See below for operation of the self-test function.

We recommend, on commissioning the installation, a minimum charge period of 24 hours
before carrying out an emergency duration test.

If the batteries have been left in a discharged state for an extended period, we recommend
that one or more charge and discharge cycles are completed which should help to restore
the battery capacity.

SELF-TEST FUNCTION

This product is programmed to carry out its own self-test function according to the
following programme:

24 hours after first power-on 3-hour duration test

then every 28 days 30 second monthly function test

and every 52 weeks 3-hour duration test

Following self-tests, the unit will revert into charging mode, and any faults will be indicated
by the bi-colour LED indicator as follows:

LED Indicator Status

Solid green Normal conditions / charging / test successful

1 red flash Battery fault

2 red flashes Lamp fault

3 red flashes Duration test failure

NB: to clear a fault indication once a fault condition is rectified, either disconnect and restore
power to the unit or hold the test button for 10 seconds.

Tests can also be initiated manually as follows:

Test button Green LED Status

Short press Off Emergency mode while test button held in

Press for approx. 5
seconds

Press for approx. 7
seconds

Press for approx. 10
seconds

Slow flash Emergency mode for 30 seconds (monthly

TESTING FOR EMERGENCY LUMINAIRES

Recommended routine test procedure in accordance with BS5266:

• Daily check – check status of bi-colour LED indicator

• Monthly functional test – the luminaire will perform this function without any action from
the user. Alternatively, simulate a mains supply failure for approx. 30 seconds by
operation of key switch, switching off circuit breaker or using test button. Ensure normal
supply is restored after test and check status of bi-colour LED indicator

• Annual three-hour duration test – the luminaire will perform this function without any
action from the user. Alternatively, simulate a mains supply failure for three-hour
continuous test by operation of key switch, switching off circuit breaker or using test
button. Ensure normal supply is restored after test and check status of bi-colour LED
indicator

If the luminaire fails any of the above tests, please contact a qualified electrician. Results
should be recorded, even when obtained via the self-test function. See below for test record
sheet.
