2. Disconnect DC power by turning designated disconnect selector switch to "OFF."
N2LPS K57 KIT CONSISTS OF:
(1) Circuit Board and Battery Assembly with Mounting Plate
(1) IF1595A Instructions
(1) Sealed Ni-Cad Battery (A high temp. rated battery for N2LPS K57 S904 kit included)
(1) 2 Volt LED for Pilot Light
(1) CID101 Corrosion Inhibitor Device
This kit includes a new LED indicating lamp that gives a visual status of the unit. Details
indicating LED logic is given below:
3. Loosen (do not remove) the captive cover screws (6) of the N2LPS power supply
housing and carefully place the cover aside for reassembly later.

Status Description
Table 1. Detail Indication Logic
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 requires 72 hours
to charge the battery. Once the unit has completed charging, the indicating light will stop
blinking and go to steady. Every six months, the unit will automatically perform a 90
minute battery discharge test. 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.
At the completion of the test, if it is determined not to have met the 90 minute requirement,
the indicating lamp will display circuit failure (3 blinks). At any time, if the battery
connection is not adequate, the indicating lamp will display a battery failure (2 blinks).
WARNING
To prevent injury from electric shock, all power must be removed from the fixture
during maintenance.

9. Connect the pilot light, DC disconnect switch, pushbuttons, and lamp heads (see
Figure 2).
10. Connect 120 VAC primary (through designated disconnect) to terminal 120. Connect
230 VAC primary (through designated disconnect) to terminal 230. Connect 277 VAC
primary (through designated disconnect) to terminal 277. Connect common to
terminal COM. Connect all equipment grounding
Disconnect
conductors to terminal GRD.
11. Verify that battery connector and transformer
connector are connected to circuit board. If not,
execute the connections (see Figure 2).

COMPLETE INSTALLATION
1. Install CID101 corrosion inhibitor device (supplied in plastic envelope with instruction
sheet). Recommended location is on the inside surface of the top of the enclosure
near the right side fixture stem. Refer to CID101 instruction for installation.
2. Close cover and torque all cover (6) screws to 21-25 in.-lbs.
Turn on the AC power and observe:
•
•
Indicating light marked “ON” should be operating
Momentarily press the push-to-test button and observe - emergency lights
should be operating
NOTE: If emergency lights do not operate initially, allow battery to charge for at least
15 minutes or more, then repeat the test procedure.

5. Disconnect all incoming connections from terminals.
3. Test emergency lighting system for proper operation (see Table 1 for detail indication
logic):
Even after disconnect, batteries will still be live. To prevent electrical shock and
explosion, take extra care not to touch leads together or to ground.

1. LED does not light
2. LED is blinking twice
2. Verify battery is properly connected to circuit
board
3. After 72 hours, unit is not fully charged (LED
steady) and lamp heads flash
3. Remove leads from pushbutton N/C contacts
and terminate the leads on the N/O contacts
4. LED is blinking three times
4. Verify battery voltage under no load is 13.0V
or higher after 72 hour charge; if less than
13.0V, consult factory for battery replacement;
if more than 13.0V, consult factory for complete
interior replacement, as transformer and/or
circuit board could be responsible
