The completed transponder new or extension request can be sent by mail or handed in personally to the GSG (preferably room 0.015). The transponder is issued promptly after receipt of the application. For extensions, expansions and restrictions there is no issue of another transponder. If you have any questions, please do not hesitate to contact us in person or by e-mail (transponder@informatik.uni-bonn.de).

In case of loss of your transponder please contact the employees of the GSG immediately. You can reach us by mail to transponder@informatik.uni-bonn.de. Please send us your full name and (if available) the transponder number.

If a transponder with locking authorization for interior, intermediate and/or room doors is lost, a lump sum of €50 for the reprogramming of all doors concerned will be demanded from the responsible workgroup. If there is a locking authorization for external doors, this sum will be increased to €100.

In the event of failure or non-timely reporting of a loss, the resulting damage (theft, damage to property, etc.) can be fully expected of the transponder holder.

In the non-activated state, the outside knob of the cylinder turns freely. Opening or closing the door is not possible. Hold the transponder at a distance of approx. 10 to 20 cm from the digital locking cylinder and briefly press the transponder button once. If it is an authorized transponder, a double beep will sound and the cylinder will engage. Now turn the outside knob in the locking or opening direction. You have about five seconds to complete this process. Then a single beep will sound and the outside knob will turn freely again. If it is an authorized transponder outside the authorized time zone, a single beep will sound. However, the cylinder does not engage and the door can not be opened. When trying to open a door with a transponder without a lock authorization, no signal will sound and the cylinder will not engage.

If the main battery of the lock cylinder becomes empty, after pressing the transponder before the cylinder is engaged, eight short, rapidly successive beeps can be heard.

In case of emptying cylinder batteries, please contact the GSG immediately to initiate a battery replacement. If the charge of the batteries is too low, the door could be hard to open even for us, so it is in your interest to give us early notice about low batteries in lock cylinders!

If the battery voltage of the transponder gets low, the lock cylinder will sound eight short, successive beeps afte every transponder actuation.

The replacement of the battery must only be carried out by qualified personnel. Please do not make an attempt to change it yourself to prevent damage to the transponder. Come by the offices of the GSG and have the battery replaced.
