DCB-500-LP

500 Lumens Low Profile Emergency Ballast

DCB-500-LP Description

APPLICATION The DCB-500-LP 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 DCB-500-LP can be used with one (1) 14W-32W (2’ - 4’) T5 or T8 fluorescent lamps without integral starters. 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. This ballast has additional features, such as time-delay enhancement and open circuit isolation that enables the emergency battery pack to function smoothly with ;End-of-Lamp-Life’ circuitry in newer AC ballasts. This would provide an additional level of unit production from over-voltage caused by an absence of lighting load.

OPERATION When AC power fails, the DCB-500-LP 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 DCB-500-LP 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 DCB-500-LP may be installed inside or on top of the fixture. Installation is not recommended with fixtures where the ambient temperature may fall below 0°C for extended periods.

UL AND CODE COMPLIANCE The DCB-500-LP 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 DCB-500-LP 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 DCB-500-LP produces 450-500 lumens initial emergency 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 DCB-500-LP emergency ballast. This emergency ballast shall consist of a high-temperature, maintenance-free nickel cadmium battery, charger and electronic circuitry contained in one 14.2” x 1.1” x 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 one (1) 14W-32W (2’ - 4’) T5 or T8 fluorescent lamps without integral starters at reduced illumination in the emergency mode for a minimum of 90 minutes. The DCB-500-LP shall produce 450 to 500 lumens initial emergency light output, have 2.5 Watts of input power, a 9 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 Five year warranty on all electronics and casing.
