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.

Claims

11 AMENDED CLAIMS received by the International Bureau on 13 December 2010 (13.12.10)
1. A responder designed to detect and respond to an alarm signal consisting of bursts of energy comprising: an energy sensor; means for deriving values defining the lengths, spacing or frequency characteristics of each of the said bursts; a store containing data defining a range of said values; and a processor programmed to determine (a) whether a derived value falls within the defined range and (b) whether the derived value remains consistent with itself over time within a specified tolerance; and means to activate an indicator in response to the processor determining that conditions (a) or (b) above are met
2. A responder according to Claim 1 characterised in that the said values are measures of the periods, or on/off ratios of the bursts
3. A responder according to Claim 1 or 2 characterised by a wake-up circuit connected to receive an output of the sensor and effective to produce a wake- up signal identifying the continuing presence of the said bursts over a period of time; the processor being arranged to be woken from a dormant state by the output of the wake-up circuit.
4. A responder according to Claim 3 characterised in that the processor is programmed to switch off its power if it determines that the derived value does not fall within the defined range.
5. A responder according to Claim 3 or 4 characterised in that the wake-up circuit comprises a rectifier followed by a low pass filter
6. A responder according to any preceding Claim characterised in that the processor is programmed to examine the said signals for consistency or changes for a period of seconds or minutes..
7. A responder according to Claim 6 characterised in that the said period is at least 15 seconds.
8. A responder according to any preceding Claim characterised by means for deriving timing information concerning the lengths, spacing or frequency of the said hursts and further characterised in that the processor is programmed to provide an indication of consistency of such timing.
9. A responder according to Claim 8 characterised in that the means for deriving the timing information is designed to identify the times of leading and trailing edges of the bursts.
10. A responder according to any preceding Claim characterised in that the processor is programmed to provide an indication of consistency of the frequency of the signal within bursts.
11. A responder according to any preceding Claim characterised in that the energy sensor is a microphone.
12. A responder according to any preceding Claim designed to respond to the sound from a smoke or fire alarm.
13. A responder according to any preceding Claim characterised in that the indicator is a strobe light source.
