Hi Tom, This is extremely useful information. I work within schools, mainly contract management and recently visited a school that removed all the green brake glasses and replaced with key switches. This school has around 1100 students, 120 staff, visitors and members of the public using it in the evening for LETS. My concern is exactly what you have mentioned above, by removing the green brake glass, and the fire interface with the maglock failed, basically they have locked people in the building. Have you ever come across this situation and do you think its acceptable to put key switches on external/internal fire doors? Would this type of change need to be signed off by building control?
