Preparation
1.
The battery must be connected before installation. Connect the red wire from the battery into the terminal
marked ‘RED +’ on the Conversion Unit.
2. Feed the assembly carefully into the long fireproof bag. Batteries first, followed by the conversion unit and
finally the low voltage transformer. Ensure that the two mains cables, the low voltage output and the LED
indicator extend out the end of the bag, and secure with a cable tie.
3. Cable ties should be tied around the long fireproof bag long fireproof bag to hold each component of the
train firmly in place.
4. The end of the assembly should be tied close to the transformer in order to leave sufficient cable length for
connection to the mains supply, downlight and to allow the LED indicator to be fixed in position.
5. The Low Voltage Emergency Pack is now ready for installation.

7.
Cut the downlight cut-out hole in the required position. For cut-out size refer to the installation instructions
or packaging of the selected downlight. A correctly packed LV emergency pack should fit through a 73mm
diameter hole.
Insert the Low Voltage Emergency Pack through the downlight cut-out in the ceiling.
Wiring
Non-Maintained Wiring (Light Off Continuous):
8. Position the Low Voltage Emergency Pack away from the downlight and ensure that it is not covered by
insulation or any other material. The Low Voltage Emergency Pack must be at least 75mm from the edge of
the downlight. Ensure that all the cables are well away from the downlight.
9. Connect the unswitched permanent live feed to the three core cable marked ‘Unswitched Permanent Supply’.
10. For non-maintained operation do not connect the two core cable marked ‘Maintained Emergency’. Wrap the
live and neutral in two layers of insulation tape.
11. To fit the charge indicator LED, drill a 5mm hole at a minimum distance of 25mm from the downlight to be
used. Remove the black surround from the LED and push in from the ceiling side. Gently push the LED into
the hole from the ceiling void until the tip is visible from beneath.
12. Connect the lamp output wires marked ‘Output to 12V’ to the lampholder on the downlight. Insert the lamp
into the lamp holder and fit into the downlight.

14. Connect the unswitched permanent live feed to the three core cable marked ‘Unswitched Permanent Supply’.
15. Connect the switched mains supply to the two core cable marked ‘Maintained Emergency’, ‘blue wire’ to the
neutral and the ‘brown wire’ to the switched live.
16. To fit the charge indicator LED, drill a 5mm hole at a minimum distance of 25mm from the downlight to be
used. Remove the black surround from the LED and push in from the ceiling side. Gently push the LED into

Testing
After connecting the permanent as well as the switched supply (if required) mains supply check the following:
20. The LED is illuminated. This indicates that the permanent mains supply is present and that the charger circuit
is working correctly.
21. The lamp will light under emergency conditions, by removing the unswitched mains supply.
22. The lamp will light in maintained condition by switching the switched supply.
23. The unit should be left on charge for a minimum of 24 hours before testing. Once this unit is charged it must
be connected at all times
24. To simulate normal mains supply failure, isolate the unswitched mains supply to the fitting, or use test switches
if installed.
When the unit no longer meets its rated duration of operation the battery pack must be replaced
with a battery of the same type, voltage and Amp-hour rating.
