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 emergency driver.
6. Ensure there will be sufficient light output in the end application. Estimate the egress lighting
illumination levels by doing the following:
a. Find the efficacy of the LED load. This can be given by the luminaire manufacture. This
number will be given in lumens per watt (lm/w). It is the installer’s responsibility to
validate the luminaire manufacturer’s efficacy data. This can be accomplished by direct
measurement, by review of independent 3rd party test data (UL, ETL, etc.), accessing
a public database of 3rd party data (such as Design Lights Consortium,
www.designlights.org), or other comparable means.
b. Lumens can be calculated by multiplying the emergency mode power of the LED driver
by the efficacy of the LED load. In many cases the actual lumen output in emergency
mode will be greater than this calculation gives, however it will provide a good estimate
for beginning the lighting design of the system.
c. Using the results of this calculation and industry standard lighting design tools,
calculate the anticipated illumination levels in the path of egress.

NOTE:
This product has been designed to reliably interface with a wide selection of LED modules and
is electrically compatible with every simple LED array that meets criteria 1 and 5 above. However,
compatibility cannot be guaranteed with all current and future LED systems. Compatibility testing of
the end-use system is suggested. Please contact the factory with any questions.
NOTE:
After installation, it will be necessary to measure the egress lighting illumination levels to
ensure it complies with national, state, and local code requirements.
Installation of this emergency LED driver will vary based on the luminaire type, however, generally
follow these steps:
STEP 1: INSTALLING EMERGENCY DRIVER
Disconnect AC power from the LED luminaire.
Mount the emergency LED driver along with the battery pack(s) by the mounting tabs. The
luminaire’s installation instructions may provide guidance on the recommended mounting
location.
Emergency driver & battery pack assembly (battery, wires & fuse) must be completely installed
inside of a UL 1598 / CSA C22.2 no. 250 (Listed Luminaire) enclosure, or a UL 924 / CSA
C22.2 no. 141 (Listed Emergency Lighting) enclosure.
No open holes should be left within an
enclosure of wiring or electrical components.
The emergency driver and the battery pack(s), including fuses, as a system may be remote
mounted from the luminaire, when installed within a UL 1598 / CSA C22.2 no. 250 (Listed
Luminaire) enclosure, or a UL 924 / CSA C22.2 no. 141 (Listed Emergency Lighting)
enclosure
Please refer to the specification sheet for the maximum recommended remote
mounting distance. Remote mount wiring must be in accordance with the National Electrical
Code/Canadian Electrical Code and with local installation requirements.
