If you are renovating a space and they show (4) existing fire alarm devices( there are many more new devices being installed in the sapce) in the space to be demolished and are in same exact location as new but you need to keep the system up and running as the loop these existing devices are on feed adjacent spaces how would you handle keeping the system active at all time? Thanks
