An emergency lighting system is designed to create personal safety and allow the safe evacuation of the building. An emergency lighting system must work faultlessly in all situations which is why high demands are made on reliability. The system is a safety element and must be well designed and planned. The design of emergency lighting systems are specifi ed in the standards BS 5266 Parts 1 & 7 and EN 1838 Demands are made in the standards for different environments and application areas. Examples of different environments where demands vary are: escape routes, anti-panic lighting and lighting of high risk areas. The emergency lighting system usually consists of a combination of safety signs and general luminaires equipped with an emergency lighting function. An emergency lighting system can be either centralised or decentralised, i.e. with a central power supply or with an integratedemergency lighting solution direct in the luminaire.

Central battery system based emergency lighting is ideal for medium to large installations. For projects where central control and testing is desirable, a central battery system is a viable and cost effective alternative to self-contained emergency lighting products. The main advantages of central battery systems over self-contained systems are:
• Testing and maintenance is much easier to carry out
• Battery replacement is much quicker and less disruptive
• Battery life is generally 10 years or more
• Luminaires can be centrally controlled
• High light levels can easily be achieved
The system is based around an addressable, emergency lighting control panel with battery back-up and features addressable, self contained luminaires and signage connected via traditional extra low-voltage cabling. Low maintenance with a considerable reduction in lamp changes compared to traditional lighting, makes this system a cost effective solution for the life cycle of any building.
