So we have this new fire alarm system installed. There are several apartments in an old building. We have been told we need to do this weekly testing. One flat each week. I don't see why we can't just test all the flats at once every month, would be less hassle. If each flat was tested separately and there are over 4 flats, that is more than a month between tests for each one anyway. So how does testing each one weekly add anything (and just adds more faff / stress and need to create a plan for dates for each flat etc)
