The B94C-CAN fluorescent emergency ballast works in conjunction with an AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency ballast consists of a hightemperature nickel-cadmium battery, charger and electronic circuitry in one compact red case. TheB94C-CAN can be used with most 6 W through 42 W fluorescent lamps without integral starters, including 4-pin twin-, quad-, and triple-twin-tube compacts see Table 1 . It is also compatible with most one-, two-, three- and four-lamp electronic, standard, energy-saving and dimming AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. The B94C-CAN is suitable for indoor locations. It is not suitable for air handling heated air outlets or wet, damp or hazardous locations. The B94C-CAN is not recommended for use with low mercury compact fluorescent lamps.
