Notifier SMART4 Ivory Intelligent Multi-Criteria Detector

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.

Notifier NFX-SMT3-IV Photo Thermal amp Infrared Multi-Criteria Detector - Ivory

Notifier NFX-SMT3-IV Photo Thermal Infrared Multi-Criteria Detector - IvoryThe Opal multi-criteria multi-sensor photo thermal and infra-red SMART3 detector is the environmentally friendly alternative to the ionisation detector a technology that is now over sixty years old. The SMART3 offers comparable speed of response to the ionisation technology for a fast flaming fire and is less susceptible to false alarms. It can be deployed with confidence in locations where the main risk is from fast-developing flaming fires. SMART3 moves the goal posts in the fight against false alarms by delivering enhanced false alarm immunity.In addition to being an effective alternative to ionisation units SMART3 offers better performance over the alternative technologies of dual angle or dual wavelength optical detectors and photo-thermal detectors. The integration of continual monitoring for all three major elements of a fire enables the SMART3 to respond far more quickly to an actual fire and has the highest immunity to nuisances.

Notifier SMART4 White Intelligent Multi-Criteria Detector

Notifier SMART4 White Intelligent Multi-Criteria Detector

Notifier SMART4 White Intelligent Multi-Criteria DetectorFires take many forms from a slow smouldering fire that produces large amounts of smoke and Carbon Monoxide but little heat through to alcohol fires that produce high temperatures very quickly without any evidence of smoke.The SMART4 has a sophisticated brain capable of intelligently combining the data from the four sensing elements to provide a fast response to real fires while remaining extremely resilient to false alarm incidents. Using a combination of Carbon Monoxide Heat Optical smoke sensing and Infrared flame sensing elements enables SMART4 to detect the broadest range of fire conditions providing the earliest warning.How the SMART4 worksThe SMART4 is configured 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 dynamically adjusts 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 sensor thresholds sensor gain time delays combination sampling rates averaging rates are dynamically adjusted. And if any sensor fails the sensitivity of the remaining sensors are adjusted to compensate and a fault condition is indicated.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. 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.Key FeaturesUnique true four sensor Multi-criteria detectorFully integrated Infra-Red sensor to support the fire alarm decisionCO gas sensing for fastest response to slow developing and smouldering firesHighest possible immunity to unwanted alarmsAutomatic drift compensation of smoke sensor and CO cellTwin LED indicators providing 360 visibilityWide temperature rangeBuilt in test switchStable communication with high noise immunity
