Abstract
A smoke detector dynamic range adjustment system includes a light emitting element for emitting light at a plurality of light output levels, the plurality of light output levels automatically adjusted by a controller when a saturation limit is approached. The system also includes a light receiving element for receiving light emitted from the light emitting element.
Claims13
A smoke detector dynamic range adjustment system comprising:
- a light emitting element for emitting light at a plurality of light output levels, the plurality of light output levels automatically adjusted by a controller when a saturation limit is approached;
- and
- a light receiving element for receiving light emitted from the light emitting element.
A method of increasing a dynamic range of a smoke detector comprising:
- emitting light from a light emitting element of the smoke detector;
- receiving light emitted from the light emitting element with a light receiving element;
- and
- automatically reducing a light output level of the light emitting element as a saturation limit of the smoke detector is approached to increase the dynamic range.
