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.
An emergency battery that no longer has sufficient capacity must be replaced immediately (see
Section 6.3).
The display indicating a fault in the battery capacity can only be reset by means of a successful
operational life test.
Battery contact failure
When the electrical connection between the emergency light unit and the emergency battery is broken,
the signal LED will display a red flashing light.
A battery contact failure and its signal are automatically reset as soon as the connection between the
emergency light unit and the battery is re-established.
