Abstract: There is described a duct detector (1) and components (2, 3, 6) for duct detectors. In one form the duct detector (1) includes: a port unit (3) and detector unit (2). The port unit (3) is mountable to a duct in use so as to position one or more ports in the duct. The detector unit (2) includes a detection region. The port unit (3) and detector unit (2) are reconfigurable between a close coupled configuration and a separated configuration in which the units (2,3) are mountable with a variable separation between them and coupled by one or more elongate conduits (12A, 12B) to provide fluid communication between the units (2,3).

Abstract: A method of particle detection in an aspirated particle detection system having a sampling pipe network and a particle detector. The method includes drawing sample air to the particle detector through the air sampling network; analyzing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

Abstract: A particle detection system including a particle detector in fluid communication with at least two sample inlets for receiving a sample flow from a monitored region. The particle detector includes detection means for detecting the level of particles within the sample flow and outputting a first signal indicative of the level of particles within the sample flow. A flow sensor is located downstream of the sample inlets for measuring the flow rate of the sample flow and outputting a second signal indicative of the flow rate of the sample flow. At least a first sample inlet is normally open to the monitored region for receiving at least part of the sample flow. At least a second sample inlet is normally closed to the monitored region but is openable to the monitored region in response to a change in environmental conditions in the monitored region. The particle detection system further includes processing means adapted for receiving the first and second signals and comparing the first signal to a predetermined threshold level and comparing the second signal to a predetermined threshold flow rate, and generating an output signal based on the respective comparisons of the first and second signals. A method of particle detection is also described.
