Local On/Off Controls (B)
Interactive Controllers: Fulfilling the need for user convenience, saving energy and centralized control at the same time.
For use in hallways, elevator lobbies, restrooms, meeting rooms, small offices, classrooms, and similar small public spaces. These are all spaces that have people going in and out, but not staying for long, each requires some form of user control.
LT3384(built-in relay) or LT2544(external relay)
Multiple Access Demo
During peak period, centralized control presides; but during off-peak periods, control is done automatically using local sensors, or manually with wall switches.
Local Switch Demo
The lights can be controlled at any switch, and will turn off automatically after a certain delay if the user forgets.
Hallways, Stairwells, Basement Parking
Turn on the lights manually, if the user forgets they turn off automatically after a certain delay.
Meeting room, reading rooms, small offices, research rooms.
Peak Period: Central control forcibly turns the lights on or off, local sensors are ineffective.Off-Peak Period: Control reverts to local sensors. People come, lights on, people leave, lights off.
Basement parking, showrooms, hallways, restrooms
(4) Large Spaces
Manual control, delayed auto off with all on/off at the doorway.
Warehouses, open offices.
Space Energy Savings
By combining sensors and switches, the following energy savings can be gained. Refer to EPA Energy Efficiency Report
