Sentry Dimmable Fluorescent and Energy
Management Controls
The Sentry digital
controller interfaces manual and automatic lighting controls with dimmable electronic
fluorescent and compact fluorescent ballasts. The system provides optimal lighting control
flexibility while reducing lighting energy consumption. Sentry uses the lowest control
input level received from the manual and automatic controllers to set the lighting levels.
The manual controls provide direct control of the lights while the automatic controls
reduce lighting costs through efficient use of the lighting. The automatic controls reduce
cost with motion sensors to turn off lights in empty rooms, photocells for daylight
harvesting in sunlit perimeter areas, and time clocks for time-of-day control.
