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 ser-
vice the fixture.
6. WIRING THE A.C. INPUT
A. The ILB and A.C. driver MUST be on the same branch circuit.
B. The ILB requires an unswitched A.C. power source of either 120 or 277 volts; therefore when used with
switched fixtures, the ILB input must be wired ahead of the switch. Select the proper voltage lead and cap the
unused lead.
C. Refer to the wiring diagrams on the back page for the proper wiring. For wiring diagrams not shown, consult
our customer service.
7. COMPLETING INSTALLATION
When the installation is complete, switch the A.C. power on and join the ILB unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. driver operates the LED load as intended. The ILB 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 ILB senses the A.C. power failure and automatically switches to the
Emergency Mode. One or multiple LEDs are illuminated, for a minimum of 90 minutes. When the A.C. power is restored,
the ILB 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. driver. The LED load is now being lit by the ILB 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. Allow a 24 hour
charge before conducting a one hour test.
The ILB 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. At
least one LED should operate at reduced output.
Annually – Insure that the TBTS 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.
