Beschreibung
Zusammenfassung:	Hazard detector for providing a pre-alarm of a developing hazardous condition can include a detection module that detects a hazard level of smoke or carbon monoxide, a light source that generates light, a speaker that generates an audible sound, a horn that generates an audible alarm that a higher volume than the speaker, and a processing module. The processing module can receive the detected hazard level and compare it with the pre-alarm threshold and the emergency threshold. The processing module can determine that the hazard level is greater than the pre-alarm threshold and less than the emergency threshold and cause an audible pre-alarm speech to be generated via the speaker that warns of the developing hazardous condition.
