Abstract
Hazard detector for providing a pre-alarm of a developing hazardous condition includes a detection module that detects a hazard level of smoke or carbon monoxide, a storage module that stores a pre-alarm threshold and an emergency threshold, a light source that generates light in a first color, a second color, and a third color, 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 receives the detected hazard level and compares it with the pre-alarm threshold and the emergency threshold. The processing module determines that the hazard level is greater than the pre-alarm threshold and less than the emergency threshold and generates an audible pre-alarm speech via the speaker that warns of the developing hazardous condition. The processing module also activates the light source in the second color.
