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-320 unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-320 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-320 senses the A.C. power failure and automatically switches to the
Emergency Mode. One lamp is illuminated, at reduced output, for a minimum of 90 minutes. When the A.C.
power is restored, the I-320 switches the system back to the Normal Mode and resumes battery charging. See page 1
of the Instruction Manual.
TESTING & MAINTENANCE
Pressing and holding the TBTS for a minimum of five seconds turns off the light on the TBTS and forces the unit into
emergency mode, interrupting power to the designated A.C. ballast. The emergency lamp is now being lit by the I-320 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 and hold the TBTS for a minimum of five sec-
onds to conduct a short discharge test. Allow a 24 hour charge before conducting a one hour test.
The
I-320 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 lamp
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.
