The S66F-UNV Universal Input fluorescent emergency ballast works in conjunction with an AC ballast to convert fluorescent fixtures into emergency lighting. The emergency ballast handles a wide range of input voltages and frequencies, and consists of a high-temperature nickel-cadmium battery, charger, and electronic circuitry in one compact red case. The S66F-UNV can be used with most 13 W through 215 W (2' -8') T8, T10, or T12 fluorescent lamps without integral starters, including U-shaped, HO, VHO, circline, energy saving, and (4-pin) twin, quad, triple twin-tube, and long compacts (see Table 1). It is also compatible with most 120 through 277 VAC (50 or 60 Hz) 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. The emergency ballast is suitable for use in indoor fixtures EXCEPT air handling heated air outlets, and wet, damp or hazardous location fixtures. For information about specific lamp and ballast compatibility, please call Side-Lite.

Recommended applications include: International line voltages from 120 through 277 VAC (50 or 60 Hz); drilling rigs where generators are the primary source of power; and other applications requiring higher tolerance of line voltage variation or circuits containing harmonic distortion.

When AC power fails, the S66F-UNV immediately switches to the emergency mode, keeping either one or two lamps illuminated at a reduced lumen output for a minimum of 90 minutes. Two hour duration may be selected with one 32 W T8 fluorescent lamp. When AC power is restored, the S66F-UNV automatically returns to the charging mode.

The S66F-UNV 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 emergency ballast may be remotely 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.

The S66F-UNV has been tested by Underwriters Laboratories in accordance with the standards set forth in UL924 – “Emergency Lighting and Power Equipment,” and is UL Listed for factory installation or field retrofit. Emergency illumination time exceeds the National Electrical Code (NEC), Life Safety Code (NFPA–LSC) and UL 90-minute requirements.

Since high temperatures exist in fluorescent fixtures, the S66F uses a specially constructed, high-temperature nickel cadmium battery. This battery requires no maintenance, and has a life expectancy of 7 to 10 years.

Depending on the number (1 or 2), wattage, and type of lamps selected, the S66F-UNV produces 300 to 700 lumens initial emergency light output (see Table 2). If two-lamp operation is selected, light output is evenly divided between the lamps for better distribution of emergency illumination.

Emergency lighting shall be provided by using a standard fluorescent fixture equipped with a Side-Lite S66F-UNV Universal Input fluorescent emergency ballast. This emergency ballast shall consist of a high-temperature, maintenance-free nickel-cadmium battery, charger and electronic circuitry contained in one 9 3/8" x 2 3/8" x 1 1/2" metal case. A solid-state charging indicator light to monitor the charger and battery, a double-pole test switch, and installation hardware shall be provided. The emergency ballast shall be capable of operating [one or two]_________ fluorescent lamp(s) at_______lumens (see Table 2) initial light output in the emergency mode for a minimum of 90 minutes; or one 32 W T8 fluorescent lamp at reduced illumination in the emergency mode for a minimum of 120 minutes. The S66F-UNV shall have 5.0 Watts of input power, a 14.4 Watt-hour battery capacity, and comply with emergency standards set forth by the current NEC. The emergency ballast shall be UL listed, warranted for a full three years from date of purchase, and made in the U.S.A.

Model S66F-UNV is warranted for three (3) full years from date of purchase. This warranty covers only properly installed Side-Lite emergency ballasts used under normal conditions. For the warranty period Side-Lite will, at its option, repair or replace without charge a defective emergency ballast, provided it is returned to the factory transportation prepaid, and our inspection determines it to be defective under terms of the warranty. Repair or replacement, as stated above, shall constitute the purchaser’s exclusive warranty, which does not extend to transportation, installation, labor or any other charges; nor does it apply to any equipment of another manufacturer used in conjunction with the emergency ballast.
