摘要： In a preferred embodiment, a fire extinguishing system for suppressing fi on cook stoves, fryers or other heating or heated devices with fire suppressant dispensed through nozzles is powered by batteries which provide current for both a detection circuit including a pair of heat sensors and control circuitry and current for a gas or electric house current shut-off. Preferably, the shut-off is operated acoustically upon sounding of an audible alarm which emits a signal to which the shut off is acoustically tuned. Preferably, the heat sensors are diodes but, in alterative embodiments may be thermistors or active temperature sensors. While a wireless link, such as an acoustical link, is preferred between the control circuitry and shut-off, a wired link may also be used. In order to facilitate mounting of both the heat sensors and nozzles, magnetic housings are utilized which retain studs extending from tees, 90 degree elbows or both. A heat sensor housing is secured to the magnetic mount by magnetic force, which heat sensor housing is in turn held securely proximate the heat source at appropriate locations.

摘要翻译： 在优选实施例中，用于抑制烹饪灶，油炸锅或具有通过喷嘴分配的灭火剂的其它加热或加热装置的火焰的灭火系统由为包括一对热传感器和控制电路的检测电路两者提供电流的电池供电 以及用于燃气或电动车间电流关断的电流。 优选地，在发出声音调谐关闭的信号的声音警报器的探测时，该关闭被声学地操作。 优选地，热传感器是二极管，但是在替代实施例中可以是热敏电阻或有源温度传感器。 虽然诸如声学链路之类的无线链路在控制电路和关断之间是优选的，但也可以使用有线链路。 为了便于安装两个热传感器和喷嘴，使用磁性壳体，其保持从三通，90度弯头或两者延伸的螺柱。 热传感器壳体通过磁力固定到磁性座架上，该热传感器壳体又在适当的位置处紧靠热源紧固。
