This zone is the most difficult of all 5 zone's. 4 of the classrooms are outside which makes it very difficult
to pull the cable to the rooms. We had three main options.
Option 1 was to drill holes in each of the classrooms wallsand run the cable from classroom to class room.
This would have been difficult for 2 main reasons. Running conduit through each classroom is not an easy task,
and to make things more difficult, each of the particular classrooms has
beams that run the width of the room on the ceiling, and it would have been very difficult to drill through the beams
or install conduit or raceway around the beams.
Option 2 was to run conduit on the backside of the wall on the outside
of the building, and dropping the cable into each class room.
Option 3 was to run conduit on the roof of the building
and drop the conduit in to each classroom. We choose option 3 because we were already running cable to the roof
to make the connection to the Elementary School and we didn't want to have drill any more holes than we absolutely needed
to.
