B70A Bodine Ballast

APPLICATION
The B70A 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 red case. The B70A can be used with most 17 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) compacts. 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. The B70A is not suitable for use in air handling heated air outlet fixtures, and wet, damp, or hazardous location fixtures. For information about specific lamps and ballast compatibility, please call the factory.
 
OPERATION
When AC power fails, the B70A immediately switches to the emergency mode, keeping one lamp illuminated at a reduced lumen output for a minimum of 90 minutes. Two hour duration may be selected with one 17 W-32 W T8, or one 20 W-40 W T10 or T12 fluorescent lamp. When AC power is restored, the B70A automatically returns to the charging mode. 
 
INSTALLATION
The B70A 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 B70A 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 B70A 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. 
 
BATTERY
Since high temperatures exist in fluorescent fixtures, the B70A uses a specially constructed, high-temperature nickel cadmium battery. This battery requires no maintenance, and has a life expectancy of 7 to 10 years. 
 
EMERGENCY ILLUMINATION
The B70A produces 600 to 700 lumens initial emergency light output. During emergency illumination, one lamp is illuminated, even if installed with a multi-lamp AC ballast. Emergency lumen output will be less with a compact fluorescent lamp. 
 
SPECIFICATION
Emergency lighting shall be provided by using a standard fluorescent fixture equipped with a Bodine B70A 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" red 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 17 W-215 W (2'-8') T8, T10, or T12 fluorescent lamp or (4-pin) compact fluorescent lamp at reduced illumination in the emergency mode for a minimum of 90 minutes; or one 17 W-32 W T8 or one 17 W-40 W T10 or T12 fluorescent lamp at reduced illumination in the emergency mode for a minimum of 120 minutes. The B70A shall produce 600 to 700 lumens initial emergency light output, have 3.5 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 for installation inside, on top of, or remote from the fixture, warranted for a full three years from date of purchase, and made in the U.S.A. 
 
WARRANTY
Model B70A is warranted for three (3) full years from date of purchase. This warranty covers only properly installed Bodine emergency ballasts used under normal conditions. For the warranty period Bodine 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.
