Emergency lighting batteries are very reliable and provide a large degree of flexibility in responding to all kinds of emergencies

Many of these emergency lighting batteries are long-life devices that provide years of dependable service, even in extreme weather conditions. However, in the event of a serious power outage, it may be necessary to improvise. One good way to do this is to attach a second emergency lighting battery to the primary power supply of the facility. This extra battery will provide sufficient illumination for at least one more floor of the structure. If all the exit signs are still in place and powered up, one can proceed to the main access point and begin guiding people out. Some systems allow only certain areas of the building to be illuminated, while others include an area-by-area layout that provides for mass evacuations.


The most convenient option is, of course, to use a self-contained system that includes every building in the facility as well as an extra backup, main battery. These systems are very reliable and provide a large degree of flexibility in responding to all kinds of emergencies. However, many commercial structures are being built with central heating and air conditioning in mind, and central batteries are often insufficient in severe weather. A self-contained emergency lighting battery system will provide sufficient illumination for all interior floors in a building when electricity is out and a secondary source of power is needed.
