INSTALLATION

STEP 1 -
DETERMINE SUITABILITY
>
Disconnect AC power from the LED luminaire.
>
Mount the emergency LED driver by the mounting tabs using the supplied screws. The
luminaire’s installation
instructions may provide guidance on the recommended mounting location.
>
Mounting Height
: Many factors influence emergency illumination levels, such as the lamp
load selected, luminaire design, and environmental factors therefore end use verification is
necessary. For field installations, when the attached luminaire is mounted at heights greater
than 7.17ft (2.2m), the level of illumination must be measured in the end application to ensure
the requirements of NFPA 101 and local codes are satisfied.
>
Remote Mounting
: The emergency LED driver may be remote mounted from the luminaire it
enclosed and installed in accordance with the NEC. If used in conjunction with an AC driver the
allowed distance is up to half the distance the AC driver manufacturer recommends remote
mounting the AC driver from the LED load. If used without an AC driver, and remote mounting
more than 5 feet from the luminaire, please consult the factory to determine the necessary
wire gauge.
CAUTION
: Remote mounting can result in reduced power output.
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, in the luminaire specifications, or imprinted directly on the LED arrays. If multiple LED arrays are to
be driven, 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. Ensure the output current of the AC LED driver does not exceed 3.0 Amps. This is the current into the blue
wire connector.
4. 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 output power of the emergency 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.
Lumens In Emergency Mode = Lumens per Watt of Fixture * Output Power of Chosen Product
(Lumens) = (lm/W) * (W)
C. Using the results of this calculation and industry standard lighting design tools, calculate the
anticipated illumination levels in the path of egress.
This product is suitable for field installation with suitable LED loads including LED luminaires, DC voltage
driven LED replacements for fluorescent lamps and others. There are four (4) checks to determine if
your luminaire is eligible for field installation.
NOTE: This product has been designed to reliably interface with a wide selection of LED loads and is electrically
compatible with every simple LED array that meets criteria 1 and 2 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.
Make sure the necessary branch circuit wiring is available. An unswitched source of power is
required. The emergency driver must be fed from the same branch circuit as the AC driver.
Installation of this emergency LED driver will vary based on the luminaire type, however,
generally follow these steps:
