6. WIRINg ThE A.C. INPUT

A. The

ILB-1826 and LED driver must be on the same branch circuit.

B. The

ILB-1826 requires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage

lead and cap the unused lead.

C. When the

ILB-1826 is used with a switched fixture, the A.C. input to the ILB-1826 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

Test Switch and Charge Indicator. Annotate Replacement Label

with identical manufacturer part number(s). The Caution and the Replacement 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

ILB-1826 unit connector.

OPERATION

Normal Mode – A.C. power is present. The LED driver operates the LED light array(s) as intended. The ILB-1826 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 ILB-1826 senses the A.C. power failure and automatically switches to

the Emergency Mode. One or multiple LED arrays are illuminated, for a minimum of 90 minutes. When the A.C. power is

restored, the

ILB-1826 switches the system back to the Normal Mode and resumes battery charging. See page 1 of the

Instruction manual.

TESTING & MAINTENANCE

Pressing the

Test Switch turns off the light on the Charge Indicator and forces the unit into emergency mode, inter-

rupting power to the designated LED driver. The LED array is now being lit by the

ILB-1826 unit. After releasing the Test

Switch, 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 30-second discharge test. Allow a 24
hour charge before conducting a 90 minute test.
The

ILB-1826 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. At least one LED array should operate at reduced output.
Annually – Insure that the Charge Indicator is illuminated. Conduct a full 90 minute 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.
