Abstract (en)

An alarm generates repeated pairs of primary and secondary light flash events when triggered. One light source produces primary flash events of visible light with a wide bandwidth of e.g. 200 nm. Another light source produces secondary flash events of visible light with a narrow bandwidth e.g. less than a third of the primary flash event. The primary and secondary flash events overlap wholly or partially or are consecutive.
