Exit and emergency lighting is required by the United States in all commercial, industrial and architectural environments. This includes schools, offices, hospitals, shopping centers and prisons. Paths of egress must be illuminated by emergency signs and pathway lights. Emergency lights can be illuminated by using LED or incandescent technology. Exit and emergency lighting can be a key factor contributing to the overall fire safety of a building. Exit signs must be illuminated at all times, even when the building is not occupied.
Lighting inverters provide power to designated emergency lighting fixtures. In a power loss situation, they supply power from the onboard battery supply, and works in conjunction with incandescent, LED, and fluorescent lamp and fixture types and will automatically run switched, normally-on, or normally-off designated emergency fixtures.
When selecting an emergency lighting inverter, it is mandatory that the system is UL 924 listed. UL 924 ensures that the battery backup system has passed several critical discharge and recharge tests which are required for life safety. All of our standard 90 minute inverters are listed as UL 924 “Emergency Lighting Equipment”, and are NFPA 101 compliant. Each inverter model is easy to install, and many boast of an industry-leading small cabinet footprint.
With NFPA standards now reflecting automatic testing of life safety systems and computer-based reporting of test results, these inverters are being used more now than ever before. That’s because we meet (and can exceed) the automatic testing defined in NFPA 101 — 18.104.22.168.3.
Lighting designs for new construction and retrofit projects are now including LED fixtures … and of course, some of these LED fixtures will be designated for emergency egress lighting. To stay on par with the LED lighting trend, we offer inverters with a high peak overload capability to accommodate the inrush current from LED fixtures / drivers while the inverter is fed from the AC power source, or even while in battery mode.
