230 VAC - Emergency Backup Drivers

An emergency backup driver provides essential backup power to lighting systems during power outages. These drivers continuously monitor the power line for any disruptions, and upon detecting an outage, they automatically switch the power source from the main supply to an internal battery. The National Fire Protection Association (NFPA) mandates the use of emergency drivers in various commercial and residential structures to meet compliance codes and ensure safety and visibility in emergency situations. 

There are three different types of emergency backup drivers. High-voltage LED emergency drivers are wired between the main power line and the light fixture inputs. These often require 0-10V dimmable LED fixtures to dim the lighting and conserve battery energy. Low-voltage LED emergency drivers replace the existing driver during power outages and directly connect to the LEDs. Lastly, an all-in-one emergency driver features a compact LED array that illuminates instead of the light fixtures during a power outage. These kits are typically installed in troffer and linear strip fixtures.

UL 924 mandates that emergency backup drivers have manual test switches. Wall-mounted, ceiling-mounted, integrated, and remote-controlled test buttons are available depending on the fixture and desired mounting location. The National Fire Protection Association (NFPA) Life Safety Code 101 also mandates that backup power systems must provide power for at least 90 minutes. Initial backup power illumination must average 1 ft-candle but reach no less than 0.1 ft-candle at any distance along the egress. Visual tests are also required at least every 30 days for 30 seconds. A status indicator on the driver must clearly show any testing failures, ensuring that emergency drivers are always ready to operate when needed.
