cutoff switch must also be closed.
Automatic operational life tests:
The first operational life test carried out automatically by the emergency light unit takes place at
random within a period of 5 to 28 days after the light fitting has been setup. 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.
A complete interruption of the energy supply to the emergency light unit occurs when the outage of the
power supply exceeds the specified nominal operating time for the emergency light.
Reconnecting the power supply to the emergency light unit after a complete interruption will lead to a
new setup procedure of the emergency light with a subsequent operational life test between 5 and 28
days later.
Should a fault in the battery capacity be indicated before a complete interruption of the power supply to
the emergency light unit, a operational life test will be carried out within 24 hours of reconnection to the
power supply.
If the prerequisites stated above for carrying out an automatic operational life test are not satisfied, the
test will be deferred until these requirements are fulfilled.
Automatic operational life tests that could not be completed successfully will be repeated once after 60
hours, subject to the same prerequisites stated above.
Manual operational life tests:
Operational life tests can be triggered manually in 3 ways:
1. By switching the power supply off and on at the L1 terminal.
2. By switching the supply on and off at the L1` terminal.
Switch the power supply at the L1 terminal resp. the supply at L1' terminal off and on again 5 times.
Leave at least 2 seconds between each switch.
In both cases, the sequence of switches must be completed within 60 seconds.
Under the above mentioned preconditions, after a correctly performed switching sequence at L1'
terminal, an operational life test is immediately initiated.
If the switching sequence is correctly carried out on L1 terminal, an operational life test is initiated after
the time that is required to fully charge the battery after the switching sequence.
If the switch sequence has not been carried out correctly, or the aforementioned requirements have
not been satisfied, the operational life test will not be conducted.
If there was an error in the switching procedure, the entire switch sequence can only be repeated after
60 seconds have elapsed.
The points at which regular operational life tests are carried out are not affected by conducting a
manual test using either of these methods.
3. By means of disconnecting and reconnecting the battery:
Open and close the lid of the battery box twice within a 60-second period. Opening and closing the
case must occur within 10 seconds of each other.
If this procedure is done correctly, immediately after the battery box is closed for the second time, the
signal LED will display an acknowledgement light. The five-second long red-green acknowledgement
light confirms that a operational life test will be conducted 12 hours later.
Should a battery capacity fault be present when the acknowledgement light is displayed, more
operational life tests will then be carried out at 52 week intervals. If no fault was detected in the battery
capacity, the interval until the next regular operational life test is unaffected.

During the functionality and operational life tests, the light fitting will switch on even if it
was previously switched off!
2.3 Ascertainable faults and reset of the display
LED failure
If a fault in the LED is detected by the emergency light unit during a functionality test, the LEDs will be
switched off and the fault will be indicated by a permanent red light on the signal LED.
An LED fault will be reset if a functionality test produces a positive result or if the emergency light unit
is completely separated from the battery and power supply.
