EMERGENCY | ONE-LEDTM
SOLO SURFACETM | NON MAINTAINED LED EMERGENCY LUMINAIRE
For DALI Self-Test versions add ‘/DST’ to the model numbers above.
Product description
One-LED Solo SurfaceTM is a non-maintained, self-contained LED
emergency luminaire comprising an Omni-LED emergency LED driver,
rechargeable battery and a SELV LED lamp.
Its compact, surface mount enclosure is available in either square or
circular design and with either stand alone or DALI Self Test capability.
The LED lamp provides constant power output of 1.5W, so maintaining
spacing throughout rated duration. The symmetrical distribution of
light gives 8m spacing from a typical 2.5m ceiling height, when using
an open area lamp head. For the most efcient spread of light along
corridors, an optional corridor lens version is available to provide
spacing of 19m from the same height.

INSTALLATION (See page 5 for additional ‘/DST’ DALI Self-test information.)
Installation
This luminaire must be installed by a qualied and competent electrician.
Ensure the mains supply is isolated before attempting installation!
Please refer to the diagram opposite for xing details.
It should not be mounted in an external location or in areas where
temperatures below 10°C may be frequent in cold months and likewise, do not
use the luminaire in a hot environment where the temperature is maintained
at 35°C or above. In either case, the battery’s design life of 4 years will be
compromised and provision of three hour emergency duration may not be
possible when needed.
Determine the xing location, type of cable entry to the luminaire and the
direction of an escape route for lensed versions.
Cable entry points are provided at opposite sides of the gear tray, which are
suitable for use with most 20mm conduit ttings, cable glands, grommets etc.
If these are to be used, it is strongly recommended the gear tray is xed in
position beforehand.
If the supply cable is to be fed from within the ceiling, it can be guided down
through the cable entry slots in the centre of the gear tray.
Fixing
Once the location and lens orientation are determined, the circular gear tray
can be xed in position by either the two standard xing holes at the sides
(141.5mm centres) or by the BESA xing slots (50.8mm centres) in the middle
of the gear tray. Fixing point locations and the resulting direction of the escape
route are shown in the diagram opposite.
Please note, to access BESA xing locations the lamp assembly will need to
be carefully removed by squeezing the four supports inwards in pairs whilst
pulling the metal disk away from them. The lamp assembly can then be clicked
back into place once the gear tray is xed in place.
Additional xing holes and cable entry points may be added if required, but
care to avoid internal components must be observed. at all times.
Conduit cut-out guides are included on the inside of the front cover.

SOLO SURFACETM | NON MAINTAINED LED EMERGENCY LUMINAIRE
Wiring
When xed in position, prepare the supply cables with a strip length of
6mm (10mm maximum). Min/max Conductor sizes: 0.5 - 2.5 mm2.
Incoming mains connections should be made to push-wire terminals
marked ‘L’, ‘E’ and ‘N’. (and DALI bus to terminals marked ‘DA’ for /DST
versions). Please note the Earth terminal is only provided for the purpose
of terminating the incoming cable(s) and is not required for function or
safety. This product requires a permanent supply (via test key switch where
required). Once the supply connections are made, ensure the cord restraint
is xed in position as required.
Function test and commissioning
Note: This luminaire will only operate the white LED upon mains supply
failure from the internal battery supply; it cannot be operated as a standard
light source.
After installation, the red battery lead should be connected to the battery
positive and the mains supply turned on. The green indicator LED should
now be visible on the lamp head’s front bezel, showing the battery is
connected and being charged.
When the mains supply is turned off, the white LED will illuminate in
emergency mode. Reinstate the mains power, or disconnect the battery to
stop emergency operation.
Once the luminaire is ready for commissioning the battery positive should
be connected and the front cover tted into position.
The mains supply can then be instated and must remain un-interrupted for
a minimum of 24 hours for the luminaire to fully charge its internal battery.
After 24 hours, the mains supply should then be turned off and the
luminaire checked for a minimum of 3-hours duration. If successful the label
on the battery must be initialled and dated by the commissioning engineer.
Emergency Lighting ‘standard’ or ‘manual’ Test
The following minimum inspections and tests should be carried out:
Monthly
Switch off the mains power supply to the luminaire. Inspect the emergency
Switch off the mains power supply to the luminaire. Leave the unit to run for
the rated period (e.g. three hours). The light should remain operable from
the battery for the whole period. Please be aware that further inspection /
testing may be required, e.g. by risk assessment / local legislation.
Maintenance
There are no user serviceable parts within the product. The battery pack
must be replaced when the 3 hour duration is no longer achieved.
The battery is not considered user-replaceable and must be referred to
a competent engineer. Please contact one-LUX for technical support or
suitable replacement parts.
Front cover removal: If the front cover needs to be removed after tting
place, carefully press a narrow blade screwdriver through the small slots
located at opposite sides of cover’s side walls whilst pulling that side of the
cover away from the base.
Batteries and Disposal
The battery has a designed service life of 4 years and must be replaced in
a timely manner to ensure the integrity of the emergency lighting system
is maintained. In any case, the battery should be replaced with when it no
longer provides the rated duration (3 hours).
One-LUX are committed to full its obligations as a producer of batteries
used in emergency lighting applications. End-of-life batteries may either
be returned to us at the customers cost and arrangements will be made
to ensure their correct disposal. Alternatively it may be more convenient
for the customer to deliver end-of-life batteries to site(s) of authorized
treatment facilities at their cost and it will be ensured that they are accepted
back and subsequently treated to the standard required by the regulations.
Disclaimers
This product and its associated accessories have been designed
and manufactured to comply with the requirements of EN60598-
2-22 and required additional standards. Operation beyond the
parameters specied in this document and the associated standards
may result in reduced performance and ultimate premature failure,
with the warranty made void. The specier should be aware of the
environment to which this luminaire and components are used and
adhere to its specications. Please contact our Technical department
if you are in any doubt.
The unit provides reinforced insulation between the mains supply
and battery charging circuit and employs self-resetting protection
against short-circuit of battery terminals. Normal charging will
resume automatically once a fault is removed.

