APPLICATION
The LED N2LPS SS Emergency Lighting System is designed to automatically provide
illumination to designated areas during failure or interruption of power to the normal
lighting system. The N2LPS SS is factory-assembled and wired, and consists of one
battery and two light fixtures.
When properly installed, the following marine rated N2LPS SS emergency lighting
systems are UL and cUL listed for use in:
•
N2LPS12222 SS Power Supply
- Class I, Division 2, Groups B, C, D
•
N2LPS12220 SS Power Supply
- Class I, Division 2, Groups B, C, D; NEMA 4X
The N2LPS SS power supply consists of a battery supply and battery recharging
system housed inside a 316 stainless steel enclosure with all the circuitry to
automatically turn on emergency DC lighting fixture(s) when the normal power
supply fails. A pilot light indicates when normal power is being supplied to the unit. A
“push-to-test" pushbutton switch is provided for periodic testing of the unit.
The light fixture used on the N2LPS SS system is a rugged, epoxy coated corrosion-
resistant assembly, fully adjustable and lockable, and houses a high output MR16
LED lamp, which is included with the fixture.
DETAIL INDICATION LOGIC IS GIVEN BELOW
:
Immediately after supply power is initiated, the indicating lamp will blink/pulse to indicate
that the unit is charging. Once installed with supply power, the N2LPS SS requires 72 hours
to charge the battery. Once the unit has completed charging, the pilot light will stop blinking
and go to steady.
Every six months, the unit will automatically perform a 90 minute battery discharge test. At
the completion of the test, if it is determined not to have met the 90 minute requirement or
if the battery connection is not adequate, the pilot lamp will blink twice, indicating battery
failure. Every 30 days, the unit will also automatically perform a 30 second self-test. If the
battery or board has been compromised the indicator light will blink accordingly.
NOTE:
Ambient temperature at which N2LPS SS power supply is rated is 0ºC to +40ºC
to maximize battery capacity. Ambient temperature at which N2LPS SS S904 is rated
is 0°C to +55°C to maximize battery capacity. Lighting fixtures are permitted in higher,
+55ºC ambient temperature areas for more freedom in selecting remote installation
location.
