From Robin Walker:

The automatic glass doors at the bottom of each Cripps Court staircase (and the lobby to the Bar) are now in operation.

From outside, you press a button to open the doors. With the exception of FF, there are buttons on both sides of the entry.

From inside, the doors will open automatically as you approach.

In the event of a fire alarm or electricity failure, all doors will open and stay open until the condition is reset.

For the time being, the University Card readers, although physically present, will not be in operation. There will be a further circular when these have been commissioned.
