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.

LIGHTING EQUIPMENT

4. DO NOT USE OUTDOORS. The I-32 is for use with grounded, UL Listed, indoor fixtures. Not for use in heated
air outlets or hazardous locations.

5. The I-32 requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused A.C.
lead.

6. The I-32 and A.C. ballast must be on the same branch circuit.

7. Do not mount near gas or electric heaters.

8. The I-32 should be mounted in locations and at heights where it will not readily be subjected to tampering by
unauthorized personnel.

9. The I-32 will cold strike and operate one 2′ through 4′ (20-40W) instant start, rapid start, U shape or circline,
T8 through T12 or 28W T5 fluorescent lamps, including energy saving and long compacts for 90 minutes at

reduced light output.

10. The I-32 is compatible with all A.C. magnetic and electronic ballasts including multiple lamp ballasts with one
lamp operating in the emergency mode.

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

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

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

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

15. 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-32
unit connector is disconnected.

1. LAMPS OPERATED

The I-32 can be used with most 2´-4´ lamps. Refer to the chart below for the type of lamp(s) operated and the
number of lamps to be operated in emergency mode.

*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-32

Remove the ballast channel cover. Mount the I-32 in the ballast channel at least ½″ away from the A.C. ballast(s).

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

the battery pack and lamp.

3. WIRING

Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s) and ballast. Install in accordance

with the National Electrical Code and local regulations. For additional wiring diagrams consult Customer Service.

OBSERVE PROPER POLARITY

4. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)

Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast cover and drill or
punch a 7/8″ hole (½″ knockout). Insert the 7/8″ bushing into the hole. Push the plastic tube through the bushing.
Route the leads of the TBTS through the plastic tube. Connect the LED wires from the unit to the TBTS (Red/
Black or Red w/tag to Red, White/Red to White). Push the entire assembly back into the tube until the lens collar
rests against the plastic tube. The plastic tube should be adjusted so that the TBTS is within ¼″ of the fixture lens.
The TBTS must be visible after installation. Refer to Illustration 1.

Strip Fixture – Select a convenient location on the fixture so the TBTS can be seen after installation. Allow for

proper clearance inside the fixture 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, White/Red to White). Refer to Illustration 2.

C. When the I-32 is used with a switched fixture, the A.C. input to the I-32 must be connected ahead of the fixture

switch. Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.

7. 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.

8. COMPLETING INSTALLATION

When the installation is complete, switch the A.C. power on and join the I-32 unit connector.

OPERATION

Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-32 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-32 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-32 switches the system back to the Normal Mode and resumes battery charging. See page 1 of the
Instruction Manual.

TESTING & MAINTENANCE

Pressing 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-32 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 2 hours, then press the TBTS to conduct a short discharge test.
Allow a 24 hour charge before conducting a one hour test.

The I-32 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 is illuminated. Conduct a 30 second discharge test by depressing the TBTS. One lamp
should operate at reduced output.

Annually – Insure that the TBTS 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.”
