APPLICATION

The ELPS502 model #M05 emergency lighting system is designed to automatically provide illumination to designated areas during failure or interruption of power to the normal lighting system. The ELPS502 is factory assembled and wired, and consists of one ELPS50 power supply and two EVLA lighting fixtures.

When properly installed, the following raintight ELPS emergency lighting systems are UL and cUL Listed for use in:

ELPS50 Power Supply - Class I, Division 1, Groups B, C & D

ELPS502 - Class I, Division 1, Groups B, C, D

Exit sign not UL/cUL

• ELPS502 (EXS/EXD) - Class I, Division 1 & 2, Groups C, D (group B when ordered with GB suffix)

All ELPS emergency lighting systems are suitable for use in Class II, Division 1, Groups E, F, G and simultaneous presence hazardous (classified) areas as defined by the National Electrical Code®.

The ELPS50 power supply consists of a battery supply and battery recharging system housed inside a hazardous area 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" push button switch is provided for periodic testing of the unit.

Detail indication logic is given below:

 

No Light

AC power is removed from circuit

Steady Light (No blinks)

Fully Charged

Light Blinks Once

Charging

• - •

Light Blinks Twice

Battery Failure

• - • - •

Light Blinks Three Times

Circuit Failure

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 ELPS 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 90minute battery discharge test.

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).

The EVLA12 lighting fixture is a factory sealed assembly housing a single halogen lamp/reflector light source. ELPS EVI and ELPS EVA GB Exit Signs are factory sealed with a single incandescent light source. Lamps are included with all fixtures.

The EVLA12 is suitable for NEMA 4X locations when remote mounted (not installed on an ELPS Power Supply) and supplied with a NEMA 4X breather/drain.

EDS2129 (EDS2129GB for Group B applications) - Designated Disconnect Remote

Mounted (not supplied). Install per the instructions supplied with the EDS2129(GB)

disconnect. Wire to terminals 8 and 9. See Step 2c to continue supply wiring.

WARNING

To avoid explosion, a Designated Disconnect position with lock-in/lock-out is required for safe servicing of the completely wired unit. The lock-in/lock-out capability will help prevent unauthorized opening of the circuit when the system should be functioning and to help prevent energizing of the system while it is being serviced, minimizing the possibility of arcing in the battery circuit while the enclosure is open in a hazardous (classified) area.

To avoid explosion, the designated disconnect switch, Cooper Crouse-Hinds EDSC2129 (EDS2129GB for Group B applications) must be suitable for use in the hazardous locations in which it is installed.

2c. Connect 120 VAC primary (through designated disconnect) to terminal 120 (#3). Connect 220/240 VAC primary (through designated disconnect) to terminal 220/240 (#4). Connect 277 VAC primary (through designated disconnect) to terminal 277 (#5). Connect common to terminal COM (#2). Connect all equipment grounding conductors to terminal GRD (#1). Connect battery connector to circuit board. Verify that transformer connector is also connected to circuit board.

WARNING

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

NOTE

In Class II and Class III and Simultaneous Presence locations, limit upward aiming of fixture to a maximum of 30º above horizontal. Greater upward aiming could lead to excessive dust buildup and dangerous overheating of the dust.

NOTE

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

3.Test wiring for correctness with continuity checks and also for unwanted grounds with insulation resistance tester.

4.Allow the ELPS to charge under line power for 72 hours before initiating any testing of the emergency operation of the lights.

D. Complete Installation

1.Install CID101 corrosion inhibitor device (supplied loose in ELPS50). Recommended location is on the bottom wall between “Main Power On” pilot light and 1" NPT tapped hole. Refer to CID101 instructions for installation.

CAUTION

To avoid explosion, clean both flat joint surfaces of body and cover before closing. Dirt or foreign material must not accumulate on flat joint surfaces. Surfaces must seat fully against each other to provide a proper explosion proof seal.

Figure 5. ELPS50 Controls

2.Close cover and securely tighten all cover bolts and nuts to 30 ft. lbs. torque making certain that no cover bolts are omitted. Use only bolts supplied with the enclosure.

NOTE: ELPS units have two stud bolts located at diagonally opposite corners of the body to aid in positioning cover.

NOTE

A Class I, Division 1 sealing fitting must be installed within 18 inches of the conduit entry of the ELPS enclosure. Use Chico A or Chico SpeedSeal sealing compound to seal the conduit entry.

