What are the Novel types of Smoke Detectors ?
Projected Beam type Projected Beam Smoke detector comprises two elements : a light source that transmits a beam of light and a detector that incorporates one or multiple light sensors (photoelectric cells). The smoke obscures the beam of light directed at the detector. The location of this system should be carefully selected so as to allow a clear line of sight between the light source and the detector. Aspirating (VESDA) This type of system aspirates the smoke from various locations into a tube where the smoke is analyzed electro-optically by a line of sight transmitter-receiver set.
