Notifier SMART4 Ivory Intelligent Multi-Criteria Detector

Notifier SMART4 Ivory Intelligent Multi-Criteria DetectorThe SMART4 combines 4 separate sensing elements to act as a single unit. CO sensing using EC technology for monitoring CO products from a smouldering fire IR sensing for measuring ambient light levels and flame signatures optical smoke detection and heat detection. The integration of continual monitoring for all four major elements of a fire has enabled us to create a detector that responds far more quickly to an actual fire and has the highest immunity to nuisances. The operating philosophy behind SMART4 was to configure it so that it normally operates at a high immunity level changing to become very sensitive to fires when fire characteristics are sensed. In this way transient nuisances are monitored and ignored reducing the false alarm rate.SMART4 is managed by on-board intelligence running some very advanced algorithms which dynamically adjust the detection profile of the device in response to the input from the sensors enabling it to be re-characterised on the fly as the ambient conditions change. Based upon the sensor signals the program is dynamically changing sensor thresholds changing sensor gain changing time delays changing combination changing sampling rates changing averaging rates and if any sensor fails changing sensitivity of the remaining sensors as well as indicating a fault condition.The IR light sensor helps the detector recognise specific situations such as welding and makes adjustments rapidly in order to further reduce the potential for false alarms caused by nuisances. The thermal detection function fuses thermistor technology with a software corrected linear temperature response. In areas where the normal daytime activities are likely to create unwanted alarms the detector can be programmed to operate on a Heat only mode automatically reverting to multi sensor operation during the unoccupied period. The SMART4 is thus able to offer exceptional false alarm immunity and excellent fire detection.
