5. WIRING THE A.C. INPUT
A. The
I-232 and A.C. ballast must be on the same branch circuit.
B. The
I-232 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-232 is used with a switched fixture, the A.C. input to the I-232 must be connected ahead of the
fixture switch. Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.

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-232 unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-232 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-232 senses the A.C. power failure and automatically switches to the
Emergency Mode. Two lamps are illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power
is restored, the
I-232 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-232 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. Two lamps should operate at reduced output.
Annually – Insure that the Charge Indicator light 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.
