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:
Known responders designed to detect and respond to a the sound of a smoke alarm consume more power than is consistent with long battery life. They also rely on a prior knowledge of the frequency characteristics of the smoke alarm. The problem is solved using a processor (8), connected to receive signals derived from a microphone (5) and programmed to detect (20) a degree of consistency in one or more characteristics of bursts of sound from the smoke alarm (SD) before responding. This is preferably done using means (18) for examining measured periods and/or on/off ratios of the sound bursts. In this way it becomes possible to eliminate problems associated with high false alarm rates, high processor power requirements and the dependency on a knowledge of the characteristics of the smoke alarm. Furthermore, because the processor (8) needs only to detect consistency in the pattern of on/off pulses in the received signal, the processing power is a magnitude less than would be necessary for more complex methods.
Abstract:
The invention relates to novel methods and to devices for a measuring and analysis apparatus that measures impurities and/or particles in a gas or air. In a particle separation step, target particles having predetermined particle properties are separated from remaining particles from a gas or gas mixture such as air or a liquid, in short a fluid, that contains a particle mixture, and the occurrence and/or frequency of said target particles is determined in a measuring chamber. The likewise novel cooling of the radiation sources required for measurement permits the use of such having high power, as is required for measuring few particles or the smallest impurities. A further novel expansion of the electrical measurement range allows small but also abundant particles and impurities to be measured. In addition, a novel interface simplifies the start-up of the apparatus.

A dual condition fire/smoke detector system includes a housing and a sensor comprising at least two of a photoelectric sensor, a heat sensor, an ionization sensor or a carbon monoxide sensor disposed within the housing. A wireless communication system associated with the sensor enables communication of the detector with a remote device via a wireless receiver and a wireless transmitter. A light source associated with the housing may be positioned to illuminate an exit in response to a hazard detected by any of the aforementioned sensors.
