5. Operation
The EUR70R exit sign operates automatically:
- AC Power Present: When normal AC power is supplied, the LED 'EXIT' legend will be illuminated, and the internal battery will be charged and maintained by the solid-state charger.
- AC Power Failure: In the event of an AC power interruption, the unit will automatically switch to battery power, illuminating the 'EXIT' legend for a minimum duration as required by safety codes. The low-voltage disconnect feature prevents deep discharge of the battery.
- AC Power Restored: When AC power is restored, the unit will automatically switch back to AC operation, and the battery will begin recharging.
6. Maintenance
Regular maintenance ensures the reliable operation of your exit sign.
- Monthly Test: Press and hold the test button (if present) for 30 seconds. The 'EXIT' legend should remain illuminated. Release the button; the legend should return to normal operation.
- Annual Test: Disconnect AC power to the unit for 90 minutes. The 'EXIT' legend should remain illuminated for the entire duration. Reconnect AC power after the test.
- Cleaning: Clean the sign's surface with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: The sealed lead calcium battery has a typical lifespan. If the unit fails to meet the required emergency illumination duration during testing, the battery may need replacement. This should be performed by qualified service personnel.
