Lockdown (sometimes referred to as Emergency Lockdown) will immediately 'lockdown' the door and prevent access from being granted with a valid card. Access will also not be possible using a request-to-exit button. Any doors put into lockdown, which are unlocked via an auto-unlock schedule, or have been unlocked from the Unlock Doors page, will also be locked.

To lockdown a door, for example, the front entrance door:

1. From the home screen, click the Unlock Doors tile.
   
   
   
   
2. The reader/door list will be on the left.
3. Locate and click on the door you wish to put into lockdown.
   
   
   
   
4. Click on the Lockdown icon.
   
   
   
   
5. The door will immediately go into the locked-down state.
