PRODUCT OVERVIEW
APPLICATION
The BAL32 low-profile 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 case. The BAL32 can be used with one (1) 17W-40W (2’ - 4‘) T8, T10 or T12 fluorescent lamp without integral starters, 8W-28W T5 fluorescent lamp and 17W-40W (4-pin) long compact lamp. It is also compatible with most electronic 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. For information about specific lamp and ballast compatibility, please consult the factory.
OPERATION
When AC power fails, the BAL32 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 BAL32 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 BAL32 may be installed inside or on top of the fixture. Installation is not recommended with fixtures where the ambient temperature may fall below 0ºC for extended periods.
UL AND CODE COMPLIANCE The BAL32 has been tested by Underwriters Laboratories in accordance with the standards set forth in UL 924, “Emergency and Power Equipment,” and is UL Listed for factory or field installation. Emergency illumination time exceeds the National Electric Code (NEC), Life Safety Code (NFPA-LSC) and UL 90-minute requirements
BATTERY
Since high temperatures exist in fluorescent fixtures, the BAL32 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 BAL32 produces 450-500 lumens initial emergency output. During emergency illumination, one lamp is illuninated, 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 Best BAL 32 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" white metal case. A solid-state charging indicator light to monitor the charger and battery, a single-pole test switch, and installation hardware shall be provided. The emergency ballast shall be capable of operating (1) 17 W - 40 W (2' - 4') T8, T10, or T12 fluorescent lamp without integral starters, 8W – 28W T5 fluorescent lamp and 17W – 40W (4-pin) long compact lamp at reduced illumination in the emergency mode for a minimum of 90 minutes. The BAL 32 shall produce 450 to 500 lumens initial emergency light output, have 2.5 Watts of input power, a 9.6 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 year from date of purchase, and made in the U.S.A.
WARRANTY
Model BAL32 is warranted for five (5) full years from date of purchase. This warranty covers only properly installed emergency ballasts used under normal conditions. For the warranty period, ESW 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.
