Schedules
Schedules are definitions of timeframes. They can be programmed to:
 Have multiple start and stop times
 Work on some days, but not others
 Span multiple days
 Operate differently on holidays
 Be qualified by an output state
Uses
Schedules are used to:
 Control when a user can gain access to things
 Unlock doors automatically
 Arm or disarm Areas at certain times or days
 Turn things on and off at particular times or days
 Change how things behave at certain times or days
States
Once a schedule is programmed and active, it will always be in one of two states: valid or invalid.
When a schedule becomes valid, items that are programmed to depend on that schedule will become active.
For instance:
 An Access Level will only grant access when its operating schedule is valid
 A door will unlock when its unlock schedule becomes valid
 An output will turn on when its activation schedule becomes valid
Validation
When a user tries to gain access to something, the schedule is checked at that time.
 If the schedule is valid, access will be granted
 If the schedule is invalid, access will be denied
