FEATURES & SPECIFICATIONS
INTENDED USE — Provides a minimum of 90 minutes of illumination for the rated wattage upon loss of
AC power. Ideal for applications requiring attractive unit equipment with quick installation.
CONSTRUCTION — White, compact, low-profile contemporary design. Engineering-grade thermoplastic
housing is impact-resistant, scratch-resistant and corrosion-proof. UL94V-0 flame rating. UV-stable resin
resists discoloration from natural and man-made light sources.
OPTICS — Two 5.4W wedge-based krypton lamps offer 32 percent more light output than standard
incandescent lamps.
Patented, MR24, multi-faceted reflector significantly improves photometric performance – 60 to 100 percent
more light delivered to path of egress.
U.S. Patent No. D484,272
Low-profile, integrated test switch/pilot light. Easily visible bright red status indicator.
ELECTRICAL — Current-limiting charger maximizes battery life and minimizes energy consumption.
Provides low operating costs.
Short-circuit protection – current-limiting charger circuitry protects printed circuit board from shorts.
Dual-voltage input capability (120/277V). Edge connectors on printed circuit board ensure long-term
durability.
Thermal protection senses circuitry temperature and adjusts charge current to prevent overheating and
charger failure.
Thermal compensation adjusts charger output to provide optimum charge voltage relative to ambient
temperature.
Battery: Sealed, maintenance-free lead acid (SLA) provides 12W rated capacity. Automatic 48-hour recharge
after a 90-minute discharge. Low-voltage disconnect prevents excessively deep discharge that can permanently damage the battery. Single-circuit battery connection.
Regulated charge voltage maintains constant-charge voltage over a wide range of line voltages. Prevents
over/under charging that shortens battery life and reduces capacity.
Filtered charger input minimizes charge voltage ripple and extends battery life.
AC/LVD reset allows battery connection before AC power is applied and prevents battery damage from
deep discharge
Brownout protection is automatically switched to emergency mode when supply voltage drops below
80 percent of nominal.
INSTALLATION — Unique track-and-swivel arrangement permits full range of direction of lamp head
adjustment. Universal J-box mounting pattern. Tool-less access for maintenance. Flexible conduit entry
provision on top of the unit. Ceiling mount standard. US Patent No. D473,627.
LISTINGS — Meets UL924, NFPA 101 (current Life Safety Code), NEC and OSHA illumination standards.
Meets all applicable FCC requirements.
WARRANTY — 3-year limited warranty. Complete warranty terms located at:

Note: Actual performance may differ as a result of end-user environment and application.
Specifications subject to change without notice.
