WARRANTY
Subject to the terms of this paragraph, the supplier warrants its title to the products sold by it and
warrants to the Purchaser that its products are free of defects in workmanship or material and are in
conformity with applicable specifications and descriptions of the supplier. No claim shall be maintained
hereunder unless the facts giving rise to it are discovered within 16 months from the date of shipment
from the factory, or 12 months after initial energization of said equipment, with the one expiring first
given precedence, and written notice thereof given to the supplier within 30 days of discovery. The sole
and exclusive liability of the supplier, for Breach of Warranty shall be, at its option, to replace or repair
the product or part concerned F.O.B. its factory or such place as it may designate. The warranties stated
in this paragraph are exclusive of all other warranties, written or oral, statutory, expressed or implied,
none of which shall apply to the sale of the suppliers products hereunder.
0-10V Outputs and Non-isolated Fixture Drivers
Connection of the E-Flex relay panel 0-10V analog dimming outputs to non-isolated fixture drivers is not
recommended. The E-Flex is designed to provide sinking control of fixtures that have a secondary Class 2
dimming circuit that is isolated from the mains power. Connection of the E-Flex 0-10V analog outputs to
non-isolated drivers, or drivers with Class 1 rated dimming circuits, will cause damage to the relay panel.
This damage is considered non-warranty.

four or eight zones as well 0-10V dimming. Inputs for occupancy and daylight sensors provide for
standalone energy management.
The following E-Flex relay panel models are available:
EFRP-04, 4 relays and 0-10V dimming
EFRP-08, 8 relays and 0-10V dimming
Features and Specification
Surface mount enclosure
4 or 8 mechanically latching relays with the following ratings:
oResistive: 50A @ 277VAC, 20A 347VAC
oTungsten: 20A @ 240 VAC, 277VAC
oStandard Ballast: 20A @ 120VAC, 277VAC, 347VAC
Electronic Ballast: 16A @ 120VAC, 277VAC
4 or 8, 0-10V outputs with current sink of 80mA.
Integrated +24V DC power supply to provide power for sensors and E-FlexNet devices.
Dry contact closure inputs for UL924, timeclock, fire alarm, and demand response.
4 banks of inputs for occupancy, daylight, and contact closure.
19 presets plus OFF for up to eight zones.
DMX512 input with RDM (Remote Device Management) support as well as Impress link mode to

Glossary of Terms
Demand Response -
Energy codes and energy companies have growing requirements to reduce your power consumption
during high-energy usage. The Room Controller meets these energy requirements by accepting a contact
input from the power company to impose a maximum output per zone.
LightsOut -
LightsOut is the period of time when lights should be at the LightsOut preset (typically, Off) unless there
is user intervention. Before activation of the LightsOut preset, lights will flash three times to warn
occupants of the upcoming change. After a delay the LightsOut preset will be activated. During this
delay, any button press at any station will further delay the activation of the LightsOut preset. Once the
LightsOut preset is in effect, light levels may be changed by a user. After 15 minutes of no inactivity, the
LightsOut sequence will start again.
Occupancy Mode –
Automatically turn lights ON when the occupancy sensor input detects the presence of a person and will
automatically turn lights OFF when no presence is detected for a specified amount of time.
Vacancy Mode –
Lights must be turned on manually by someone entering a room or area. The system will then
automatically turn lights OFF when no presence is detected on the occupancy sensor input for a
specified amount of time.
