IMPORTANT: INSURE THAT ALL FLUORESCENT LIGHTING FIXTURES ARE PROPERLY GROUNDED.
1. Use a 2" x 3" switch box or a 4" square or octagon junction box. Mount a box for each smoke detector and run the system fire detection circuit plus the power circuit to all smoke detector locations. See Wiring Diagrams, FIGURES A and B, for Latching Models, and FIGURES C and D for Self Clearing Models.
