2.2 LIGHTING CONTROL System – Room controller (Stand alone)
| A. | System Description: |
| 1. | The lighting control system shall be a series of stand-alone room controllers for zone level switching. Low voltage switching and sensing devices connect to the room controller. The room controller interprets the various inputs and controls the room lighting based on the programmed sequence of operations. The system includes all interfaces and wiring, room controllers, occupancy sensors, couplers, power packs, relays, low voltage switches, and dimmers. The room controller shall be programmed as shown on the plans. |
