The digital inputs are normally used with security sensors, e.g. passive infrared sensors
(PIR), smoke detectors, etc. They work by detecting a change in the state of open and
closed circuit. The output ports are normally used to trigger external audio or visual in-
dicators, e.g. sirens or strobe lights, etc.
