International Classification:

G08B 1700

US Classification:

340628, 340629, 340630, 340514, 340632

Abstract:

A microcontroller-based hazardous condition detector having an intelligent hush feature is presented. The microcontroller controls the operational mode of the detector by monitoring a single user-actuated switch, the inputs from a smoke chamber and a carbon monoxide detector circuit, and the current operating mode of the detector. When in a normal or no-alarm mode, actuation of the switch will cause the microcontroller to place the detector in a test mode of operation. If the detector is in a carbon monoxide alarm mode, actuation of the switch will act to reset the accumulator function of the microprocessor for the carbon monoxide alarm sensing. If the detector is in a smoke alarm mode, actuation of the switch may place the detector in a hush mode if the level of smoke is sufficiently low, or will have no effect if the level of smoke is too high. Once in the hush mode, actuation of the switch will place the detector into the smoke alarm mode. The microcontroller will also place the detector in the smoke alarm mode if the level of smoke increases beyond a certain limit, and after the expiration of a hush mode time limit.

International Classification:

G08B 13/14

US Classification:

340571, 340687, 3405683, 340628

Abstract:

A detector assembly is adapted to be removably secured to a female electrical receptacle connected to a power supply where the female receptacle is mounted at a surface of a structure. The detector apparatus includes a housing and an electrically powered circuit mounted in the housing. The circuit includes components operable to detect an alarm condition (such as carbon monoxide or smoke) and to provide an alarm in response to the detection. A primary power source includes a male electrical connector secured to the housing and extending outwardly there from. A secondary power source includes a battery connector mounted within the housing and adapted to removably receive a battery contained within the housing. The circuit is adapted to draw power from the secondary source in the event of a detected loss of power from the primary source. The apparatus includes a sensor for sensing displacement of the housing from the female electrical receptacle.
