  • Multi-Frequency Fire Alarm Sounder
    Publication number: 20080048841
    Abstract: An audible output device, of a type usable in a fire alarm system, incorporates a multi-frequency waveform generator. The generator produces a plurality of frequencies with predetermined duty factors during various time intervals on a repetitive basis. The multi-frequency drive signal is in turn coupled to an audible output device such as a piezoelectric horn or the like. The multi- frequency audio output provides an indicator to persons adjacent to the device of the presence of an alarm condition.

  • Multi-processor communications system incorporating prioritized messaging
    Publication number: 20060271667
    Abstract: A flexible multi-processor communications system supports variable message lengths and variable groups and application designations at respective processors. The receiving processors determine what action, if any, needs to be taken in response to the combination of group and application information in the messages. The receiving processors can include pluralities of pre-stored groups and applications along with associated priorities and the functions to perform.
