•Provide power to the required point of installation
•The fitting is supplied with the ‘arrow up’ legend as standard. The legend may be changed if required:
the clear plastic front cover should be removed by inserting a screwdriver beside the plastic tabs top
and bottom of the clear cover (see Fig. 1) and twisting gently to lever the tabs out. Once the top and
bottom tabs are free the cover can be bent forwards and lifted out gently, taking care not to break any
of the tabs. Reverse the procedure to replace the cover

•Ensure the battery is connected via the plug and socket to the PCB
•Ensure the lamp is connected to the lamp connector on the PCB
•Refasten the cover
•Switch on and check for correct operation, ensuring the green indicator LED is illuminated
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:
1. 24 hours after first power-on
3-hour duration test
2. then every 28 days
3. 30 second monthly function test
4. and every 52 weeks
5. 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:

TESTING FOR EMERGENCY LUMINAIRES
WARRANTY
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.
This product has a warranty of 3 years (excluding battery) from date of purchase. Failure
to install this product in accordance with the current edition of the IEE Wiring Regulations
