C0808
Electrical
Dedicated low voltage (24 VDC) circuit controls the Energos Control Systems. The
line voltage circuits control all the standard ballast functions including A/B switch-
ing, Dimming and Emergency Battery Pack operations.
ECS occupancy sensors are available in two variations:
• Mounted in the end cap.
• The middle of an 8" (243.84cm) module.
The ECS system control-center is the Power Pack. The Power Pack, contained in
each Master Module, interrupts the circuits when parameters dictate. The Power
Pack can control up to 600 watts 120 VAC, and 1300 watts 277 VAC. A maximum
of 10 sensors can be used on a single Power Pack. There is no limitation to the
number of Power Packs that can be "daisy-chained" to a single ECS circuit.
Emergency battery packs can be used in conjunction with ECS for emergency
egress lighting since all listed packs operate for a minimum of 90 minutes.
EM Packs can be used as momentary lighting for emergency circuit for power
transitions, and smaller packs are recommended for this purpose.
Dimming ballasts can be used in conjunction with ECS. However, the control
system will only perform ON or OFF operations and will not affect the level of dim-
ming set by the dimming ballasts.
Factory installed ballast disconnect allows the ballast to be disconnected from and
reconnected to incoming power under load without turning the entire circuit off.
Serial Row Linking (SRL) provides multiple continuous row communication.
For every run that SRL is required, order the appropriate SRL end set from page 2
of this Specification Sheet. Consult Energos Application Guide for more detailed
definitions and examples.
Mountings
Cable suspension distances are on 48" (121.92cm) and 96" (243.84cm) centers,
and consist of a 4 1/2" (11.43cm) diameter canopy finished white enamel. A 1/16"
(0.16cm) diameter stainless steel aircraft cable accomplishes suspension and is
adjustable from 12" (30.48cm) to 36" (91.44cm). Power feeds are 18 gauge silver
braided cord with clear jacket.
Feature Specifications
Occupancy Sensors:
• Time delay is factory pre-set to 30 minutes.
• Time delay can be field adjusted from 30 minutes to a minimum of 30 seconds.
• Daylight hold-off is factory pre-set to 120 ft-candles (1291.67m-candles).
• Daylight hold-off is field adjustable from 120 ft-candles (1291.67m-candles)
down to 10 ft-candles (107.64m-candles).
• Sensors are designed for a detection area (sensitivity diameter) of 16'
(487.68cm) when suspended 10' (304.80cm) AFF. Lowering the sensor produces
a smaller area of detection. See chart and diagram for additional information.
