Since version 5.12.2 we have access to the Mercury API item that controls overrides. This is awesome for 2 reasons:

1. It runs on "controller time" vs "server time" (No more converting to eastern!)
2. Overlapping a day to day schedule is no longer a concern.

Configuring an Override

1. Determine which doors need the override - generally only exterior doors will ever need to be altered; use your best judgement
2. NEVER set an override on an alarm
   1. 
3. Navigate to Physical Access
   
4. Use the checkboxes on the left to select the desired doors.
   
5. Click the override button.
   

6. Once inside the override box give the override a name, select the desired door mode, partition (your school), and select starting/ending time.
   

   Please make sure to select a partition. If not selected all users in the access control manager (including ones from other schools) will be able to modify your override!

Editing an Existing Override

Once an override is created it can be edited. 

1. Select the overrides button in the upper right.
   
2. Once inside click the name of the override.
   
3. Make required changes and click save.
