So the extraction system is all joined up again post truck incident. With the new flow controller and condensation barrier added. The flow control is stuck in the SHUT position. So please do NOT use the extraction system.
Also the door appears to have stopped working.
When you say the door has stopped working, could you elaborate?
I’ve looked online and it says @jonathanjo opened it an hour ago, and that you’ve using the shutter about 10 minutes ago?
I don’t suppose you noticed if the LED was on on the RFID reader board? It occurs to me that a wire could easily have been dislodged if you were working on the ventilation beside it.
If thats the case we’re in trouble as I am not sure who has the key for the door.
So I closed the shutter. Though to put a sign on the extraction control box. Opened the shitter. Went to operate the door sensor. No luck. Closed shutter again.
Yes I may have dislodged something 
I can’t do anything from here unfortunately, but if it was disconnected we will have to find a key or break in.
I have a key.
Will get the keysafe sorted ASAP
