NEBRASKA V3 LITHIUM STANDARD & SELF-TEST EMERGENCY BULKHEAD INSTRUCTIONS
SAFETY This is a mains voltage powered luminaire. It is designed to be installed by suitably qualified personnel
only and in accordance with the applicable building and electrical regulations. Before installation or
maintenance, the electrical supply to the product must be isolated. The luminaire requires a permanent
(unswitched) live to charge the battery.
LUMINAIRE INSTALLATION
1. Remove diffuser by unscrewing the two screws.
2. Hinge the gear tray open on the two retaining straps.
3. Screw-fix the base to the chosen mounting surface using
the two screw fixing points in the base moulding at 240mm
centres. These should be drilled to a size to suit the fixing
screws.
Note: It is the responsibility of the installer to ensure
these fixing points are sealed to ensure the IP65 rating
is maintained. The use of a silicone sealant is
recommended.
4. Select one of the available cable entry points on the base (one on either end, on one side, or through the
bottom) & drill to a suitable size to suit IP65 rated (or better) cable entry gland (not provided).
5. Install cable entry gland.
6. Depending on which variant of the product you have, determine your required function & route the
appropriate power supply cable to the terminal block & terminate as shown.
7. If applicable, tighten the cable gland to seal & secure mains cable.
8. Connect the battery pack to the PCB by connecting the female socket on the battery wires to the male plug
mounted on the PCB, ensuring the correct orientation.
9. Enter the “Installation Date” in the space provided on the battery pack label.
10. Refit the diffuser & secure using the two screws opposite to step1 above.
11. Reconnect the power supply & check the green LED charge indicator illuminates.
12. The batteries should be allowed to charge for at least 24 hours before carrying out a full discharge test to
check they are charging correctly & the maintained duration is being achieved.
13. Please ensure where applicable that the self-adhesive escape route legend (included) is oriented correctly,
fixed securely, and that the viewing distance in line with BS 5499-4:2013 and BS EN 1838: 2013 is not
compromised.
OPERATION / MAINTENANCE
14. The luminaire must be replaced when it fails to meet its full rated duration in emergency mode.
15. Ensure cleanliness of the luminaire is maintained so as not to affect performance.
16. The light source of the luminaire is non-replaceable; when the light source reaches its end of life the whole
luminaire must be replaced.
17. Do not insulation test.
****************************** IMPORTANT WARNING ****************************
The luminaire uses a Lithium Iron Phosphate (LiFEPO4) battery pack which includes a dedicated protection
circuit. The luminaire is not compatible with any other type of battery chemistry.
TESTING FOR EMERGENCY LUMINAIRES
Recommended routine test procedures in line with BS 5266-1:2016 & BS EN 50172:2004

SELF-TEST VERSIONS
This luminaire incorporates a self-test facility which is designed to test automatically, in line with the testing
procedures detailed on page 1.
Pre-commission cycle
 Once connected to the permanent live supply, the luminaire must be left to charge for an
uninterrupted period of not less than 24 hours as part of its pre-commission cycle.
 Following this initial 24-hour period, the luminaire will automatically perform a 3-hour discharge test,
during which time the Bi-colour LED indicator will be off.
 On successful completion of the discharge test, the luminaire will revert to normal charge mode and
the Bi-colour LED indicator will illuminate solid green.
Monthly Function Test
 At a point during the initial 15-30 days of operation, the luminaire will perform a 30-second Function
Test, during which time the Bi-colour LED indicator will be off.
 On successful completion of the monthly Function Test, the Bi-colour LED indicator will illuminate
solid green.
 The Function Test will be repeated at monthly intervals.
 The Function Tests are performed at randomly selected times to avoid luminaires testing
simultaneously.
Annual Discharge Test
 At the end of a 12-month period, a full 3-hour Discharge Test will be performed, during which time the
Bi-colour LED indicator will be off.
 On successful completion of the annual Discharge Test, the Bi-colour LED indicator will illuminate
green.
In the event of a power outage the luminaire will continue with its pre-commission cycle after power is restored
FAULT INDICATORS
Notes:
 The fault indicator will continue to flash until the fault is cleared.
