Commissioning:
Once the luminaire has been installed in line with the manufacturer’s
recommendations, the battery should be allowed to charge for a
minimum period of 24 hours before testing for its rated duration. If it is
anticipated that the un-switched supply may be interrupted, it is imperative
that commissioning is delayed until the supply is stable. Repeated starting
attempts in the emergency mode with an uncharged battery pack will
result in premature lamp failure. If the luminaire has been stored for a
number of months, it may be necessary to repeat the charge/discharge
process several times to re-condition the battery.
After successful commissioning, the battery should be marked with the date of
commission.
Routine test and inspection should be performed in accordance with EN50172
or otherwise local legislation. Short discharge periods of around 5 – 10
minutes each month for the purposes of inspection will not adversely affect
One-LUX batteries and should be considered as a maintenance exercise for the
battery. Regular full discharge cycles will adversely affect the design life of the
battery.
