This luminaire in which the emergency and maintained lamp source will be lit at all times and operates as normal with all the other lights in the area from the mains supply, however when the power fails the maintained emergency fitting will continue to operate, but at a lower level using the back up batteries.
Luminaires can be switched on and off, but will still illuminate at a lower level on the loss of mains power.
Non maintained Emergency Lighting is a luminaire made solely for emergency use, it is designed to come on in the event of a mains failure, making sure all emergency exit routes are clearly illuminated, but will not be active as your normal lighting.
A luminaire containing two or more lamps at least one of which is energised from the emergency supply and the remainder from the other supply. (If the Emergency Lamp is only illuminated in a mains failure condition this is regarded by the fire authority as non maintained.
Central battery systems are normally used for larger projects. An AC/AC static inverter system can be connected directly to the designed mains luminaires without having to make any modifications. They operate both at full output in mains healthy and mains failure mode conditions. Battery life is usually 10 years. When replacement is necessary this is quick to replace and a simple operation that avoids the disruption caused by having to access and dismantle numerous luminaires in areas occupied. Central systems are simple to test easy to maintain and provide a completely unobtrusive emergency lighting system with long-term cost advantages.
