    • A microprocessor controlled hazardous condition detection system containing a sensor package, the sensor package containing sensors exposed to the ambient environment. The system also includes an alarm means coupled to the sensor package through a microprocessor having volatile and non-volatile memory. The microprocessor includes a memory storage device containing a plurality of alarm thresholds stored therein. Each of the plurality of alarm thresholds is associated with a predetermined set of ionization levels in the ambient environment. The microprocessor receives periodic ionization readings from the sensor package, and conditions the received readings by removing a selected amount of noise and attenuation therefrom. The microprocessor accumulates the conditioned ionization readings, selects and employs an optimized alarm threshold from the plurality of stored alarm thresholds, based on a set of the accumulated ionization readings. Upon detecting ionization levels in the ambient environment greater than the ionization levels linked to the selected alarm threshold the microprocessor causes the alarm means to generate an alarm condition.

    • A microprocessor controlled hazardous condition detection system and method containing a sensor package, the sensor package containing sensors exposed to the ambient environment. The system also includes an alarm means coupled to the sensor package through a microprocessor having volatile and non-volatile memory. In a preferred embodiment the hazardous condition detector is ionization-technology-based and optimized to readily detect smoldering as well as traditional flash fires. The microprocessor stores the periodic readings in the volatile memory, and calculates an average of a plurality of the periodic readings. The microprocessor analyzes the character/type of smoke by tracking the rate of rise of the sensor signal over a predetermined time period. Based on the progression of the rate of rise calculated from periodic sampling of the ambient environment the microprocessor evaluates the rate of ionized particle change and adjusts the alarm thresholding to readily detect both smoldering and flash fires.

    • A hazardous condition detector including a housing containing at least one sensor unit for sensing at least one ambient condition and a microprocessor contained within the housing operatively coupled to the sensor unit though a hardware interface. The hazardous condition detector also includes a memory means associated with the microprocessor, the memory means contains at least one alarm threshold value stored therein from which the microprocessor selects a single alarm threshold value, and user activated hardware control means operatively coupled to the microprocessor. The control means when activated by a user during an alarm condition reduces the sensitivity of the hazardous condition detector by changing the voltage across the sensor unit sensed by the microprocessor to a level that is within the range of a non alarm event defined by the single alarm threshold value selected by the microprocessor. During normal operation of the hazardous condition detector and during the hazardous condition detector's operation with reduced sensitivity, the hazardous condition detector employs the same alarm threshold value.
