### Lighting Control

> MASTER - TO CONTROL ENTRY AND ROOM ONLY. ELECTRICAL ENGINEER TO SPECIFY ENERGY CODE COMPLIANT “MASTER OFF” FOR THE REQUIRED GUESTROOM LOADS. GMLD RECOMMENDS LUTRONS "CODE-SMART" SYSTEM THAT POWERS THE LIGHTING SHOWN HERE AS WELL AS TAKES INPUT FROM THIRD-PARTYDOOR CONTACTS, THERMOSTATS AND OCCUPANCY SENSORS. THIS SYSTEM MEETS THE ENERGY CODE REQUIREMENT TO TURN OFF LOADS AFTER A SPECIFIC PERIOD OF TIME AND ALSO PREVENTS LOADS FROM TURNING ON OR OFF UNEXPECTEDLY IN THE MIDDLE OF THE NIGHT.
