tyco MX detectors incorporate years of experience in detection technology and manufacturing to provide the latest fire detection and false alarm rejection techniques in an attractive, compact and highly featured yet surprisingly cost effective package. So how is this achieved ? Very low false alarm ­ MX FASTLOGIC ,HPO and CO Fire detection are used to virtually eliminate the possibility of false alarms without compromising detection capability.

Very early fire detection ­ CO fire detection provides exceptionally early warning especially for sleeping risks. In addition, MX VIRTUAL multi-sensor detectors support the use of group detection algorithms, which allow several detectors in a zone to be used to make detection decisions. Reliable ­ carrying out virtual detection in the panel keeps the intelligent detectors simple, which not only reduces cost but significantly increases overall system reliability.

Virtual Multi-Sensor detectors ­ allow the best detection mode for the application to be selected from the panel without having to physically change the detector. This concept of virtual detectors reduces detector costs and commissioning time and also reduces stock levels and service spares. The use of virtual detectors allows the panel to change from one detection mode to another, automatically as the building occupancy varies. Virtual detectors can also operate in two detection modes simultaneously.

Long life ­ as detection algorithms are carried out in the panel, future changes in detector applications and advances in technology can be accommodated by panel upgrades. Detectors will not need to be changed to keep up with changes in building use or technological advances.

Self-Verification - built-in self-verification enables panels supporting this function to instruct the detectors to carry out an automatic walk-test routine through manual or automatic intervention.

Optical smoke detectors Compensated optical (HPO) detectors Carbon monoxide fire detectors Compensated CO (CCO) detectors Fixed temperature detectors Rate-of-rise detectors Ionisation smoke detectors

Environmentally friendly detectors ­ the use of HPO, MX FASTLOGIC and CO fire detection enable all applications to be accommodated without the need for radioactive ionisation detection elements. Unique construction of optical detector chambers reduces susceptibility to dirt and extends detector life. MX detectors are made from recyclable materials and can be returned to Tyco for recycling.

Temperature indication ­ the multi-sensor detectors allow the panel to read and display the ambient temperature at the detector enabling advanced life safety procedures to be implemented particularly in marine and other critical life safety applications.

Quick and easy to service ­ Self verification, detector dirty level indication, automatic detector readdressing and a comprehensive range of detector service tools enable quick and easy system servicing.

MX Detection Algorithms tyco MX TECHNOLOGY incorporates the latest detection algorithms to maximise response to real fires whilst minimising false alarms.

MX FASTLOGIC Expert Detection Algorithms

MX FASTLOGIC smoke detection algorithms have been developed with the joint expertise of Tyco and the University of Duisburg. MX FASTLOGIC algorithms use "fuzzy logic" applied to Expert System rules based on over 80 years of recorded data. Applying fuzzy logic to these rules enables MX detection panels to differentiate between the smoke and temperature patterns of real fires and typical false alarm sources as well as passing standard fire tests MX FASTLOGIC operates with both optical and HPO smoke detection modes. MX FASTLOGIC algorithms are carried out in MX detection panels rather than the detectors. This has several advantages: w

The extra processing power of the panel means that the algorithms require a minimum of commissioning. By adjusting a single setting to one of three positions the algorithms can take account of other variations automatically. By keeping the technology in the panel, future advances can be accommodated by simply upgrading panel software. Detectors can be changed easily at the panel from normal detectors to MX FASTLOGIC detectors and vice versa, quickly and easily.



HPO High Performance Optical Detection

HPO algorithms are based on the highly acclaimed Tyco HPO detectors which use temperature compensation processing to provide a universal detector with a flat response to different test fires. The HPO algorithm responds well to fires where ionisation detectors are traditionally used, at the same time it is less sensitive to tests where optical detectors can trigger too quickly. With over 1,000,000 HPO detectors installed during the 1990's it has proved to be a reliable, environmentally friendly detection method, which significantly reduces false alarms from smoke detectors. Detection performance and false alarm rejection can be further enhanced by the ability to apply MX FASTLOGIC to HPO detection.


MX CCO Carbon Monoxide Fir e Detection

Carbon monoxide (CO) fire detection is a relatively new concept, which has been pioneered by Tyco. After more than 10 years research and development the first CO fire detector was launched in 1997. The CO fire detector offers a good general-purpose fire detector, which is far less sensitive to where it is positioned than a smoke detector. However, what makes CO fire detection really stand out is its unprecedented early detection properties, which make it ideal for sleeping risks. The inherent false alarm rejection properties of the CO fire detector also offer many specialist applications.

To broaden the application of the CO fire detector, tyco MX TECHNOLOGY includes the new MX CCO algorithm. This uses both time and temperature to provide a more universal detection solution which responds to all EN54 fire tests. The 800CH carbon monoxide fire detector can operate as a CCO fire detector and heat detector simultaneously, thus allowing two detectors to be installed for the price of one.

Figure 1 illustrates how CO fire detectors perform when detecting fires started in confined areas. Here the CO detector picks up a fire in a wardrobe 25 minutes before the wardrobe bursts into flames, thus setting off the smoke detectors. By this time CO levels are off the graph at nearly 500ppm Ð a level that quickly causes drowsiness and lethargy.

Figure 2 shows the advantages of using CO fire detection for detecting slow smouldering fires. The CO detectors at floor and ceiling level have both gone into alarm before sufficient smoke has entered the smoke detectors for any significant measurement to take place.

World-W ide Pr oduct Range

tyco MX TECHNOLOGY has used the combined knowledge in the field of fire engineering from the worlds leading fire detection companies to produce a range of products, which are capable of world-wide approval and will carry UL, VdS, LPCB & Marine approval from the outset. As the range of detection panels and systems which use tyco MX TECHNOLOGY increase, all sizes of commercial and industrial buildings and risks around the world will be able to take advantage of the technology.


Backward Compatibility

There are in excess 100,000 MINERVA, ZETTLER, GRINNELL AUTOCALL and WORMALD addressable fire panels installed around the world which will continue to be supplied and supported for many years. As these installations are extended, updated to latest standards & specifications or replaced, it is possible to bring the benefits of tyco MX TECHNOLOGY to these installations with minimum cost and disruption. Backward compatibility is therefore a crucial element of the tyco MX TECHNOLOGY concept.

Backward Compatibility Features Include:

w New detection panels are designed to enable the support of existing detection technologies and loop protocols. tyco MX VIRTUAL detectors use existing Tyco M600 and 900 low profile detector bases and address flags. This allows upgrades to take place in many applications without changing wiring. w Compatibility with existing graphical alarm management systems including FireGraph, ThornGraph, Zettler AV-300 and Wormald XL is being implemented.


w w w Many of the new detection panels use existing panel enclosures for easy changeout. New detection panels can be added to existing panel networks including ThornNet, TFXnet, FILNET and CCUnet.

tyco MX DIGITAL loop uses existing detection cable including twisted, untwisted, screened, unscreened and MICC cables.

Bringing it all together, tyco MX TECHNOLOGY provides the latest technology and standards to new detection systems, whilst also allowing existing installations to migrate and upgrade to these technologies.
