Abstract: A particle detection system 600 including; at least one light source (606) adapted to illuminate a volume being monitored (610) at at least two wavelengths; a receiver (604) having a field of view (620) and being adapted to receive light from at least one light source (606, 607) after said light has traversed the volume being monitored and being adapted to generate signals indicative of the intensity of light received at regions within the field of view of the receiver; a processor (624) associated with the receiver (604) adapted to process the signals generated by the receiver to correlate light received at at least two wavelengths in corresponding regions within the field of view of the receiver and generate an output indicative of the relative level of light received at the two wavelengths.

Abstract: A BEAM DETECTOR (10) INCLUDING A LIGHT SOURCE (32, 4500, 4740, 4958), A RECEIVER (34), AND A TARGET (36), ACTING IN CO-OPERATION TO DETECT PARTICLES IN A MONITORED AREA (38). THE TARGET (36), REFLECTS INCIDENT LIGHT (40), RESULTING IN REFLECTED LIGHT (42) BEING RETURNED TO RECEIVER (34). THE RECEIVER (34) IS A RECEIVER IS CAPABLE OF RECORDING AND REPORTING LIGHT INTENSITY AT A PLURALITY OF POINTS ACROSS ITS FIELD OF VIEW. IN THE PREFERRED FORM THE DETECTOR (10) EMITS A FIRST LIGHT BEAM (3614) IN A FIRST WAVELENGTH BAND; A SECOND LIGHT BEAM (3618) IN A SECOND WAVELENGTH BAND; AND A THIRD LIGHT BEAM (3616) IN A THIRD WAVELENGTH BAND, WHEREIN THE FIRST AND SECOND WAVELENGTH BANDS ARE SUBSTANTIALLY EQUAL AND ARE DIFFERENT TO THE THIRD WAVELENGTH BAND.

Abstract: In one form the present invention provides an apparatus (10) in an airflow path before a particle detector (38), wherein the apparatus (10) removes a substantially constant proportion of all sizes of airborne particles from the airflow over time. In a preferred form the apparatus includes a flow splitting arrangement (18) configured to divide a fluid flow into a plurality of sub-flows, the splitting arrangement 10 including means (22, 23) for defining a plurality of substantially identically dimensioned flow apertures configured to direct a portion of the fluid into a respective sub-flow.

Abstract: The invention relates to a particle detector, systems, and methods for detecting the presence of particles in a volume of air, most particularly it relates to detection systems and methods that use multiple modes of detection to detect the presence of particles. Preferably the particles being detected are particles that indicate an actual or incipient fire, or pyrolysis, such as smoke.

Abstract: A filter arrangement for removing impurities from a fluid is disclosed, the filter arrangement (10) includes a plurality of screen portions (18, 20) through which the fluid passes. The screen portions include a first screen portion (18) and a second screen portion (20) separated by a predetermined distance. The predetermined distance can be determined on the basis of a threshold particle length. In one form the filter arrangement (10) is mounted in a housing (16) which is configured to receive two filter elements (18, 20) arranged in a nested configuration. A particle detector using the filter is described.

Abstract: A beam detector (10) including a light source (32), a receiver (34), and a target (36), acting in cooperation to detect particles in a monitored area (38). The target (36), reflects incident light (40), resulting in reflected light (32) being returned to receiver (34). The receiver (34) is a receiver is capable of recording and reporting light intensity at a plurality of points across its field of view. In the preferred form the detector (10) emits a first light beam (3614) in a first wavelength band; a second light beam (3618) in a second wavelength band; and a third light beam (3616) in a third wavelength band, wherein the first and second wavelengths bands are substantially equal and are different to the third wavelength band.
