Emergency lighting code requirements vary by jurisdiction, but generally adhere to standards set by organizations like the National Fire Protection Association (NFPA) and the International Building Code (IBC). Key requirements include: 1. **Illumination Levels**: Emergency lighting must provide a minimum illumination level, typically 1 foot-candle (10.8 lux) at the floor level in exit routes. 2. **Duration**: Emergency lighting systems must operate for at least 90 minutes during a power outage. 3. **Coverage**: Emergency lighting should cover all exit routes, including corridors, stairways, ramps, and exit doors, ensuring safe egress. 4. **Automatic Activation**: Systems must automatically activate upon power failure, ensuring immediate illumination without manual intervention. 5. **Power Source**: Emergency lighting must have a reliable power source, often a battery backup or generator, to ensure functionality during outages. 6. **Testing and Maintenance**: Regular testing and maintenance are required, typically monthly and annually, to ensure system reliability. This includes a 30-second monthly test and a 90-minute annual test. 7. **Signage**: Exit signs must be illuminated and visible, with contrasting colors and lettering at least 6 inches high. 8. **Location**: Emergency lights should be strategically placed to avoid shadows and ensure even distribution of light along exit paths. 9. **Compliance with Local Codes**: Local building codes may have additional requirements or variations, so it is essential to consult local regulations. 10. **Documentation**: Proper documentation of testing, maintenance, and compliance with codes is often required for inspections. These requirements ensure that emergency lighting systems provide adequate illumination for safe evacuation during emergencies.

Emergency drivers keep LED lights on during a power outage for as long as their battery backup allows, typically ranging from 90 minutes to 3 hours. The duration depends on the capacity of the battery integrated within the emergency driver system. These systems are designed to provide sufficient illumination to safely evacuate a building or navigate critical areas during an outage. The specific time frame is often determined by building codes and safety regulations, which generally require a minimum of 90 minutes of emergency lighting.

No, you cannot use an emergency driver with any LED fixture without considering compatibility and specific requirements. Emergency drivers are designed to provide backup power to LED fixtures during power outages, but not all LED fixtures are compatible with all emergency drivers.
