Emergency lights are designed to operate for a minimum 90-minutes after AC power to a building is lost. The 90-minute specification is specified in the NFPA Life Safety Code. The Life Safety Code was and still is used by UL (Underwriter Laboratories) to create the UL 924 Standard for Emergency Lighting and Exit Sign Fixtures. The UL 924 Listing on all of hour emergency lights insures a minimum 90-minute run time.
But, sometimes 90-minutes is not enough. There are many types of commercial and industrial applications where an extended run time is desired. This can be the case for large processing and manufacturing facilities, areas where rolling blackouts can occur, and areas where when power is lost, it typically takes more than 90-minutes for it to be restored. For these instances, we design, build, and recommend our High Capcity Emergency Light. Choose an emergency light with a 3,4,6 and 8-hour extended run time, tripling the minimum requirement set by the NFPAs Life Safety Code.
- Provides 3, 4, 6 or 8 hours of emergency illumination
- Constructed from durable 20-gauge steel
- Powerful 9-watt Halogen lamps are standard
- Sealed lead acid battery comes with test button
- UL 924 Listed, meets NFPA Life Safety Code, compliant throughout North America
Emergency lights with a 3-hour run time are designed for commercial applications where more than 90-minutes of emergency illumination will be required. This is common in a variety of applications.
The extended runtime emergency light is manufactured from heavy-duty 20-gauge steel that is finished with a baked enamel white powder coat. The lamp heads are mounted on top of the unit and can easily be adjusted.
Utilizes 120/277v AC electricity to operate and charge the battery. Comes standard with solid state charging circuitry, low voltage disconnect, AC lockout, and brownout protection. Available in custom voltages upon request.
9-watt lamp heads come standard on the steel 3-hour emergency light and the 3-hour oudoor emergency light. 9-watt lamp heads are almost double the illumination power of 5.4-watt lamps that typically come on most emergency lighting fixtures.
Higher and more powerful lamp heads are also available; please call us to discuss other options and a price quote. Higher wattage lamp heads are popular for industrial emergency light applications. Photometric data is available for all lamp head choices.
Emergency lights with a extended run time lights come standard with a 6 or 12 volt sealed lead acid emergency light battery.
The recharge time for the battery of our high capacity emergency light is 24 hours and the max working temperature for the battery is 122° F. The sealed lead acid battery has an average lifespan of 3 to 5 years. Make sure to test your emergency light batteries on a monthly and yearly basis to comply with OSHA testing requirements.
To purchase a model with one or more of the options below (that are not offered above) please contact us via email or call us at 800-480-0707 for price and availability.
Self-Testing - The unit can come with self-diagnostic testing that eliminates monthly and yearly testing of the battery backup system and alerts the user to any problems regarding operational functionality of the unit.
Time-Delay - This option is ideal for installations that are utilizing fluorescent and HID lamps for general lighting purposes. The time delay feature keeps the emergency lights ililluminated for a preset period (usually 15 minutes) after power is restored since fluorescent and HID lighting can take 10-15 minutes to reach full brightness, even after a short power failure.
Nickel Cadmium Battery - The unit can come with a nickel cadmium battery. A step above the standard sealed lead acid batter, Ni-Cad batteries have a 5-7 year lifespan, are easier to replace, and decrease shipping weight. Nickel cadmium emergency light batteries are only available on the steel and wet location battery backup emergency light models.
Back mount to normally inflammable surfaces. Conduit knockouts are located on the back and sides of the fixture.
