S72T
THIN SERIES
FOR STANDARD T5 LAMPS
APPLICATION
The S72T ''THIN'' fluorescent emergency ballast works in conjunction with a low-profile AC ballast to convert new or existing standard T5 fluorescent fixtures into unobtrusive emergency lighting. The emergency ballast consists of a high-temperature nickel-cadmium battery, charger and electronic circuitry in one compact case. The S72T can be used with 14 W through 28 W T5 fluorescent lamps, and is compatible with most electronic and dimming AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. The S72T is suitable for use in indoor-dry locations EXCEPT air handling heated air outlet fixtures, and wet, damp, or hazardous location fixtures. For information about specific lamp and ballast compatibility, please call the factory. Recommended applications include: emergency lighting for pendant, cove, recessed indirect/direct, surface-mount, and architectural lighting commonly used in office, hospitality, health care, retail, and educational facilities.
OPERATION
When AC power fails, the S72T 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 emergency ballast automatically returns to the charging mode and delays AC ballast operation for five seconds to prevent false-tripping of AC ballast
(end-of-life) shutdown circuits.
INSTALLATION
The S72T 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 S72T should be installed inside the fixture. Installation is not recommended with fixtures where the ambient temperature may fall below 0°C.
UL and CODE COMPLIANCE
The S72T has been tested by Underwriters Laboratories in accordance with the standards set forth in UL924 - "Emergency Lighting and Power Equipment," and is UL Listed for factory installation or field retrofit. Emergency illumination time exceeds the National Electrical Code (NEC), Life Safety Code (NFPA-LSC) and UL 90-minute requirements.
BATTERY
Since high temperatures exist in fluorescent fixtures, the S72T 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
SPECIFICATION
Emergency lighting shall be provided by using a standard fluorescent fixture equipped with a SIDE-LITE S72T
''THIN'' emergency ballast. This emergency ballast shall delay AC ballast operation for five seconds to prevent false-tripping of AC ballast end-of-life shutdown circuits, and consist of a high-temperature, maintenance-free nickel-cadmium battery, charger and electronic circuitry contained in one 18.5" x 1.18" x 1.0" galvanized steel 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 fluorescent lamp at lumens (see Table 1) initial emergency light output in the emergency mode for a minimum of 90 minutes. The S72T shall have 1.5 Watts of input power, a 10.8 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 the fixture, warranted for a full five years from date of purchase, and made in the U.S.A..
WARRANTY
Model S72T is warranted for five (5) full years from date of purchase. This warranty covers only properly installed Side-Lite emergency ballasts used under normal conditions. For the warranty period Side-Lite 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.| Product Summary | |
