Emergency power system - Wikipedia, the free encyclopedia (969 words) |
 | Emergency power systems are a type of system, which may include lighting, generators and other apparatus, to provide backup resources in a crisis or when regular systems fail. |
| Emergency power systems were used as early as World War II on naval ships. |
| Unlike emergency lights, emergency lighting is not a type of light fixture, it is a pattern of the building's normal lights that provides a path of lights to allow for safe exit in case of an emergency or light up service areas such as mechanical rooms and electric rooms. |

| Emergency lighting is also essential if there is a fire in the building as this could cut the electrical supply. |
| Self-contained emergency light fittings contain a battery charger, a rechargeable battery and a light source, which is usually an 8-watt fluorescent tube. |
| Emergency lighting units are available in two kinds: "non-maintained" (which come on only in a power failure) or "maintained" (which can be on all the time). |
