摘要： Fire rescue crew, on entering a burning building (1), will search rooms (1A to 1H) in a strictly specified order to ensure that every room is searched. A problem is that this procedure does not ensure that top priority is given to rooms that are likely to contain vulnerable persons such as children. The problem is solved using a visual signalling unit (5) mounted on or adjacent the door of a room (1F) identified as containing a vulnerable person and visible to rescuers in the access area. The signalling unit comprises: a microphone (6); means (9) for processing an output of the microphone so as to identify a sound emanated from a smoke alarm; and means (12, 12A) for generating, in response to such detection, a visual signal, visible to rescuers in the access area. A smoke alarm needs to respond immediately so as to alert occupants of a building and rescuers. However, there is inevitably a delay between detection of a fire and arrival of the rescuers in response to such detection. Because the purpose of the invention is to be seen by the rescuers, it does not need to respond immediately, unlike the smoke alarm itself. At least part of the delay (at least 15 seconds and preferably more) between detection of the fire and arrival of the rescuers can therefore be used usefully for processing the received sound signals so as to eliminate false alarms. But for this feature there would be a problem in distinguishing between the sound of a smoke alarm and other ambient noises such as music or bird-song.

摘要： 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.
