    Abstract: A particle detection system (10) including a particle detector (16) in fluid communication with at least two sample inlets (14, 24) for receiving a sample flow from a monitored region. The particle detector (16) 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 (30) is located downstream of the sample inlets (14, 24) 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 (34) is normally open to the monitored region for receiving at least part of the sample flow. At least a second sample inlet (36) 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 (10) 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.

    Abstract: A method of particle detection in an aspirated particle detection system, the system having a sampling pipe network and a particle detector. The sampling pipe network includes at least one sampling pipe in fluid communication with the particle detector, a plurality of sampling inlets through which sample air can enter the at least one sampling pipe, and an opening in the at least one sampling pipe upstream of the plurality of sampling inlets, wherein the opening has lower flow impedance than any one of the sampling inlets. The method includes drawing sample air to the particle detector through the air sampling network; analysing 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: THE PRESENT INVENTION RELATES TO A SENSING SYSTEM AND METHOD FOR DETECTING PARTICLES IN AN AIR VOLUME, WITH AN INCREASE IN MOMENTUM AROUND A SAMPLE COLLECTION SITE. THE INVENTION INCLUDES A PARTICLE DETECTOR AND A MAIN AIRFLOW PATH (A, F) INCLUDING AN INLET FROM THE AIR VOLUME. ALSO INCLUDED IS A SAMPLE COLLECTION SITE (E) WITHIN THE MAIN AIRFLOW PATH. THE SAMPLE COLLECTION SITE IS FOR DRAWING AN AIR SAMPLE FROM THE MAIN AIRFLOW PATH TO THE PARTICLE DETECTOR. ADDITIONALLY THE SYSTEM INCLUDES A MEANS TO INDUCE A LOCALISED INCREASE IN PARTICLE SPEED AT THE COLLECTION SITE (E) BY AN AUXILIARY AIRFLOW PATH (K) FROM THE MAIN AIRFLOW PATH. THE AUXILIARY AIRFLOW PATH (K) HAS AN EXIT (I) UPSTREAM OF THE COLLECTION SITE. THE LOCALIZED INCREASE IN PARTICLE SPEED IS RELATIVE TO AIR SPEED UPSTREAM OF THE AUXILIARY AIRFLOW PATH EXIT. IN AN ALTERNATIVE FORM OF THE INVENTION, THE MEANS TO INDUCE THE LOCALISED INCREASE IN PARTICLE SPEED AT THE SAMPLE COLLECTION SITE COMPRISES A VENTURI IN THE MAIN AIRFLOW PATH WITH THE SAMPLE COLLECTION SITE BEING DISPOSED ALONG THE VENTURI.
