EMERGENCY LIGHTING EQUIPMENT

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 – Connect the battery to the unit before applying A.C. power.

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

3. 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 discon
necting the unit connector. In addition, the circuit board should be mounted so that no live parts are accessible
dur

ing routine maintenance or relamping.

4. 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.

5. The I-42-L is for use with grounded, UL Listed, indoor fixtures. The acceptability of the combination must be
determined by Underwriters Laboratories. Refer to the Engineering Considerations section for proper installation.

6. T

he I-42-L and A.C. ballast must be on the same branch circuit.

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

8. Do not mount near gas or electric heaters.

9. The I-42-L should be mounted in locations and at heights where it will not readily be subjected to tampering by
unauthorized personnel.

10. The I-42-L 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.

11. The I-42-L is for use with unusually shaped fluorescent fixtures such as wall packs, sconces, and recessed
stair fixtures.

12. 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.

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

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

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

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

ENGINEERING CONSIDERATIONS

Use – For use only in complete equipment or final applications where the acceptability of the combination is deter-

mined by Underwriters Laboratories, Inc.

These components have been judged on the basis of the required spacings in the Standard for Emergency Lighting

and Power Equipment UL 924, Sec. 29, which covers the end use product for which the component was designed.

CONDITIONS OF ACCEPTABILITY

1. Installed in a suitable ultimate enclosure.

2. Used with marked electrical ratings.

3. Provide with proper spacing between live parts and enclosure and/or adjacent devices.

4. Factory wired only (terminations not suitable for field wiring).

5. Temperature tests may have to be repeated where battery temperature exceeds 50° C.

6. Mounted within the end-use product such that the battery is secured and the test switch operates properly
when the end product is fully assembled.

7. End-use products employing one or more of these devices are to be marked in accordance with the Standard
for Emergency Lighting and Power Equipment, UL 924.

INSTALLATION INSTRUCTIONS

CAUTION: Before installing, make certain the A.C. power is off and the I-42-L unit connector is disconnected.

1. LAMPS OPERATED

Refer to the chart below for the type of lamp(s) operated and the number of lamps to be operated in the emergency mode.

If you have any questions regarding specific lamps, contact customer service.

The 6″ violet leads provide the lamp selection option. The unit is shipped from the factory with the leads

disconnected and capped. When used with particular lamp types, violet leads should be connected to one anoth­er. Refer to chart for lamp selection options.

2. MOUNTING THE I-42-L AND BATTERY

Mount the I-42-L 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). Mount the I-42-L using the mounting holes provided. The insulating barrier should be
mounted against the fixture wall. Then the main circuit board can be mounted leaving a space between the board
and the mounting barrier as shown in Illustration 1. The circuit board should be placed so that no live parts are ac­cessible during routine maintenance or relamping.

The battery should be at least 1/2″ from the A.C. ballast and other heat sources. Since heat rises, try to mount the

battery as low as possible. CAUTION – Connect the battery to the unit before applying A.C. power.

INSURE WIRING IS IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE AND LOCAL REGULATIONS.

OBSERVE PROPER
POLARITY

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 1/2″ hole. Remove the nut from the TBTS. Push the TBTS housing into the

1

/2″ 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). NOTE: For proper operation, use only the test accessories provided with the unit.

See Page 1 of the Instruction Manual.

4. WIRING

A. The I-42-L and A.C. ballast must be on the same branch circuit.

B. The I-42-L requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when used with
switched fixtures, the I-42-L input must be wired ahead of the switch.
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.

6. COMPLETING INSTALLATION

A. When the installation is complete, switch the A.C. power on and join the I-42-L unit connector.

B. Replace the ballast cover, fixture lens and other fixture hardware.

OPERATION

Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-42-L is in
the standby charging mode. The TBTS will be lit providing a visual indication that the battery is being charged.

Emergency Mode – The A.C. power fails. The I-42-L senses the A.C. power failure and automatically switches to the
Emergency Mode. One lamp or two lamps are illuminated, at reduced output, for a minimum of 90 minutes. When the
A.C. power is restored, the I-42-L switches the system back to the Normal Mode and resumes battery charging. See
page 1 of the Instruction Manual.

TESTING & MAINTENANCE

Pressing the red lens on the TBTS turns off the light on the TBTS and forces the unit into emergency mode, interrupting
power to the designated A.C. ballast. The emergency lamp is now being lit by the I-42-L unit. After releasing the TBTS,
the fixture returns to normal operation after a momentary delay. To simulate a “BLACK OUT” use the circuit breaker to
turn off A.C. power.

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

The I-42-L 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 TBTS light is illuminated. Conduct a 30 second discharge test by depressing the TBTS. One
lamp or two lamps should operate at reduced output.

Annually – Insure that the TBTS light is illuminated. Conduct a full 1½ 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.
