Abstract
A dual sensor detector incorporates a fire sensor, such as a smoke or heat sensor, and a gas sensor. Control circuitry is coupled to the sensors. In response to a sensed fire condition, such as due to heat or smoke, a constant sample rate sampling parameter, such as a sample time interval or a drive amplitude, is increased for the second sensor so as to increase its signal-to-noise ratio and resolution. The second sensor will be operated with the increased sample interval or drive amplitude so long as the first sensor continues to exhibit the detection of a condition. When the first sensor drops outs of the detection of a condition, the alterable parameter of the second sensor is reset to its quiescent state which draws a lower current value.
