IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions should
always be followed including the following.
READ AND FOLLOW ALL SAFETY
INSTRUCTIONS
1. Do not join converter connection until installation is complete and AC power is supplied to the emergency
driver.
2.
This product is for use with an emergency LED lighting load and supplies 7 W of constant output power to
LED lamps rated from 15-56 Vdc. Operates emergency LED load in the emergency mode for a
minimum of 90 minutes.
3. Make sure all connections are in accordance with the NEC and any local regulations.
4. To reduce the risk of electric shock, disconnect both normal and emergency power supplies and converter
connector from the emergency driver before servicing.
5. This emergency driver is suitable for factory or field installation.
6. Do not use outdoors. This product is suitable for use in damp locations where the ambient temperature is
0°C minimum, +55°C maximum. Product is not suitable for heated air outlets and wet
or hazardous locations.
7. An unswitched AC power source is required (120-277 VAC, 50/60 Hz).
8.
Do not install near gas or electric heaters.
Do not attempt to service the battery. A sealed, no-maintenance battery is used that is not field replaceable.
9.
Contact Thomas Research Products for information on service.
10. The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.
11. Do not use this product for other than intended use.
12. Servicing should be performed by qualified service personnel.
13. Equipment should be mounted in locations and at heights where it will not be subjected to tampering by
unauthorized personnel

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 5 checks to determine if your luminaire is eligible for use with this LED
battery pack.
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 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 marking's, in the luminaire specications, 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:
a. Find the efficacy of the LED lighting fixture. Luminaire efficacy information can be found at the Design Lights Consortium website (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.
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 1-5 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. 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.
Step 3. Test switch/indicator light can be mounted directly to a xture surface thru a 1/2 inch diameter hole. Once nut is tightened, slip UL switch cover over wires,
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,

pushing cover against xture surface completely covering switch, then afx ty-wrap over wires against cover to secure. Switch should be visible once xture is installed.
(see illustration 1 & 4)
afx UL switch cover as shown and place into tube. Afx 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 xture is installed.
