shall be read in conjunction with other parts of the ContractDocumentation.

B. The work shall include the interim, detailed and final design, manufacture,supply, installation, supervision of own work and test & commissioning of

the General Lighting including all necessary accessories and coordination

work as shown on the drawings and specified in relevant specifications and

as herein specified, and to the satisfaction of the Engineer.

C. The General Lighting consists of the following, but is not limited to:

1. Illumination level requirement.2. Emergency lighting.3. Switchboards for emergency lighting.4. Central battery system - mains power supply.5. Self contained emergency battery packs.

D. The Contractor shall coordinate with all relevant specialist sub-contractorsto ensure that the location of Luminaires shall not interfere with the

operation and functionality of any other equipment such as, but not

restricted to, Moving/Intelligent displays and/or illuminated signage of any

type with particular reference to Reflection and Glare.

E. The Contractor shall ensure that the general distribution of light shall beuniform avoiding "Hot-Spots" creating a general relaxed atmosphere.

F. The design shall incorporate necessary allowances for the effect ofcondensation and any subsequential damage to equipment, finishes and

by an integral charger such that the system supplies not less than 85 % of

its rated voltage after a period of 12 hours.

G. Suitable Luminaires selected from the general lighting scheme shall bepowered from the inverters and wired independently of other systems,

using fire-resistant cabling.

H. Central controlled system with central battery system shall be used exceptwhere specified elsewhere. The centralized system shall fulfil the

requirements in accordance with BS EN 50171 and shall as a minimum

perform to the following requirements:

1. Individual light monitoring.

2. Light output - 100 %.

3. Automatic function test.

4. Automatic duration test.

5. Data access/control at central location.

6. Interface to Airport SCADA.

7. 10 years battery life time by 20 C.

8. 2 years electronic log book facility.

9. Maintenance free sealed lead acid batteries.

10. The design shall allow 20 % spare capacity for future expansion. Inaddition, a derating factor of 0.8 shall be applied to negate the effect

of battery ageing so that batteries will supply the load for the full

discharge duration throughout their useful life.

12. AC/AC static inverters, which convert DC power from a built-instandby battery to 240V AC 50Hz single-phase power shall be

provided.

13. Luminaires designated for emergency operation, shall operate to theprinciples shown on drawings.

14. The proposed emergency lighting levels shall be in accordance withBS EN 1838, local Regulations, NFPA 101 and the Fire Safety

Strategy Report. The lighting level shall be archived at any time

during the system life including de-rating due to dirt, components

ageing and the reduction in battery voltage as the battery discharges,

however the below table shall be followed as a minimum:

2.3.2 Switchboards for emergency lighting

A. The design, material, construction and performance of switchboards foremergency lighting shall comply with the latest international standards.

B. Switchboards shall be shipped to and stored securely taking into accountconditions found at site. When the switchboard final location is ready to

receive the said switchboard, they shall be installed into position. Once inposition the switchboards shall be finally assembled, including all

components and connections being torque tested in accordance with the

manufacturer's recommendations to ensure there are no loose connections.

C. All indoor switchboards shall be IP 43 ingress protection according to BSEN 60529.

D. Switchboards shall be designed for the following ambient conditions:

1. Outdoor maximum ambient temperature 50 C.

2. Indoor maximum ambient temperature 41 C.

E. Access to the switchboard interior and the protective devices shall be bymeans of a hinged door fixed shut by means of a moulded lever type latch

which shall be able to be locked with the means of a proprietary locking

system.

F. With the door in the open position, it shall not be possible to touch or gainaccess to live parts without the use of a tool. The hinged door shall be

easily removable when in the open position to aid installation and

maintenance.
