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: Abstract A particle detection system, such as an active video smoke detection system, includes at least one illumination means for directing a beam of radiation through at least part 5 of the air volume being monitored, an image sensor is positioned to capture images of at least part of a beam from illumination means; and means to analyse the captured images to detect the presence of particles within the volume. At least 29 different aspects are described for improving the sensitivity, usability, and robustness of particle detection. These include, for example, configuring illumination means to create a 10 curtain of light or a rapidly-scanned beam across the air volume, and configuring a reflector to steer or change direction of a beam reflected from illumination means.

Abstract: A method of determining at least one point of entry of smoke into a smoke detection system, the system having a sampling pipe network including at least one sampling pipe and a plurality of sampling inlets through which an air sample can enter the at least one sampling pipe of the 5 smoke detection system for analysis by a particle detector, said method including: determining a volume of sample air that has passed through at least part of the smoke detection system since a predetermined event or a value corresponding to said volume; and determining through which sampling inlet of the plurality of sampling inlets the smoke entered the smoke detection system based, at least in part, on the determined volume or value. Systems for implementing such a 0 method and related methods are also described. Doc. 2005127028 16 i 22 +- 21

Abstract: There is describes a filter arrangement (10) for a particle detector (12) for detecting particles in an environment. The particle detector (12) can include one or more sensors (30) for analysing fluid in a detection region to produce sensor output. The filter arrangement (30) includes structure defining flow paths, for conveying fluid from the environment towards the detection region, including a first flow path (22), which includes a filter(26), and a second flow path (24) bypassing the filter(10). There is also provided a mechanism (120B) for controlling relative flow rates of fluid through the first flow path (22) and the second flow path (24) and a controller (32) configured to receive the sensor output corresponding to at least two relative flow rates and apply logic thereto to generate an output indicative of a condition of the filter.

Abstract: A beam detector (10) including a light source (32), 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 (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.
