Testing
BS 5266 Part 8 (EN 50172) and BS EN 62034:2000
specify the statutory requirements for testing the
entire emergency lighting installation, and a copy of
this standard should be obtained.
It should be noted that, immediately after a test, the
battery might not have sufficient capacity to provide
emergency lighting cover. For this reason all tests
should be performed, where possible, at a time of
minimum risk.
Record keeping
It is a requirement of BS 5266 Part 8 (EN 50172) that
accurate records of testing are kept. Emergi-Lite have
produced an Emergency Lighting Record Log Book
designed to assist with these requirements. These are
available to order – part code YLB-EL0807.
General maintenance
Check the system has adequate ventilation. Louvres
in the door, and grilles in the rear panel must not be
obstructed. Door access must not be obstructed.
The operating environment should be free from dust,
which can accumulate inside modules.
Charger maintenance
The charger output voltage should be tested on a
monthly basis by a competent engineer to ensure it is
set correctly. Charger voltage may be affected by the
ambient temperature in the battery compartment.
Any variation in charger voltage should be noted, and,
if in doubt, contact Emergi-Lite Service Department
for advice and assistance.
Equipment should be maintained dust free and clean
to prevent premature failure.
Battery and cells maintenance and
storage
Battery storage, maintenance and handling shall be
fully carried out in line with the battery manufacturers
instructions.
The battery should be visually inspected each month
by a competent engineer to check that there is no
evidence of damaged or leaking cells. Damaged or
leaking cells require replacement. Please contact
Emergi-Lite Service Department for advice and
replacements.
Individual cell voltages should be recorded on the
record sheets provided in the manual. A digital DC
voltmeter is required for this purpose. Only record
cell voltages when the battery is fully charged, which
takes a maximum of 24 hours after a test.
Cell voltages should remain constant over the life of
the battery. Cells showing a voltage differing from
previous readings require investigation (please note
charger is temperature compensated and cell voltages
will vary with ambient room temperature changes).
Do not at any time attempt to remove or replace
cells or re-commission the system. Please contact
Emergi-Lite Service Department for advice and
assistance.
Temperature extremes severely affect battery life.
Always check and record the ambient temperature in
the battery room. The optimum temperature is 20°C.
Handling
Most cells are heavy and difficult to handle. Care
should be taken and the correct technique employed
when using manual or other lifting methods.
Explosion hazard
Recombination (sealed) cells, when operated correctly,
have negligible rates of gas evolution.
Repair/disposal
No attempt should be made to repair any cells, they
should be treated as disposable when they have
outlived their use.
Batteries must be disposed of in accordance with
current waste disposal and pollution legislation. It
is recommended that the following authorities are
contacted before any attempt is made to dispose
of cells; Environment Agency Local Office, Local
Authority Environmental Health or Waste Handling
Department.
Our Service Department is available to provide
advice regarding disposal of batteries, replacement
of batteries and re-commissioning of Central Power
Supply Systems. Please contact us for assistance.
Warranty
Failure to observe above guidance may invalidate the
Thomas and Betts warranty.
Terms and conditions of warranty apply which are
available on request.
