1. A fire alarm comprising:
- an electronic evaluator;
an optical module electrically coupled to said electronic evaluator;
a temperature sensor operatively coupled to said electronic evaluator; and
at least one combustion gas sensor electrically coupled to said electronic evaluator, the electronic evaluator diagnosing one of a plurality of fire types selected from the group consisting of TF1, TF2, TF3, TF4, TF5, and TF6 and selecting an application-specific algorithm based upon said diagnosed fire type for processing of the signals of the optical module and the said sensors.

Abstract
A fire alarm having an electronic evaluator, an optical module, a temperature sensor, and at least one combustion gas sensor, where the electronic evaluator diagnoses one of a plurality of fire types and selects an application-specific algorithm based on the diagnosed fire type. The electronic evaluator uses the signals from the sensors to diagnose at least one of a plurality of types of fire. The fire alarm may have at least one polarization filter which may be an active polarizer with electrically adjustable polarization plane.
