1. Ensure the LED load’s rated power is greater than or equal to the power output of this emergency LED driver (7W). 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 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 luminaires 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 array when
operating from the AC driver.
3. Ensure the output current of the LED driver does not exceed 1.6 Amps. This is the current into the blue wire.
4. Ensure the LED fixture’s rated efficacy is equal to or greater than 65 lm / watt. This is to ensure that the LED fixture can be mounted at or below the maximum rated
mounting height of 25.8 ft.
5. Ensure there will be sufficient light output in the end application. Estimate the emergency egress lighting illumination levels by doing the following.
You can estimate the egress lighting illumination levels by doing the following:
a. Find the efficacy of the LED lighting fixture. Luminaire efficacy information can be found at the Design Lights Consortium websit (http://www. designlights.org),
Energy Star - Certified Products - product finder website (http://www.energystar.gov/productfinder/) or given by the luminaire manufacturer on product catalog
specification sheets. The LED fixture efficacy will be given in lumens per watt (lm/w).
b. Lumens can be calculated by multiplying the output power of the emergency LED driver (7W) 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.
CAUTION: SUPPLY AC POWER TO THE EMERGENCY DRIVER BEFORE JOINING BOTH CONVERTER CONNECTOR RED WIRES
INSTALLATION
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 4 checks to determine if your luminaire is eligible for use with this LED battery pack.
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 - 4 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. Disconnect AC power to the LED lighting fixture. Remove lens and ballast channel cover from LED fixture if applicable. (see illustrations 2 & 4)
Step 2. Using the 2 supplied screws, mount the LED emergency driver. The lighting fixture instructions might provide suggestions on the driver mounting location.
Step 3. Test switch/indicator light can be mounted directly to a fixture surface thru a 1/2 inch diameter hole. Once nut is tightened, slip UL switch cover over wires,
pushing cover against fixture surface completely covering switch, then affix ty-wrap over wires against cover to secure. Switch should be visible once fixture is
installed. (see illustration 1 & 4)
Step 4. Test switch/indicator light can also be installed onto a driver channel cover through a 7/8 inch diameter hole (see illustrations 2 & 3.) Trim plastic tube to desired
length, affix UL switch cover as shown and place into tube. Affix both the small bushing and the large bushing onto the plastic tube as shown. Connect tie wrap
onto wires, tighten and insert into channel. Switch should be visible once fixture is installed.
