5. WIRING THE A.C. INPUT
A. The I-880 and A.C. ballast must be on the same branch circuit.
B. The I-880 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 I-880 is used with a switched fixture, the A.C. input to the I-880 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 ser-
vice the fixture.
8. COMPLETING INSTALLATION
When the installation is complete, switch the A.C. power on and join the I-880 unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-880 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-880 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-880 switches the system back to the Normal Mode and resumes battery charging. See page 1
of the Instruction Manual.
TESTING & MAINTENANCE
Pressing the red lens on the TBTS turns off the light on the TBTS and forces the unit into emergency mode, inter-
rupting power to the designated A.C. ballast. The emergency lamp is now being lit by the I-880 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 press the TBTS to conduct a short discharge test.
Allow a 24 hour charge before conducting a one hour test.
The
I-880 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 or
two lamps should operate at reduced output.
Annually – Insure that the TBTS is illuminated. Conduct a full 1
1 /
2
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.”
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
