Apollo Soteria Dimension IR Optical Detector FL5100-600APO

Apollo Soteria Dimension IR Optical Detector FL5100-600APOThe Soteria Dimension Optical Detector contains two daylight filtered photo-diodes and three IR emitters in different positions and angles. Different combinations of these are used to act as smoke sensors and proximity sensors to measure the smoke level at the detector and to detect any physical obstruction or interference of the detector.As this detector is chamberless an IR LED emits light outside the detector. The light is scattered by smoke back towards the detector and registered by a photo-diode.A pair of microprocessors control these sensors setting the sensor timings and using a digital phase-sensitive detection algorithm to reduce noise and the effect of background light. They then provide digital filtering for transient rejection compensation for drift and temperature and ultimately make an alarm decision.Key FeaturesLow profile designUtilises digital CoreProtocol communicationsCompatible with Discovery and XP95 systemsIntegrated switchable isolator as standard8-way DIL switch addressingDrift compensationFasTest for quicker testingTricoloured LED status indicatorPolycarbonate moulding for colour stability and strengthComprehensively tested to exceed EN 54-7 and EN 54-17 standardsLocking mechanism grub screw

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 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
