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.

NOTE: Main lamp head wires may vary in color. Instead of WHITE (+), BLACK (-), and GREEN (Ground),

wires may be BROWN (+), BLUE (-), and BLACK (Ground) respectively.

2. Flush ECD with water under line pressure (typically 30 to 75 psi). Discard the drain or breather if the

foreign material is not removed.

NOTE: Different styles and sizes of ECD fittings will allow different amounts of water or air to pass

through. To determine if a breather or drain has been cleaned, compare the volume or water passing

through a clean, unused breather or drain of the same style and size.

3. After cleaning, attach the breather or drain to a pressurized dry air supply line in a similar manner to that

used with the water line in Step 1.

4. Blow the fitting dry, inside and out, with the dry air.

PERIODIC TESTING

Article 700 of the National Electrical Code states, “Systems shall be tested periodically on a schedule

acceptable to the authority having jurisdiction to assure their maintenance in proper operating condition.” It

also states, “A written record shall be kept of such tests and maintenance.”

In the absence of periodic testing requirements by a local authority, the following recommendations from the

NFPA 101 (2003) Life Safety Code®are strongly recommended:

1. Monthly: Momentarily operate push-to-test switch. Observe that emergency lighting fixtures are on full

brightness for the entire test cycle. Record the test on the Maintenance Record Card (provided on page

5).

2. Annually: Shut off AC power at the distribution panel. Verify that the emergency lighting fixtures remain

“ON” for a minimum of 1 1⁄2hours.

NOTE: Leave the battery disconnect switch “ON” during this test so that battery circuit is not

interrupted. We suggest that this test be continued until the power supply automatically shuts the

emergency light(s) off. This will help maintain full battery capacity.

Record the test on the Maintenance Record Card.

Allow 72 hours charging time before depending on the battery to operate at full capacity.

Failure to function properly in either test may indicate the need for battery or lamp replacement.

BATTERY REPLACEMENT

1. Turn battery disconnect switch to “OFF” and lock-out the switch.

2. Loosen (do not remove) the captive cover screws (6) of the N2LPS SS power supply housing and carefully

place the cover aside for reassembly later.

3. Disconnect the wire nut attaching black negative lead from battery to the battery plug.

4. Disconnect the wire nut attaching red positive lead from battery to battery disconnect switch, taking care

not to touch the ground.

5. Remove the four (4) screws that fasten the battery hold-down bracket to the mounting plate. Remove

battery. Retain hardware for use with replacement battery.

6. Reinstall new battery using hold-down bracket and four (4) screws previously removed.

7. Reconnect black and red battery conductors using wire nuts.

8. Close cover and torque all cover (6) screws to 21-25 in.-lbs.

9. Unlock designated disconnect switch to “ON” position. You may lock switch in “ON” position to prevent

unauthorized persons from turning system “OFF.”

10. Test replacement battery following Step 3 of Section C, “Complete Installation.”

C. 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.

3. Test emergency lighting system for proper operation (see Table 1 on page 1 for detail indication logic):

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.

4. Allow 72 hours charge time before depending on battery to operate at full capacity.

NOTE: Lock in ON position to prevent unauthorized persons from turning system OFF.

INSPECTION OF BREATHER/DRAIN

The breather/drain is installed to provide ventilation to minimize condensation and also allow liquids to

drain out. Perform visual and mechanical inspections on a regular basis. Frequency should be determined

by the environmental conditions. However, it is recommended that checks should be made at least once per

year.

1. Remove drain or breather and replace it with either a plug or clean drain or breather.

2. Clean breather/drain by following “Flush-Cleaning” instructions.

FLUSH-CLEANING

Flush-Cleaning may be required by the user’s periodic maintenance program or when a drain or breather

becomes clogged with foreign material.

1. Attach drain or breather to a clean water line with threaded end facing upstream (see Figure 4).

WARNING

To avoid electrical shock, use fixture only on systems with an equipment grounding conductor.

WARNING

To avoid potential explosion, do not short circuit the battery or connector terminals.

To avoid explosion:

1. Exercise care in handing cells/batteries in order to prevent shorting of the cell with conductive

materials such as rings, bracelets, and keys. The cell or conductor may overheat and cause burns.

2. Do not dispose of the cell/battery in open flame; cells may burst.

3. Do not open or mutilate cell/battery. Opened cells may release corrosive electrolytes which may

have harmful effects on the skin and eyes, and may be toxic if ingested.

WARNING

NOTE

Unit needs to charge for 72 hours before conducting any tests. Do not disconnect AC power until

unit is fully charged.

CAUTION

To minimize condensation, never disassemble breather or drain assemblies.

CAUTION

To avoid damaging breather/drain, do not force handle or cap during inspection.

Figure 4

FIXTURE HEAD REPLACEMENT

1. Disconnect AC power by opening the supply circuit at the distribution panel.

2. Disconnect DC power by turning designated disconnect selector switch to “OFF.”

3. After removing all AC and DC power to the fixture, loosen (do not remove) the captive cover screws of

the N2LPS SS power supply enclosure and carefully place the cover aside for reassembly later.

4. Disconnect battery lead from charger board.

5. Disconnect fixture head wire leads, noting color coding of wires.

6. Remove nut from underside of fixture head threaded stem and remove fixture head/CGB fitting

assembly from the power supply housing.

NOTE: Do not discard the nut, which will be used with the replacement fixture head.

7. Insert wiring for new fixture head assembly through the power supply opening, and insert the fixture

CGB fitting.

8. Install the nut (removed in Step 6) while holding the fixture head assembly in the desired position.

MAINTENANCE

1. Conduct periodic testing in accordance with local authority and Periodic Testing section of these

instructions.

2. Clean fixture lens and exterior surfaces periodically. We recommend every three months or more

frequently, if appropriate.

3. Frequent interior inspection should be made. A schedule for maintenance check should be determined

by the environment and frequency of use. It is recommended that it should be at least once a year.

4. Perform visual, electrical, and mechanical checks on all components on a regular basis.

• Visually check for undue heating evidenced by discoloration of wires or other components,

damage, or worn parts, or leakage evidenced by water or corrosion in the interior.

• Electrically check to make sure that all connections are clean and tight.

• Mechanically check that all parts are properly assembled.

5. Do not attempt field replacement or repair of N2LPS SS power supply cover gasket. Instead, remove

damaged gasket and continue to use cover without gasket. This will assure safety for use in Class I and

Class II hazardous (classified) locations. However, the enclosure will not be raintight.
