T568B wiring pinout. Individual CAT-5e cable lengths must not exceed 200 ft. in order to prevent
network communication issues.
Model DC overhead ceiling fans are ideal for providing year-round comfort in air circulation and destratification
applications. Designed for commercial spaces with low to medium height ceilings, model DC provides quiet,
comfortable air movement that maximizes building efficiency by reducing load on the HVAC system. The DC's
light-weight direct drive motor and compact design also result in effortless installation, making the DC a smart
choice for any space.
