    • A battery-powered supplemental alert generator is disclosed that is adapted to be mounted in close proximity to, such as within 3 or 4 feet of, a conventional smoke, heat and/or fire detector/alert device. The supplemental alert generator operates in a relatively low power mode while listening for the nearby detector/alert device to generate a standard audible alert signal. Upon detecting that a monitored sound level has reached a particular threshold, the supplemental alert generator enters into a higher power analysis mode in which it analyzes the detected signal to assess whether it is an audible alert signal. If an audible alert signal is detected, the supplemental alert generator generates one or more supplemental alert signals, such as a 520 Hz audible square wave signal. The supplemental alert generator may be used to retrofit a house, hotel, or other building to comply with new standards or to otherwise increase the effectiveness of the existing detection/alert system.
    • 公开了一种电池供电的附加警报发生器,其适于安装在诸如常规烟雾,热和/或火灾探测器/警报装置的3或4英尺内的近距离内。 辅助警报发生器以相对较低的功率模式工作,同时监听附近的检测器/警报装置以产生标准的可听警报信号。 在检测到监视的声级达到特定阈值时,补充警报发生器进入较高功率分析模式,在该功能分析模式中,分析检测到的信号以评估其是否是可听警报信号。 如果检测到可听见的警报信号,补充警报发生器产生一个或多个补充警报信号,例如520Hz的可听方波信号。 补充警报发生器可用于改造房屋,酒店或其他建筑物以符合新标准或以其他方式增加现有检测/警报系统的有效性。

    • Various inventive features are disclosed for efficiently generating regulation-compliant audible alerts, including but not limited to 520 Hz square wave alert/alarm signals, using an audio speaker. One such feature involves the use of a non-linear amplifier in combination with a voltage boost regulator to efficiently drive the audio speaker. Another feature involves speaker enclosure designs that effectively boost the output of the audio speaker, particularly at relatively low frequencies. These and other features may be used individually or combination in a given alarm-generation device or system to enable regulation-compliant audible alerts to be generated using conventional batteries, such as AA alkaline batteries. Various examples of efficiently generated regulation-compliant audible alerts and further enhancing such audible alerts by utilizing speaker enclosure designs are provided.
    • 公开了各种发明特征,用于使用音频扬声器有效地产生符合规定的声音警报,包括但不限于520Hz方波警报/报警信号。 一个这样的特征涉及使用非线性放大器与电压升压调节器组合以有效地驱动音频扬声器。 另一个特征涉及扬声器外壳设计,其有效地提高音频扬声器的输出,特别是在相对低的频率下。 这些和其它特征可以在给定的报警发生装置或系统中单独使用或组合使用,以使用诸如AA碱性电池的常规电池来产生符合规定的声音警报。 提供了通过利用扬声器外壳设计来有效地产生符合规定的声音警报和进一步增强这种听觉警报的各种示例。
