Philips Bodine B94CGU - Emergency Backup Ballast - 90 Min. - Operates (1) 18-42W 4-pin CFL Lamp - Universal Voltage 120-277 Volt

APPLICATION

The B94CGU 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 high-temperature nickel-cadmium battery, charger and electronic circuitry in one compact case. The B94CGU can be used with one 18 - 42 W (4-pin) twin, quad or triple twin-tube compact. 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 B94CGU 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

OPERATION

When AC power fails, the B94CGU immediately switches to the emergency mode, operating one lamp at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the emergency ballast automatically returns to the charging mode and, using a patented circuit, delays AC ballast operation for approximately three seconds to prevent false tripping of the AC ballast end-of-lamp-life shutdown circuits.

INSTALLATION

The B94CGU 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 must be connected to the emergency ballast. The emergency ballast must be fed from the same branch circuit as the AC ballast. The B94CGU 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 10 feet, whichever is less. Installation is not recommended with fixtures where the ambient temperature may fall below 0°C. For simple visual inspection of the charging indicator light and easy operational testing, the test/ monitor plate can be installed near the fixture wall switch. It may also be installed in the ceiling near the fixture to ensure an unobtrusive installation.

EMERGENCY ILLUMINATION

Depending on the wattage and type of lamp selected, the B94CGU produces 300 to 750 lumens initial emergency light output (see Table 1). During emergency operation, one lamp is illuminated, even if installed with a multi-lamp AC ballast.