INSTALLATION & OPERATION of ‘/DST’ DALI Self-test versions
Automatic Testing
Once commissioned, the Solo SurfaceTM will automatically determine if it is
being used in Stand alone Self-Test mode or connected to a DALI network.
If Stand alone Self-Test is detected, it will establish randomised delay times
to ensure the next scheduled tests do not coincide with the same test of
adjacent luminaires. (See table below for details of ‘Test Delay Time’ ranges).
Subsequent routine testing will then take place according to the ‘Test Interval’
times detailed in the table below.
If the Solo SurfaceTM module detects it is installed on a DALI network, it will
congure itself according to the default DALI specication. (See table below).
It is important to note that in DALI mode, randomisation will not be set and it
will await test delay times to be congured by the DALI master.
In the event of loss of communication with the DALI master, automatic
testing will revert back to the Self-Test ‘Test Intervals’, but ‘Test Delay Times’
will remain as congured by the DALI master.

Function test and commissioning
After installation, the red battery lead should be connected to the battery
positive and then the mains supply turned on. The indicator LED should now
be visible on the lamp head’s front bezel, showing the battery is connected
and being charged.
The One-LED Solo SurfaceTM will stay in commissioning mode for a minimum
of 48 hours + the Duration Test period. The rst 24 hours is to fully charge
the battery before its Duration Test and second 24 hours to recharge the
battery for normal use.
If it is anticipated that the un-switched supply may be interrupted
before normal use, we advise that the battery is left disconnected and
commissioning is delayed to avoid damage until the supply is stable.
If the luminaire has been stored for a number of months, it may be necessary
to repeat the initial charge/discharge process several times to re-condition
the battery and achieve full rated emergency duration.
After successful commissioning, the battery should be marked with the date
of commission.
A Solo SurfaceTM can be returned to stand alone self test at any time
by disconnecting it from the DALI network and forcing a Function Test
from the test switch or by cycling the un-switched mains supply. (See
information tables below for details).
To fully reset all test times, disconnect the mains, battery power and
DALI connections. Once power is restored, the commissioning cycle and
randomisation process will be re-initiated.
Short discharge periods each month for the Function Test will not adversely
affect One-LUX batteries and should be considered as a maintenance
exercise for the battery. Regular full discharge cycles will however adversely
affect the design life of the battery, so excessive testing should be avoided
wherever possible.
A full summary of automatic test timings can be seen in the tables below.
The status of the Solo SurfaceTM can be determined at any time from the
indicator LED. Details of the indicator LED status conditions and integral
test switch functionality can be found on page 6.
