Abstract
A fire sensor apparatus of the type having a discriminating fire sensor portion for detecting radiation in at least two different spectral bands associated with a fire and for providing an output signal in response to predetermined amounts of radiation in those spectral bands associated with a particular size and type of fire to be detected. A novel heat sensor channel is provided, which provides a further output signal in response to an amount of detected heat radiation greater than that associated with the fire of the type and size to be detected. A heat override function is thereby provided to permit the generation of an output signal even when contaminants block the action of the discriminating fire sensor portion.
