  • Patent number: 5300923
    Abstract: An apparatus and method for use with a smoke detector that is located in proximity with a stove or similar smoke-emanating article. The smoke detector is enabled by placing the detector near the stove (or similar article) and/or applying a source of power to the smoke detector. The smoke detector is coupled to a device that operates to alleviate the accumulation of smoke that might emanate from the stove. Such a device might take the form of a stove hood or, specifically, a fan incorporated or associated with the stove hood. The smoke detector is mechanically and/or electrically coupled to the hood so that when the hood or fan is operating, the smoke detector is disabled and no alarm is communicated. The alarm may be automatically interrupted when the hood and/or fan are mutually deployed in an active (ON) mode.
