Maintainance Fire Installation

The fire detection installation of janskerkhof13(a) is working, but in a very bad state. Hence, there is maintenance planned. The work is scheduled from November 18th, until November 29th. However, the work is not so loud and should not place a burden on the labs. Except for two days, then the laborers are in lab and might affect your study, these days are: the 19th and the 25th, for these days the labs are blocked in fris for that reason.
Your free to work in k06 and k04, but the people are replacing smoke alerts etc, so perhaps bring some masking music.
