This module was built for a production line at my previous workplace, its purpose was to serve as a single alarm system controller for an entire production line. It monitored up to eight machines, each with its own alarm timer. If an alarm was triggered; a one second signal was given with the horn. That input would then be muted, and not give any more alarm until the current alarm situation had been cleared for a minimum of seven seconds.
