UL 924 STANDARDS

UL 924

Lighting Inverter Supply only works with UL 924 standard, tested, and certified systems, providing you with the industry’s highest capacity and efficiency systems. 90-minute lighting inverter systems provide industry-wide solutions for the current UL 924 standard. Article 700 or 701 of the National Electrical Code, NFPA 70, the Life Safety Code, NFPA 101, the Fire Code, NFPA 1, the International Building Code, IBC, and the International Fire Code, IFC.


UL 924 Standard REQUIREMENTS

Inverters help provide uninterrupted power to lighting systems in the event of an outage. This is important for facilities because emergency lighting must remain lit for at least 90 minutes when the power goes out. They also help facilities meet NFPA’s life safety requirements and UL’s 924 code, two standards your systems must meet.

HOW THEY HELP

You can buy emergency lighting units with backup batteries, which can meet the requirements without an inverter. Depending on the size and makeup of your facility, you may need more power to meet demand. Usually this comes from a backup generator or battery sets connected via diodes. The inverter helps provide power by converting electricity to a useable format. Facilities use alternating current, while the backup (emergency) power generally comes from a direct current. The inverter will convert the DC power to an alternating current, allowing your facility to continue functioning as it had before the outage.

UL 924 and NFPA 101: GETTING THE RIGHT INVERTER

The costs of inverters can vary from hundreds to thousands of dollars. You may easily be able to get by with a low cost solution, but before you decide, it’s good to get a second opinion before making a big investment. Whether you want to go at the shopping process alone or consult a guide, you should ensure each inverter you look has two very important listings: NFPA 101 and UL 924. To meet inspection and avoid liability, your backup power system will need to at a minimum pass these codes.

Members of our team are available to assist in the system selection process. You may provide a specification to us to review with you. You may need a walk through with an Electrical contact either provided by us or your own. We will assist every step of the way. Sizing review, voltage selection, Battery Runtime options are all important variables in the selection process. Proper documentation of System manuals and technical information are an integral part of the process so that the installation technician or contractor can properly plan and estimate the project.
