All further automatic operational life tests are then carried out at 52 week intervals, so long as the energy supply to the emergency light unit was not interrupted during this period.
- Page 5 Battery capacity failure If the emergency light unit detects during a operational life test that the capacity of the emergency light battery is insufficient to maintain the light fitting for the nominal operating time in the case of an emergency, the signal LED will display a red blinking light.
