Emergency Ballasts

APPLICATION FEB 500

• The FEB500 fluorescent emergency ballast works in conjunction with the AC ballast to convert new or existing fluorescent fixtures into emergency lighting.  The emergency ballast consists of a high-temperature nickel cadmium battery, charger and electronic circuitry in one compact white case.  The FEB500 can be used with one 17 W through 40 W (2' - 4') 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.  If used in an emergency-only fixture, no AC ballast is necessary.  This ballast is not suitable for use in air handling heated air outlet fixtures, and wet or hazardous location fixtures.

OPERATION

• When AC power fails, the FEB500 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.

INSTALLATION

• The FEB500 does not affect normal fixture operation and may be used with either a switched or unswitched fixture.  If a switched fixture is used, an unswitched hot lead must be connected to the emergency ballast.  The emergency ballast must be fed from the same branch circuit as the AC ballast.  The FEB500 may be installed inside, on top of, or remote from the fixture.  The emergency ballast may be remote-installed up to half the distance the AC ballast manufacturer recommends remoting the AC ballast from the lamp, or up to 50 feet, whichever is less.  Installation is not recommended with fixtures where the ambient temperature may fall below 0°C for extended periods.

UL AND CODE COMPLIANCE

• The Ballast have been tested by Underwriters Laboratories 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.
