  • Method for Controlling an Acoustic Warning Device and Acoustic Warning Device That Performs Said Control Method
    Publication number: 20190076879
    Abstract: The invention relates to a method which is a more robust, flexible and easy-to-implement alternative to current methods for controlling acoustic warning devices. The method is essentially characterized in that it comprises analyzing and measuring the variation in voltage (UL) of a coil (6) and/or at least one variable property of said voltage (UL), the analysis being performed by a control circuit (10) during the disconnection transient of the coil (6) caused by an electronic switching device (20). The method is further characterized in that it comprises adjusting the frequency and pulse rate of a pulse generator (30) by means of the control circuit (10), where the adjustment is made according to a working condition in which a greater inductance variation is produced in the coil (6), that is, by adjusting the warning device (1) to the resonant frequency thereof.
