NOTE: After installing the charging indicator light and
test switch, mark each with appropriate label.
6. After installation is complete, supply AC power to the
emergency ballast and join the battery connector.
7. A short-term discharge test may be conducted after the
emergency ballast has been charging for one hour. Charge
for 24 hours before conducting a long-term discharge test.
Refer to OPERATION.
OPERATION
When AC power is applied, the charging indicator
light is illuminated, indicating that the battery is being
charged. When power fails, the emergency ballast automat-
ically switches to emergency power, operating 17W-40W
lamps at reduced illumination for at least 90 minutes
MAINTENANCE
Although no routine maintenance is required to keep the
emergency ballast functional, it should be checked peridical-
ly to ensure that it is working. The following schedule is rec-
ommended:
1. Visually inspect the charging indicator light monthly. It
should be illuminated.
2. Test the emergency operation of the fixture at 30-day
intervals for a minimum of 30 seconds. One lamp should
operate at reduced illumination.
3. Conduct a 90-minute dischare test once a year, either on
or two lamps should operate at reduced illumination for at
least 90 minutes.
