I did email Notts Fire Service but they were unimpressed offering little help. The accommodation houses over 400 students and probably bring in a substantial income for the city council. A case of politics before professionalism!
An independent inspection noted..."Faulty fire detection system: there is sufficient evidence from the complainant to substantiate the complaint here. I do feel that, like most of the other complaints, it was caused because the building was not finished. There is evidence of disruption. I am prepared to accept that the system is now properly installed and working, but that for a period of time there was a breach of this requirement of the Code.
The complaint must, therefore, be upheld on this issue."
Thanks for you interest and constructive comments AnthonyB.
