INSTRUCTION MANUAL

IMPORTANT SAFEGUARDS

When using electrical equipment, basic safety precautions should always be followed, including the following:

READ AND FOLLOW ALL SAFETY INSTRUCTIONS

1. CAUTION – To prevent electrical shock, do not mate unit connector until installation is complete and A.C.
power is supplied to the unit.

2. CAUTION – This fixture provides more than one power supply output source. To reduce the risk of electrical
shock, disconnect both normal and emergency sources by turning off the A.C. branch circuit and by discon­necting the unit connector.

3. CAUTION – This is a sealed unit. The integral, high temperature Ni-Cad battery is not replaceable. Replace
the entire unit when necessary and recycle or dispose of the nickel-cadmium battery properly.

4. DO NOT USE OUTDOORS. The I-42-EM-B is for use with grounded, UL Listed, damp location rated, indoor
fixtures. Not for use in heated air outlets or hazardous locations.

5. The I-42-EM-B requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused
A.C. lead.

6. When the I-42-EM-B is installed on the same branch circuit, refer to Illustration 3, Figures A and B for input
wiring. When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per
NEC, the I-42-EM-B and A.C. ballast must be on the same panel board.

7. Do not mount near gas or electric heaters.

8. The I-42-EM-B should be mounted in locations and at heights where it will not readily be subjected to tamper-
ing by unauthorized personnel.

9. The I-42-EM-B will cold strike and operate one 10W through 42W, or two 10W through 18W, 4-pin Rapid Start
compact fluorescent lamps. Contact customer service for additional lamp usage.

10. The I-42-EM-B is compatible with most electronic A.C. ballasts (including multiple lamps) as follows:
Electronic ballasts – one or two lamp emergency operation.

11. Suitable for use in damp locations and in enclosed and gasketed fixtures.

12. When used in conjunction with enclosed and gasketed fixtures, the I-42-EM-B is suitable for mounting in the
ballast compartment only.

13. For use in 0° C minimum, 50° C maximum ambient temperatures.

14. The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.

15. Do not use this equipment for other than intended use.

16. Install in accordance with the National Electrical Code and local regulations.

17. Installation and servicing should be performed by qualified personnel.

18. Lighting fixture manufacturers, electricians and end users need to ensure product system compatibility before
final installation.

2. MOUNTING THE I-42-EM-B

Mount the I-42-EM-B in the ballast channel or enclosed wireway so the wire leads are not exposed, at least ½″

away from the A.C. ballast(s). Refer to Illustration 1. For mounting the I-42-EM-B on top of the fixture, use the
optional TMK-80 mounting accessory for covering the wires that enter the fixture. Refer to Illustration 2.

When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between

the battery pack and the lamp(s).

3. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)

Select a convenient location on the side of the fixture so that the TBTS can be seen after installation. Allow for

proper clearance and drill or punch a ½″ hole. Remove the nut from the TBTS. Push the TBTS housing into the
½″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or Red w/tag to

Red, and White/Red to White).

4. WIRING

A. When the I-42-EM-B is installed on the same branch circuit, refer to Illustration 3, Figures A and B for

input wiring. When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring.
Per NEC, the I-42-EM-B and A.C. ballast must be on the same panel board.

B. The I-42-EM-B requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when
used with switched fixtures, the I-42-EM-B input must be wired ahead of the switch. Refer to Illustration 3
for switched and unswitched fixture wiring diagrams.
C. Refer to the wiring diagrams on the back page for the proper wiring. For wiring diagrams of ballasts not shown,

consult our Customer Service.

5. LABELS

Attach the appropriate labels adjacent to the TBTS. Annotate Re-lamping label for lamp type and wattage. The

Caution and the Re-lamping labels must be on the fixture in a readily visible location to anyone attempting to ser­vice the fixture.
