Third-Party Fixtures
CAUTION:
Setting the F-Drive W1 CC Driver to output more current than
the manufacturer recommends for the loads may reduce the lifetime or cause
damage to the load. See
Configure the W1 CC Driver on page 22
CAUTION:
Do not exceed any Class 2 limits stated by the manufacturer of
the third-party load.
The W1 CC Driver and W1 CV Driver support a wide variety of third-party loads. Determining
compatibility between these loads and the driver is an important step toward ensuring the
success of a project. Search the
LED Dimming Compatibility Database
at
to see if your load is compatible. If your load is not in the
compatibility database, follow the instructions at the link above to contact the ETC Applications
Engineering department to arrange for compatibility testing.
Visit the F-Drive System Design Tool (
etcconnect.com/Products/Power-Controls/LED-Drivers/F-
Drive/F-Drive-System-Design-Tool.aspx
) to design an F-Drive R12 rack unit or F-Drive W1 driver
with different luminaires, breakout boxes, cable lengths, and other system components.
Emergency System Overview
The W1 Emergency Driver is a UL924 listed variant of the W1 Driver. The W1 Emergency Driver
is available in constant current, constant voltage, and Fade to Warm models.
Install the W1 Emergency Driver in a location that is accessible by qualified personnel for testing
of the emergency operation.
Note:
Installation must follow all national and local codes for electrical equipment.
Note:
Normal and emergency wiring cannot be contained in the same conduit
according to NEC 700.10(B).
W1 Emergency Functionality
The W1 Emergency Driver requires two circuit connections. These inputs have the following
functions:
1. "Sense" input. The "Sense" input accepts 40-300 VAC or VDC. There are two options for
"sense" input:
•
A normal mains supply circuit to sense failure of the normal supply.
•
The 48 VDC panic output from an F-Drive R12 Driver to sense failure of the power to the F-
Drive R12.
Connect this circuit to the "Sense" input terminal.
2. "Maintain" input: a circuit with a changeover relay that switches to a battery-backed supply
that provides power to the fixture when the normal mains supply fails. Connect this circuit to
the "Maintain" input terminal.
"Sense" detects when power is lost and forces the fixture to a full-on state, powered by the
emergency supply through the maintained input. Control of the fixture will not be available until
the sense input has been restored.
