Zusammenfassung:	A multi-sensor gas detector includes circuitry to evaluate if the detector is in compliance with predetermined safety requirements. Where the detector is in compliance, then a confidence indicator is intermittently activated at a predetermined frequency. Where the detector is out of compliance, the indicator is not activated providing indicia that the detector needs maintenance.
