  • Warning device status circuit including a status output device
    Patent number: 7023353
    Abstract: A warning device including a status and function indicator circuit for indicating the status and function of the warning device. In a visual warning device such as a strobe light, the status and function indicator circuit includes a status output device such as an LED. The LED and associated circuitry are configured to indicate both proper operation of the visual warning device and, in the event of a device failure, will indicate whether the fault lies with circuitry for the visual warning device or simply with a warning output device.
    Type: Grant
    Filed: April 7, 2004
    Date of Patent: April 4, 2006
    Assignee: Electronic Controls Company
    Inventors: Tony J. Tewell, Hans J. Kuhr
