Abstract
An optical smoke detector includes a radiant energy source and a sensor. The source and the sensor are carried by an optical block that provides a fixed orientation therebetween and barriers therebetween. The barriers reduce noise and false alarming due to bugs, dust, water vapor, and other intrusive elements. The barriers can include V-shaped members at a selective angle relative to center lines of the source and the sensor.
