OPERATION
With AC power applied, the charging indicator light is illuminated, indicating that the battery is being charged.
When power fails, the emergency ballast automatically switches to emergency power, operating one lamp at
reduced illumination. When AC power is restored, the emergency ballast returns to the charging mode and delays
AC ballast operation for five seconds to prevent false-tripping of AC ballast (end-of-lamp-life) shutdown circuits. This
emergency ballast will operate 14 W through 55 W lamps for a minimum of 90 minutes.
MAINTENANCE
Although no routine maintenance is required to keep the emergency ballast functional, it should be checked
periodically to ensure that it is working. The following schedule is recommended:
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 discharge test once a year. One lamp should operate at reduced illumination for at
least 90 minutes.
