What UL 924?
UL 924 is UL’s Standard for Safety of Emergency Lighting and Power Equipment. UL tests and certifies exit signs, emergency lights, and combo emergency exit signs to meet functionality, reliability, and visibility standards.
What is a central lighting inverter?
Central Inverter Basics Lighting Inverters ensure uninterrupted power to devices in times of power outages. They do this using a battery system that converts DC to AC voltage via electronic circuitry. During utility power, batteries are charged and during outages, batteries back up devices.
Can a UPS be used for emergency lighting?
Reliable backup power ensures you have a safe environment in the event of an emergency. Not only can a UPS keep essential operations up until generators turn on or full power is restored, but it can also power your emergency lighting systems for safe evacuation or navigation.
What is a directly controlled luminaire?
A Directly Controlled Luminaire is an emergency luminaire that has a control input for an integral dimming or switching function that drives the luminaire to full illumination upon loss of normal power.
What is the difference between UPS and inverter?
The main function of the UPS is to store the electric supply whereas the inverter converts the AC power into DC power. During the power outages, the UPS immediately switch over from the main supply to the battery whereas the inverter has a time delay.
How does a central inverter work?
Central inverters convert the DC power collected from an array of solar modules into AC for connection to the grid. They are typically floor or ground mounted, as opposed to string inverters, which are typically installed on a wall or other vertical structure.

Can exit signs be dimmed?
Basically, in theatres and similar locations, all the lights can be dimmed during the performance, even the emergency lighting and exit signs.
Do you need an inverter for emergency lighting systems?
They also help facilities meet NFPA’s life safety requirements and UL’s 924 code, two standards your systems must meet. You can buy emergency lighting units with backup batteries, which can meet the requirements without an inverter.
What is the battery life of a lighting inverter?
Controlled Power Company manufactures single phase lighting inverters rated at 550W – 18kW, and three phase models at 10kW – 55kW. The standard battery runtime is 90 minutes at full load, with alternative runtimes available. Seismic-rated models are available! SELECT AN EMERGENCY LIGHTING INVERTER
Do Your inverters meet NFPA standards?
With NFPA standards reflecting automatic testing of life safety systems and computer-based reporting of test results, our inverters are being used more now than ever before! That’s because we offer models that meet (and can exceed) the automatic testing defined in NFPA 101 – 7. 9. 3. 1. 3.
