Edge Triggering

Things that are programmed to change when a schedule changes are deemed to be edge triggered. This means that by default, they are only checked and changed when the schedule changes state.

For example, if a door is programmed to unlock by a schedule, then it will only unlock at the point that the schedule becomes valid.

If at 10:00am, you assigned this schedule to a door's unlock schedule, then that door will not unlock until 06:00am the following morning. This is because the trigger that unlocks the door is the edge trigger that only occurs when the schedule changes from invalid to valid.
