ELPS LIGHT-PAK™ EMERGENCY
LIGHTING FIXTURE SERIES
Installation & Maintenance Information for
ELPS-K50 - Replacement Charger Board and Battery Kit
REPLACEMENT CIRCUIT BOARD & BATTERY KIT
ELPS-K50 KIT CONSISTS OF:
(1) circuit board and battery assembly with mounting plate
(1) IF 1510-A instructions
(1) sealed NiCad 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:
No Light
Steady Light (No Blinks)
Light Blinks Once
• - •
Light Blinks Twice
• - • - •
Light Blinks Three Times
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 90-
minute 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).
To prevent injury from electric shock, all power must be removed from the fixture
during maintenance.
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.
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 in the enclosure. Standard units require a remote disconnect switch. If
the switch is also located in a hazardous area, you must install a Class I, Div. 1
rated switch. Use Cooper Crouse-Hinds EDS2129 or EDS2129GB (for Group B
applications).

Figure 1. Wiring Diagram
ELPS Series Emergency Light Fixtures were redesigned 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 2 below).
REMOVAL OF EXISTING
CIRCUIT ASSEMBLY
(For units made BEFORE
October, 2005).
1. Disconnect branch AC power at circuit
breaker and lockout.
2. Disconnect DC power by turning designated
disconnect key or selector switch to "OFF".
3. After removing all AC and DC power to the fixture, remove all cover fasteners to gain
access to the interior.
To avoid explosion, do not damage the flat joint surfaces. Do not use hammers or
prying tools to open covers. Do not handle covers roughly, or place them on
surfaces that might damage or scratch the flat joint surfaces.
4. Disconnect wire leads at the pilot light and test button.
5. Disconnect all incoming connections from terminals GRD through L-.
6. Remove the mounting stud and pillar located in the uppermost left corner of the
interior. Remove the three (3) other hold down nuts and lock washers on the
aluminum backplate. Remove the old interior assembly and set aside.
7. Install the new interior assembly using the three (3) remaining hold down nuts and lock
washers removed in Step 6.
8. Replace the old incandescent lamp (or old LED) in the pilot light and replace with the
new 2 volt LED supplied with the new interior assembly.
9. Make all incoming wiring connections following the wiring diagram located in the new
assembly (also see Figure 1) and re-connect the EVLA12 light fixture(s) or EXIT sign
wire leads removed from terminals L+ and L-.
