The entrance door into the faculty building is equipped with an electronic lock. This door tends to be locked whilst the guards are not present at their station when on night-time and weekend inspection patrols. You can open this lock by placing a valid Charles University student ID card on the card reader device. This card reader is located on the pillar to the left of the door (a small white box with a blue diode). To leave the building, place your student ID card on the card reader located on the wall to the right of the guardhouse. If everything is in order, a green diode will flash shortly after you place your student ID card on the card reader, the reader will emit a short beep and the door will then open.
If the reader flashes red and emits a long whistle sound, your card is not registered in the electronic system controlling the lock. Should this occur, contact an officer of the Computer Centre. If the reader does not respond to your card – i.e. the blue diode remains on, the chip inside your card is probably damaged and you need to contact the Card Issuing Centre (for information go to http://www.cuni.cz/UK-2763.html to arrange for a card replacement.
Access: every day, including Saturdays and Sundays when the school is open.
