All high occupancy and commercial buildings are required to have emergency lighting systems installed as standard these days. They are needed in the event of the normal lighting systems failing as in the case of a fire, where the occupants may need to leave the building quickly and, for that reason, they have been called egress lights. If there were no lighting in a building it would be a very hazardous environment; particularly for children, old, disabled or sick people as they can be easily injured in the rush and panic to escape.
In the past, emergency lighting was a bulky and expensive installation, either powered by a generator or lead acid batteries, sometimes in large banks to provide an immediate backup if the main lights fail for any reason. These systems are still in use today but are often supplemented by battery backup in case the generator fails. KDE are industry leaders in the field and our team of specialist advisors is here to help.
These days it is normal for emergency lighting systems to run on 6 or 12 volts and the lights will be powered by batteries on a charging circuit with highly efficient incandescent or newer LED arrays and reflectors, (often included in the design of new buildings) Sometimes a transformer is integrated into the light housing to step down the voltage from mains to 6v or 12 dc. Either way, they are designed to activate automatically by circuit breaker in the event of a power outage or lighting failure. Here at KDE we have a wide range of emergency lighting units and the technical experience and knowledge to help you to make the right choice for your property or work place.
These systems are designed to help people to see well enough to make their way to an emergency exit when the main lights are down. Sometimes the emergency lights are actually combined into the design of the main lights, some are on all the time even when the main lights are on, on permanent charge with a battery life of at least 90 minutes, which is considered by the manufacturers a long enough time to make an exit and for the fault to be repaired, if possible. It is normal for emergency lights to be positioned so they can be aimed at emergency exit points and, in some cases, the designers have also positioned them low enough to not be obscured by smoke as it often circulates around the ceilings due to the heat in the case of a fire in the building.
