Philips Bodine B33 - Parallel Emergency Ballast - 90 Min. - Operates (2) or (3) 32W 4Ft T8 Fluoresent Lamps - 120/277V

APPLICATION

The B33 emergency ballast works in conjunction with an INSTANT START, PARALLEL AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency balast consists of a nickel-cadmium battery, charger and electronic circuitry. The B33 can be used with two or three 32 W (4’) T8 fluorescent lamps without integral starters. It is compatible ONLY with instant start, parallel two-, three- or four-lamp electronic or standard AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. The B33 is suitable for indoor and damp locations. It is not suitable for air handling heated air outlets or wet or hazardous locations. For information about specific lamp and ballast compatibility, please call the factory. Recommended applications include: hospital surgical suites, areas along the path of egress with high ceiling heights and health care, educational, commercial and institutional facilities needing higher levels of emergency illumination.

OPERATION

When AC power fails, the B33 immediately switches to the emergency mode, operating either two or three lamps for a minimum of 90 minutes. When AC power is restored, the B33 automatically returns to the charging mode.

INSTALLATION

The B33 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 B33 may be installed on top of or remote from the fixture. 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 +5°C. A charging indicator light and single-pole test switch are provided. Upon request, a single-pole test switch/ monitor plate is provided for remote installation of the test switch and charging indicator. (fits single-gang box)

EMERGENCY ILLUMINATION

The B33 has been optimized for three-lamp operation. The B33 produces 3250 to 3400 lumens initial emergency light output with three 32 W (4’) T8 lamps. Total light output is evenly divided among the lamps for better distribution of emergency illumination.
