If sufficient open area emergency lighting is in the vicinity of a fire exit, non-illuminated fire exit signs can be sufficient in locations of minor importance. Photo-luminescent fire exit signs would be preferable in this case, although it has to be ensured that sufficient light is reaching the photo-luminescent sign to ensure it is ‘charged’ at all times. Considerations From a practical point of view, a normal caretaker would be able to use a test key to remove power from emergency lights and ensure that the emergency lights stay on the required period. When it comes to repair of failing emergency lights it would most likely that an electrician would be needed unless the caretaker has sufficient qualifications to replace batteries and lamps. It's swings and roundabouts in the building as some areas the key switch shuts off the power to the lights (per room, location) and illuminates the EL. The new refurbished areas the key switch does not cut power to the lights, and with some EL units being part of the main lights this poses a problem to actually see if they are working or not. Yes they have green LEDs in them but you have to look closely to see if they are actually coming on as required. Simple system would be you switch the main lights on as normal, then operate the test key switch which simulates a power cut - so you can visually see the EL works.

Five or six storey house converted to self-contained flats require conventional lighting and emergency escape lighting. Importantly, common escape routes should be well lit.As I understand it the EL light units that (should) have LEDs on them, the LEDs are illuminated when in normal 'charging' mode but go out when in EL mode? A non-maintained emergency light will only light up in the event of a mains power failure and will also stay lit for the minimum emergency duration required. Non-maintained emergency lights are likely to be found in offices, shops andfactories. They would need to be conversant with BS 5266-1- 2011 Emergency lighting-Part 1: Code of practice for emergency lighting of premises.

Single occupancy houses and houses of multiple occupancy up to two storeys high only need conventional lighting, whereas three and four storeys may require emergency escape lighting if the escape route is complex and there is no effective borrowed light. First floor has a conference room, dining area, servery and kitchen with adjourning conveniences, 11 rooms (classroom or meeting/training rooms), 5 office rooms and 3 sets of conveniences. British Standard BS 5266-1: 2011 provides clear guidelines about the design and installation of emergency lighting. It should be remembered that the British Standards specify the best practice for standard situations, however, a higher standard may be required for a particular installation.Maintained emergency lights stay on constantly at all times and stay lit for the minimum emergency duration (usually 3 hours) after a mains failure. Maintained emergency escape lights are used in places of assembly like theatres, cinemas, entertainment halls but also shopping centres and similar venues. They allow the public to familiarise themselves with emergency routes and have the advantage that any failure of the emergency lighting bulbs can be spotted immediately. An emergency lighting system should be installed by an electrician who specialises in emergency lighting. The occupier/owner of the premises should appoint a competent person to supervise the testing of the system. This person shall be given sufficient authority to ensure the carrying out of any work necessary to maintain the system in correct operation. Competent can be defined as someone who has sufficient training and experience or knowledge and other qualities that allow them to maintain the system properly. The level of competence required will depend on the complexity of the situation and the particular help that is required.
