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.
4. DO NOT USE OUTDOORS. The I-462 is for use with grounded, UL Listed, damp location rated, indoor fixtures. Do not use in heated air outlets or hazardous locations.
5. The I-462 requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused A.C. lead.
6. When the I-462 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-462 and A.C. ballast must be on the same panel board.
7. Do not mount near gas or electric heaters.
8. The I-462 should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.
9. The I-462 mounts on top of the fixture or adjacent to the fixture on an optional T-bar mounting bracket.
10. The I-462 will cold strike and operate two 2′-4′ T5 fluorescent lamps up to 54W, or two 13W-42W compact fluo- rescent lamps.
11. The I-462 operates lamps as follows: Two 2′-4′ T5 fluorescent lamps up to 54W, or two 13W-57W compact lamps for 90 minutes.
12. Suitable for use in damp locations.
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.

CAUTION: Before installing, make certain the A.C. power is off and the I-462 unit connector is disconnected.
1. MOUNTING THE I-462
Remove the ballast channel cover. Mount the I-462 on the fixture top in a position that does not interfere with the existing A.C.
ballast or any other hardware. Extend the flex conduit to a convenient location on top of the fixture and punch a the wires and flex connector down through the hole in the fixture and secure in place with the flex connector nut. An optional T-bar mounting kit is available to mount the I-462 above the ceiling tile adjacent to the emergency fixture. To order the optional T-bar mounting kit (part number TBMK-160) contact Customer Service.
When used with ceiling mounted downlight fixtures, the I-462 should be mounted on the fixture above the ceiling or on the
optional T-bar mounting kit. The flex conduit should be wired into the ballast/lamp compartment or to an electrical junction box on the fixture which allows access to the ballast/lamp connections. Refer to Illustration 2 for typical mounting.
When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between the battery
pack and the lamp(s).
CAUTION: Properly secure the I-462 in the ceiling grid to insure compliance with local, state, and federal guidelines
regarding ceiling mounted equipment.
2. 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.
3. INSTALLING THE CHARGE INDICATOR
Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast cover and drill or punch a 7/8″ hole
1
(
/2″ knockout). Insert the 7/8″ bushing into the hole. Push the plastic tube through the bushing. Disconnect the leads from the LED housing and route the leads down the plastic tube. Reconnect the leads to the housing, observing the proper polarity (Red/Black or Red lead w/connector to positive (+) red tab). 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 Charge Indicator is within ¼″ of the fixture lens. The Charge Indicator must be visible after installation. Refer to Illustration 1.
Ceiling-Mounted Downlight Fixture – Select a convenient location on the side of the fixture so the Charge Indicator can be
seen after installation. Allow for proper clearance inside the fixture and drill or punch a 1/2″ hole. Disconnect the leads from the LED housing. Push the LED housing into the 1/2″ hole until it is firmly locked in place. Reconnect the leads, observing the proper polarity (Red/Black or Red lead w/connector to positive (+) red tab). Refer to Illustration 2. For remote mounting the charge indicator and test switch, the optional RTK accessory kit can be ordered.

/8″ hole. Feed
4. INSTALLING THE TEST SWITCH
The test switch should be mounted on the ballast channel cover of a recessed troffer, or on the side of a strip fixture, preferably
adjacent to the charge indicator. Drill or punch a 1/2″ mounting hole. Refer to Illustration 2.
5. WIRING THE A.C. INPUT
A. The I-462 requires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage lead and cap the
unused lead.
B. When the I-462 is used with a switched fixture, the A.C. input to the I-462 must be connected ahead of the fixture switch.
Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.
C. When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per NEC, the I-462 and
A.C. ballast must be on the same panel board.

6. 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.
7. COMPLETING INSTALLATION
When the installation is complete, switch the A.C. power on and join the I-462 unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-462 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-462 senses the A.C. power failure and automatically switches to the Emergency Mode. One or two lamps are illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power is restored, the I-462 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-462 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 or two lamps should operate at full or reduced output, depending on your configuration.
1
Annually – Insure that the Charge Indicator light is illuminated. Conduct a full 1 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.
