Abstract
Outputs from a plurality of different ambient condition sensors are cross correlated so as to adjust a threshold value for a different, primary, sensor. Cross-correlation processing can be carried out locally in a detector or remotely. To minimize false alarming, the alarm determination can be skipped if the output from the primary sensor does not exhibit at least a predetermined variation from an average value thereof.
