6. Functions
6.2 Testing
Commissioning test
A full commissioning test is carried out automatically after permanent con-
nection of the supply for 5 days. The easy commissioning feature will set the
initial test day and time to ensure random testing of units.
Functional test
Functional tests are carried out for 5 seconds on a weekly basis under the
control of the Micro controller. Initiation and timing of these tests is set dur-
ing the commissioning of the luminaire.
Duration test
A full duration test is carried out yearly to check the capacity of the batteries.
For a full description of commissioning and test features please refer to
application notes.
Test switch
Test switch is integrated in the bezel. This can be used to to:
• Initiate a 5 seconds function test:
press 200 ms < T < 1 s
• Execute function test as long as switch pressed: press > 1 s
• Reset selftest timer (adjust local timing):
press > 10 s
To initiate a test use a suitable tool, refer to drawing below.
Note: Press test switch carefully to avoid damaging it.
Timer reset functionality
The timer for function and duration test can be set to a particular time of the
day by either pressing the test switch for longer than 10 seconds or cycling
the unswitched line supply 5 times within 1 minute. The timer adjustment
will enable the test start time to be defined manually at time in day when the
timer was reset. It will also disable the adaptive test algorithm thereby forc-
ing the unit to perform the test at the same time rather than it being defined
by the adaptive algorithm. This function will only work provided the interval
time is greater than zero (automatic test mode enabled). The delay timer
6.1 Status indication
System status is indicated by a bi-colour LED. The indication LED is integra-
ted in the bezel.

Rest mode
Rest mode can be initiated by applying a short pulse of between 9.5 V

in amplitude for a period of between 150 ms and 1.0 s. This should
be applied to terminals marked Rest after the mains supply has been discon-
nected and whilst the module is in emergency operation. Terminals are not
sensitive to polarity.
After a mains reset the EM R2A ST exits the rest mode. The EM R2A ST sup-
ports the re-light function.
