What are the differences between the three unlock conditions for inputs: latch, follow, and access?

Latch: Unlocks and stays unlocked if the input goes into alarm mode.

Follow: Follows the condition of the input. When the input goes into alarm mode, it unlocks the door or the group. When the input is restored, the door or group is locked.

Access: When the input goes into alarm mode, it unlocks the door or group for the defined unlock time for each door.
