Abstract: A particle separation system for separating particles in an airflow upstream of a detection chamber in an aspirating smoke detector is disclosed. The particle separation system includes an airflow path for directing the airflow from an inlet to an outlet. The airflow path includes a first airflow path section in a first direction and a second airflow path section in a second direction, the first and second directions being different relative to each other. The airflow path also includes at least one electrically charged surface such that the airflow undergoes electrostatic precipitation as it traverses the airflow path. A method of separating particles in an airflow upstream of a detection chamber in an aspirating smoke detector is also disclosed.

Abstract: A smoke detecting method which uses a beam of radiation such as a laser (16), to monitor a region, such as a room (12). A camera (14) is used to capture images of part of the room (12), including a path of the laser beam. Particles in the laser beam scatter light (30), and this is captured by the camera (14) for analysis. A processor (20) extracts data relating to the scattered light (30) to determine the density of particles in the beam, to determine the level of smoke in the region. The laser may have a modulated output (38) so that images captured without the laser tuned “on” can be used as a reference point and compared to images taken with the laser turned “on”, to assist in determining the level of scattered light (30) compared to ambient light. Filters (24, 26) may be used to decrease signals generated from background light.

Abstract: A system and method of reducing the incidence of false alarms attributable to dust in smoke detection apparatus. The method includes obtaining at least two sample air flows, subjecting a first airflow to particle reduction and measuring the level of particles in the first airflow and generating a first signal indicative of the intensity. The method also includes measuring the level of particles in the second airflow and generating a second signal indicative of the intensity. The first signal is compared to a predetermined alarm level and, if the alarm level is achieved, the first and second signals are subsequently compared and an output signal is generated based on the relative difference between the first and second signals.
