The NC120 Central Equipment (CE) Module is scalable so that up to 20 CE modules can be networked together. Each CE module provides connections and power for 64 room controllers and up to six master stations. (Limit of 4 master stations on a CE module when LI484P5 4-LED multicolor dome lights are connected.)

CE modules can be stacked on a shelf or rack mounted

The NC120 CE Module includes two field-replacable backup batteries that provide system power during the facility's switchover to emergency generator power. The NC120 also includes the LS450 Config Tool programming software.
