Abstract
A multi-sensor gas detector includes a solid state heatable gas sensor, and at least one, different, infrared gas sensor. Emitted radiant energy from a heated surface of the solid state gas sensor, incident on the infrared gas sensor generates an output signal indicative thereof. The output signal and a signal from the solid state gas sensor can be coupled to evaluation circuits. The evaluation circuits can be implemented with a programmable processor and associated, executable control software to establish the presence of a target gas. One or more gas detectors can be incorporated into a regional monitoring system that includes a control unit coupled to a plurality of fire, smoke or gas detectors.
