Dusk to Time Operation
The exterior and site lighting is automatically turned on in the
evening by the schedule. An astronomic feature in the logic allows
the system to calculate sunrise and sunset times for the local area.
All exterior lighting is utilized during early evening hours. Later,
most of the exterior lighting is turned off by the schedule to
conserve energy and reduce sky glow. |

Adjusts to
Environmental Conditions
Stormy or overcast conditions may call for exterior lighting and
signage to turn on earlier than scheduled. A building-mounted
photocell monitors these conditions and passes light-level
information to the Synergy control system. On weekends and holidays,
photocell overrides are ignored.
Because the site lighting is spread out over a large area,
multi-pole lighting circuits are required to efficiently distribute
power to the lighting poles. The Synergy relay panel provides
integral control of multi-pole circuits without external contactors. |
