Abstract
A dual sensor fire detector includes a smoke sensor and a gas sensor. A source of radiant energy emits a primary beam that is formed into first and second beams. One beam is directed into a smoke sensing chamber. The other is directed to the gas sensor. Outputs from the smoke sensor and the gas sensor are combined to make a fire determination.
