EB7 600-700 Lumen T8 Emergency Ballast
Application
The EB7 fluorescent emergency ballast works in conjunction with the AC ballast to covert new or existing fluorescent fixtures into emergency lighting. When AC power fails, the EB7 immediately switches to the emergency mode, keeping one lamp illuminated at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the ballast automatically returns to the charging mode.
Features
The EB7 has been tested in accordance with the standards set forth in UL 924, “Emergency Lighting and Power Equipment,” and is UL Listed for factory or field installation. Emergency illumination time exceeds the National Electrical Code (NEC), Life Safety Code (NFPA-LSC) and UL 90-minute requirements. It can be used with one 17W through 110W (2’-8’) T8, T10, or T12 fluorescent lamp without integral starters, including U-shaped, HO, VHO, circline, energy saving, and (4-pin) long compact. It is also compatible with most 1, 2, 3, and 4-lamp electronic, standard, energy saving, and dimming AC ballasts.
Electrical System
The EB7 uses a specially constructed, high-temperature nickel cadmium battery. It produces 600 to 700 lumens initial emergency light output. 120/277 VAC input. Single pole test switch. 24 hr recharge time. 0ºC to 55ºC ambient temperature rating.
