Product Summary
Application
The 503441 universal input (120-277 V) emergency LED driver works in conjunction with an
AC LED driver that has an output current not to exceed 3.0 A. The emergency driver consists
of a high-temperature nickel-cadmium battery, charger and electronic circuitry in one case. The
503441 can deliver up to 10 watts to an LED load (measured at nominal battery voltage) for 90
minutes. If used in an emergency-only fixture, no AC driver is necessary. The 503441 is suitable
for indoor and damp locations. For more information about specific LED and AC driver
compatibility, please call the factory.
Operation
When AC power fails, the 503441 immediately switches to the emergency mode, operating the
LEDs at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the
emergency driver automatically returns to the charging mode. A patented circuit delays AC LED
driver operation for up to 5 seconds to prevent over current of LED's that would occur if both
drivers supply the load at the same time.
Installation
The 503441 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 driver. The emergency driver must be fed from the same branch circuit as the AC
driver. Per UL requirements, the polycarbonate 503441must be enclosed if remote mounted outside of
the fixture. Installation is not recommended with fixtures where the ambient temperature
may fall below 0° C. The product is suitable for installation in sealed and gasketed fixtures.
For LED loads rated less than 30V, connect the load select per Table 1 for proper operation and
optimum performance.
*503441 is field installable when used with the Philips EvoKit G2 LED Retrofit luminaire. Option B
contains the illuminated test switch wiring in its own conduit, with the test switch and a wall plate
included in a separate parts kit.
UL and Code Compliance
The 503441 has been tested by Underwriters Laboratories in accordance with the standards
set forth in UL 924, “Emergency Lighting and Power Equipment,” and is UL Recognized for
factory installation only. Emergency illumination time exceeds the National Electrical Code (NEC),
Life Safety Code (NFPA-LSC) and UL 90-minute requirements.
