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.
