A vital feature of any building’s safety system is emergency lighting. It is a particular type of battery-backed lighting used as the primary light source during a power outage. It also functions when the electricity has been cut off for emergency purposes such as a fire. Emergency lighting is a necessity for any public building, office, or industrial space. It ensures that people will be guided to a safe location clearly when all other lights are out. This is different from standby lighting, which is used to maintain work during a power outage.
The two main kinds of emergency lighting are maintained and non-maintained.
Maintained lighting is wired to the mains electricity so is continuously on. This makes it clear to see at all times, so perfect for buildings where people may be unfamiliar with the surroundings. It then relies on the battery as its primary power source when the electricity is off. This battery is rechargeable and can typically last up to three hours.
Non-maintained emergency lighting only runs on battery power and is activated only during emergencies. These are ideal for offices or buildings where the occupants know the designated exit routes and fire doors. This lighting will only work for the minimum three-hour emergency time frame.