DO NOT depress the push-to-test pushbutton until after the ELPS has been powered for 72 hours. The emergency battery requires 72 hours to fully charge. The indicating light will illuminate steadily (no pulsing) when the ELPS is fully charged.

3.Test emergency lighting system for proper operation:

a.Turn on power to designated disconnect switch.

b.Turn on designated disconnect switch and observe:

“Main Power ON” indicating pilot light should be operating.

EVLA12 emergency light(s) should be “OFF”.

c.Press “Push-to-Test” indicating push button switch and observe:

“Main Power ON” light should be “OFF”.

EVLA12 emergency light(s) should be “ON”.

4.Lock designated disconnect switch “ON” to prevent unauthorized persons from turning system “OFF”.

5.Adjust EVLA12 emergency light(s) for the desired direction of illumination & lock into position using 1-5/8” open-ended wrench & torquing to 58 lb.-ft. See Figure 2.

E. Remote Mounting EVLA12 Emergency Light Only

1.Attach the EVLA12 to a Cooper Crouse-Hinds EABC36 or EABL36 1" NPT outlet box.

2.Secure this assembly to the mounting surface with ¼ inch bolts or lag screws of the required length (not supplied).

3.Refer to Table 1 on page 6 for conductor recommendations.

4.Refer to Sections B for aiming adjustments and section C for Conduit Connections and Wiring.

PERIODIC TESTING

Article 700 of the National Electrical Code states that, “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 that, “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: Operate “Push-to-Test” switch and keep depressed for a minimum of 30 seconds. Observe that emergency lighting fixtures are on full brightness for the full time. Record the test on the maintenance record card. Maintenance Record Card is provided in instruction sheet envelope.

2.Annually: Shut off power at the distribution panel. Verify that the emergency lighting fixtures remain “ON” for a minimum of 1-1/2 hours.

NOTE: Leave the designated 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 48 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.

REPLACEMENT CIRCUIT BOARD & BATTERY KIT

ELPS-K50 KIT CONSISTS OF:

(1) Circuit Board & Charger Assembly with Mounting Bracket

(1) IF- 1510-A Instructions

(1) Sealed Ni-CAD Battery

(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:

NOTE

ELPS series emergency light fixtures were re-designed in October, 2005. Previous models had circuit boards wired to normally closed contacts. This ELPS-K50 kit has a new circuit board that must be wired to normally open contacts. Older units used different style light fixture heads (see Figure 8 below).

 

No Light

AC power is removed from circuit

Steady Light (No blinks)

Fully Charged

Light Blinks Once

Charging

• - •

Light Blinks Twice

Battery Failure

• - • - •

Light Blinks Three Times

Circuit Failure

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 ELPS 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 90minute battery discharge test.

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.

WARNING

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.

MAINTENANCE

WARNING

To avoid explosion always disconnect primary power source using designated disconnect switch before opening enclosure for inspection or service.

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 evidence 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 ELPS50 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 rain tight.

CAUTION

To avoid explosion, clean both flat joint surfaces of body and cover before closing. Dirt or foreign material must not accumulate on flat joint surfaces. Surfaces must seat fully against each other to provide a proper explosion proof seal.

BREATHER AND DRAIN

ELPS50 power supply enclose is provided with breather and drain. Refer to Installation and Maintenance Information IF-843 for inspection and maintenance instructions.

IMPORTANT

A DESIGNATED DISCONNECT SWITCH IS REQUIRED FOR SAFETY, TO POWER THE ELPS502 EMERGENCY LIGHT SYSTEM AND CHARGE THE BATTERIES.

To avoid explosion, a Designated Disconnect switch with lock-in/lock-out capability is required for safe servicing of the completely wired unit. The lock- in/lock-out capability will prevent unauthorized opening of the circuit when the system should be functioning and to help prevent energizing of the system while it is being serviced, minimizing the possibility of arcing in the battery circuit while the enclosure is open in a hazardous (classified) area.

Units supplied with option S794 or Option S854 already have a disconnect switch installed on the enclosure. Standard units require a remote disconnect switch. If the switch is also located in a hazardous area, you must install a Class 1, Div. 1, rated switch. Use Crouse-Hinds EDS2129 or EDS2129-GB (for Group B applications).
