Alarm that goes off when a condition is true for too long. In constant combinator, set T to threshold of time in ticks (60 per second), and set F to frequency of alarm sound in ticks. Set the condition in the combinator marked "=" and hook inputs to it with RED wire only. (Default condition of "Everything = 0" works well for hooking up to a belt in pulse mode.) Change speaker settings as needed. C is count of ticks that condition has been true. S is sound counter.
