The Fire Security Unit is the result of the last student design assignment in a group setting. Our assignment was to design and develop a fire security system which can be installed in so-called IFD (Industrial Flexible Demountable) walls. Throughout the 6 months project thorough company (client), market, and contextual analyses have been carried out. This had lead to a prototype which is easy and flexible to install and use, essential for all involved stakeholders and application areas.
