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. Re-
place the entire unit when necessary and recycle or dispose of the nickel-cadmium battery properly.

FLUORESCENT EMERGENCY BALLAST

4. DO NOT USE OUTDOORS. The I-26-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-26-EM-B requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused
A.C. lead.

6. Do not mount near gas or electric heaters.

7. The I-26-EM-B should be mounted in locations and at heights where it will not readily be subjected to tamper-
ing by unauthorized personnel.

8. The I-26-EM-B is designed to cold strike and operate one 18W–26W, quad tube compact fluorescent lamp,
two-pin base including integral starter, with a single lampholder per lamp.

9. The I-26-EM-B is for use in fluorescent downlight fixtures.

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

11. When used in conjunction with enclosed and gasketed fixtures, the I-26-EM-B is suitable for mounting in the
ballast compartment only.

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

13. The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition, void
warranty, and result in non-compliance with UL specifications.

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

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

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

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

CAUTION: Before installing, make certain the A.C. power is off and the
I-26-EM-B unit connector is disconnected.

1. MOUNTING THE I-26-EM-B

Mount the I-26-EM-B in the ballast channel or enclosed wireway so the wire leads are not exposed, at least 1/2″

away from the A.C. ballast(s). Refer to illustrations 1 and 2.

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

the battery pack and the lamp.

2. WIRING

Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s), ballast and I-26-EM-B. Install

in accordance with the National Electrical Code and local regulations. For additional wiring diagrams not shown,
consult Customer Service.

3. INSTALLING THE CHARGE INDICATOR

Downlight Fixture– Select a convenient location on the fixture so that the Charge Indicator can be seen after in-

stallation. Allow for proper clearance and drill or punch a 1/2″ mounting hole. Disconnect the leads from the Charge
Indicator. Push the Charge Indicator into the 1/2″ hole until it is firmly locked into place. Reconnect the leads,
observing proper polarity (Red/Black or Red lead w/connector to positive (+) red tab). Make certain all leads are
enclosed in an appropriate wireway. Refer to Illustrations 1 and 2.

NOTE: To ensure proper operation, use only the test accessories provided with the unit. See Page 1 of the Instruc-

tion Manual.

4. INSTALLING THE TEST SWITCH

Downlight Fixture– The test switch should be mounted on the fixture to allow access to authorized personnel. Drill

or punch a 1/2″ mounting hole. Make certain all leads are enclosed in an appropriate wireway. Refer to Illustration 1.

NOTE: Position the Charge Indicator so that
it can be seen after installation.

OBSERVE PROPER POLARITY

5. LABELS

Attach the appropriate labels adjacent to the Test Switch and Charge Indicator. 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.

6. COMPLETING INSTALLATION

A. When the wiring is complete, the A.C. power is to be turned on permanently, join the unit connector.

B. Replace the ballast cover, fixture lens and other fixture hardware.
C. Refer to the “Operation” section below for proper operation.

OPERATION

General —The I-26-EM-B is a compact fluorescent emergency ballast. The I-26-EM-B is to be used with U.L. Listed
fluorescent fixtures. When used with fluorescent downlight fixtures, the I-26-EM-B will wire in conjunction with the exist­ing lamp(s) to provide the emergency function.

Normal Mode – A.C. power is present. The A.C. ballast(s) operate the fluorescent lamp(s) as intended. The
I-26-EM-B is in the standby charging mode. The Charge Indicator will be lit providing a visual indication that

the battery is being charged.

Emergency Mode – The A.C. power fails. The I-26-EM-B senses the A.C. power failure and automatically switches to
the Emergency Mode. One lamp is illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power
is restored, the I-26-EM-B switches the system back to the Normal Mode and resumes battery charging. See page 1 of
the Instruction Manual.

TESTING & MAINTENANCE

Initial Testing – Allow the unit to charge approximately 1 hour, then conduct a short discharge test. Allow a 24 hour
charge before conducting a one hour test.

The I-26-EM-B is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety
Code, outlines the following schedule:

Monthly – Insure that the Charge Indicator light is illuminated. Conduct a 30 second discharge test by depressing the
Test Switch. One lamp should operate at reduced output.

Annually – Insure that the Charge Indicator light is illuminated. Conduct a full 11/2 hour discharge test. The unit should

operate as intended for the duration of the test.

“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”

SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
