In the midst of every day "normal" life, when the sun is shining and everybody is going on about every day business, it's easy to take for granted those little things we routinely walk past. But emergency exit lights, like alarms, are something you never want to dismiss.
Emergency exit lights include the EXIT sign itself, located at the doorway, and lighting along the egress route to help people see in order to get out in the event that the electricity fails.
But if the electricity fails, how will the emergency lights work? A transfer switch senses when the electricity goes off and an inverter changes the electrical current from DC (Direct Current) to AC (Alternating Current). Modern systems, according to Laura Reynolds at eHow, are hardwired to an uninterruptible power supply (UPS). Through the UPS, the battery is charging under normal circumstances; when the electricity fails, the battery supplies energy to the exit lighting system.
Once installed, your emergency exit lighting needs routine inspections. Owners should perform a basic check of their emergency lighting every 30 days. A trained technician may come at longer intervals, such as every six months to perform a more in-depth evaluation of the system. Technicians from Lighting Services Inc. will check your batteries, chargers and lamps; replace anything needed as agreed upon with the owner; and provide written documentation of the inspection findings and resulting maintenance.
While the electricity is on and everybody's going about their every day business, it's a good time to contact us for more information about what we can do to insure that your emergency lighting system will function when you need it most.
