Understanding\nthe UL 924 standards<\/strong><\/p>\n\n\n\n

While shopping for emergency lighting\nfixtures or exit signs, you have probably seen that many products come with a\nlabel or description that says \u201cUL 924 listed\u201d. In this post, we\u2019re going to\nbriefly discuss what UL 924 means, what the UL 924 requirements are, and why\nEmergency Exit Signs and Lights with this certification are encouraged.  <\/p>\n\n\n\n

What does UL 924 mean? <\/strong><\/p>\n\n\n\n

The Underwriters Laboratory (UL) is an\nindependent testing organization established in 1894 that provides testing and safety\ncertifications for all types of products, components and materials. UL 924 is the\nUnderwriters Laboratory \u201cStandard for Safety of Emergency Lighting and Power\nEquipment.\u201d<\/p>\n\n\n\n

When you see \u201cUL 924 Listed\u201d or \u201cUL Listed\u201d, this means that a product and all of its components have been tested and reviewed by the Underwriters Laboratory, and has been certified to meet or exceed specific safety, electrical and fire hazard codes required for all commercial properties in the United States.* <\/p>\n\n\n\n\n\n\n\n

What are the UL 924 requirements?<\/strong><\/p>\n\n\n\n

For emergency lighting<\/strong><\/a> to meet UL 924 standards, the light fixture must provide illumination for at least 90 minutes in the event of power failure due to an emergency or other other power-power failure situation. This is the time estimated to be long enough for the occupants of a building to safely evacuate in the event of a disaster, especially without sustaining any injury that could potentially make evacuation more challenging. In order for the emergency light to remain lit for at least 90 minutes, it must be connected to an internally hardwired backup battery. <\/p>\n\n\n\n

In addition to that, it has been\ndetermined that the emergency lighting fixture should provide immediate and\nsufficient illumination in the event that there is a power outage. <\/p>\n\n\n\n

Emergency exit signs<\/strong><\/a> also come under a similar set of regulations when it comes to UL 924 compliance standards. The hardwired battery backup systems inside exit signs, which provide illumination during power outages, also must provide at least 90 minutes emergency operation. Exit signs can also be directly connected to the building\u2019s backup power supply. Underwriters Laboratory allows for the color of an emergency exit sign’s or combo units<\/strong><\/a>‘ letters to be either green or red (some jurisdictions mandate one or the other), and the letters will need to be at least six inches tall with a letter thickness that measures \u00be of an inch. It should also have 3\/8 of an inch in space between its letters.  <\/p>\n\n\n\n

In addition to all of this, the signs need to have at least 0.06 foot lamberts in luminance, as well as a 100 foot viewing distance. While there are some anomalies to the viewing distance rule, this will only be allowed if the emergency exit sign is marked with what the actual viewing distance is. <\/p>\n\n\n\n

Why should you purchase UL 924 listed\nfixtures? <\/strong><\/p>\n\n\n\n

In short, peace of mind. The UL 924 label\nmeans that your life safety product is code compliant nationwide*, and has been\nthoroughly tested for reliability and performance. <\/p>\n\n\n\n
