Electrical outlets, controls, switches, and fire alarm devices are dimensioned at specific heights above the finished floor, including outlets at 15 inches minimum, light controls and wall phones at 42 inches center, fire pulls and thermostats at 48 inches maximum, horn strobes at 84 inches, and exit signs at 96 inches. Reach ranges follow accessibility codes with a 48 inch maximum reduced to 44 inches for forward approaches over obstructions. General notes establish standard mounting heights unless otherwise noted.
