Abstract (en)
[origin: EP1780685A2] An energy efficient, easily manufacturable, multi-sensor detector incorporates a smoke sensor and a thermal sensor. A single die programmed processor with integrally formed storage circuits for programs and parameters senses sensor signals, from different types of sensors, during a common activation cycle and processes those signals during the same cycle. The processor can also monitor the condition of an energy supplying battery and provide modulation signals to an audible output device. Other detector functions can be interleaved between output device modulation signals to minimize the cost of the programmed processor and thereby provide the required functionality very cost effectively.
