated in short intervals.
if the concentration of smoke particles in the enclosure reaches a certain level,the light is reflected and reaches the photocell this will set off a loud fire alarm.
