installation.
1. Ensure the LED load’s rated power is greater than or equal to the power output of this emergency LED driver.
This is to ensure that this emergency product will not produce more power than the LED load can handle, thus
ensuring that the LED load will not be damaged when the system is in the emergency mode.
2. Verify that the forward voltage of the luminaire’s LED array is within the limits of this emergency LED driver. The
forward voltage of the LED array is commonly designated as Vf and should be found on the luminaire markings,
verify that the total forward voltage is within the limits of this product. Using a voltage meter, it may be possible
to directly measure the voltage across the LED arrays when operating from the AC driver.
3.
Consortium database. Go to the Design Lights Consortium website (http://www.designlights.org) and search for
your LED system by model name or model number. If found in the database, these products are preapproved
4. You can estimate the egress lighting illumination levels by doing the following:

beginning the lighting design of the system.
5. Determining Adequacy of Means-of-Egress Lighting Levels
6. While this model has been found compliant with the requirements of UL standard 924, it is ultimately the re-
illumination in accordance with Federal, State or local municipal requirements.
