Smoke Detection System features Sample Port-Annunciation(TM).

Press Release Summary:

MatrixScan(TM) addressable virtual detector matrix system features sampling pipes routed from multiple detectors to crossover points, each with specific detector address. Each crossover is treated as independent device, having multiple alarm thresholds, smoke and level bargraphs. Up to 127 virtual detectors can be assigned per loop. MatrixScan configuration is implemented through function-setting dialog box accessible through Stratos UL Listed and FM Approved Command Modules.

Original Press Release:

AirSense Technology Sets the New Standard for Aspirating Smoke Detection by Developing the World's First Addressable Sample Port-Annunciation(TM) System

A major "first" in the aspirating smoke detection arena, providing sample port addressability that other aspirating systems can only aspire to.

October 23, 2007 - Portland, Oregon, AirSense Technology Limited, leading manufacturer of award winning Stratos® aspirating smoke detection systems is proud to introduce MatrixScan(TM), the world's first addressable virtual detector matrix system featuring sample port-annunciation(TM).

In accordance with NFPA 72, each sampling "port" of an air sampling smoke detection system shall be treated as a spot type detector for the purpose of location and spacing. With the unveiling of MatrixScan, the entire range of Stratos series detectors can actually be used to create a Virtual Detector Matrix System with relatively few physical detection units, providing sample port-addressability and the enhanced strength of cross zoning, while meeting national codes and standards.

"Our developments in aspirating smoke detector signaling architecture have enabled us to perfect and patent a revolutionary cross-matrix system. This innovative technology empowers AirSense Technology channel and industry partners with the ability to provide their customers with the very early warning advantages associated with Stratos aspirating smoke detection, point annunciation, plus the added reliability of cross zoning " said Steven Joseph, Chief Executive Officer of AirSense Technology USA Limited.

The principle of operation is that sampling pipes are routed from multiple detectors to a multitude of 'crossover' points as illustrated below. Each crossover point has a unique detector address and is treated as if it were an independent device, having multiple alarm thresholds, smoke level bargraphs, address, etc. Up to 127 virtual detectors can be assigned per loop. A combination of 2 fd
'crossover' sampling ports (A & B) in alarm means that virtual detector 1 is activated. Since a virtual detector is comprised of 'crossover' sampling ports from independent real detectors, a true cross zoned configuration is achieved, providing a reliable method for initiating the release of a suppression system.

MatrixScan configuration is simple to implement through an intuitive functions-setting dialog box accessible through Stratos UL Listed and FM Approved Command Modules or via a PC running SenseNET® System Management software.

Once an address is assigned, the individual sample port has all the characteristics of a physical detector.

"We put MatrixScan through extensive testing with various installation configurations to assure it works as advertised with any of our Stratos series aspirating smoke detectors" said Mark Symonds, Director of software development for AirSense Technology Ltd. "The introduction of MatrixScan represents a revolutionary achievement for AirSense Technology. We are now the first manufacturer to offer an aspirating smoke detection system capable of ultra high sensitivity with freedom from nuisance alarms and sampling port-addressability

Applications for MartixScan are practically anywhere logical zoning and point annunciation in open or partitioned spaces is desirable and possible1. This includes, but is not limited to, in-cabinet detection - where notification by cabinet is desirable; prison cells; casinos; office spaces; data centers and communication facilities; control rooms; semi-conductor plants; generator turbine halls; switch gear rooms; distilleries; initiation of suppression system release through a cross zoned detection configuration, etc.

1 In spaces subject to high air velocities where smoke is transported laterally to detection points or where stratification is likely to displace smoke, addressability at the point of origin is typically unlikely for any type of detector. This is especially true for passive type devices. The added cost of addressability or expectations of pinpointing the origin of a fire should be considered accordingly. Very early warning detection by "active" incipient detection systems, such as Stratos, enhances response time. Ultra high sensitivity without the nuisance of false alarms is a core feature of Stratos through its patented ClassiFire® technology.
