Abstract
A visual alert system including at least two visual alert devices conductively connected to form an array. Each visual alert device includes a control circuit. The control circuits of the visual alert devices are connected by a flash mode interconnect line. The control circuits, thus interconnected are capable of sensing changes in voltage between the first and second control circuits across the flash mode interconnect line and therefore between the first and second visual alert devices. The visual alert devices, through their respective control circuits, may be programmed and selectively switched to operate in a variety of flash modes including an alternating mode or a synchronous mode.
