  • Patent number: 5598139
    Abstract: An alarm system for producing substantially synchronized visual output indicia of the alarm condition includes a common source of pulses which is activated in response to the presence of the alarm condition. The common source of pulses generates a trigger pulse train having a predetermined period. The trigger pulse train is fed, via power supply lines, to a plurality of visual output devices which can be triggered in response to the arrival of each of the pulses in the train thereby producing a synchronized plurality of visual indicia indicative of the alarm condition. The output devices will produce an essentially synchronized plurality of visual indicia in the presence of the alarm condition even in the absence of the trigger pulse train.
