1. You can only open the front doors at the front door itself.

2. At the front door you will find the ‘Open’ and ‘Close’ buttons. Hold these down to open and close the doors. First the left door opens, then automatically the right door.

3. Does the door not close? At the front door you will find a metal box. It is very important that nothing and/or nobody stands in front of it.

We strongly recommend that you keep the front door partially open during an activity for latecomers or early leavers. Therefore, do not close it completely unless the activity is over.
