IMPORTANT: Provide each unit with a single-phase AC un-switched power supply from a circuit used for normal lighting.
“UVOLT” product versions operate from 120 volts through 347 volts. All other versions operate from 120 volts through 277 volts.

PRODUCT DAMAGE WILL OCCUR IF THE RATED INPUT VOLTAGE IS EXCEEDED.
NOTE: The battery must be connected to the charger board prior to applying AC power to the unit. Battery damage may occur if

the battery is connected longer than 24 hours without continuous AC power provided. See also “Important Battery Information”,
page 4.

NOTE: The maximum mounting height of ELM2L from ground is 11.7 feet, to meet the minimum illumination requirements of NFPA
101 (current Life Safety Code).

NOTE: Do not connect battery or power unit until remote units (if applicable) are fully connected and wires are isolated from other
potentials (i.e. remote wires shall be isolated from earth ground).

INSTALLATION and WIRING

JUNCTION BOX MOUNTING

-Some details shown below may vary-

On the mounting plate, remove the

1

round center knockout and the desired
pair of keyhole junction box knockouts.

Mounting Plate:

4-3/8”

7”

Route leads through the center

2 3

opening and use code-approved
connectors to make the connections.
(See Wiring Diagram, page 3). Dress
wires and connectors inside junction
box. Units with Remote Lamp Wires:
If no remote lamps are connected,
remote lamp leads (+ and - low voltage
DC) should be left capped and dressed
in mounting plate as shown.

3-1/4”

Junction boxes accommodated:

4” Square

4” Octagon

3-1/2” Round or Octagon

Single Gang Box

Taking care not to pinch wires or
connectors dressed inside junction
box, secure mounting plate to
junction box screws.
NOTE: To ensure proper
engagement of the mounting plate
latches to the housing, DO NOT
OVER-TIGHTEN THE SCREWS.

CONDUIT SURFACE MOUNTING

NOTE: to avoid interference with components in the housing, use the most compact wire connectors appropriate to the wire gauge.

At upper center of the mounting plate,

1

remove the conduit connection
knockout. Also remove at least three
keyhole knockouts. Attach conduit and
secure mounting plate to wall surface
using fasteners with a minimum pullout
rating of 30 lbs. each.

Figure-2

Figure-3

See Wiring Diagram, page 3. Make

2 3

code-approved wire connections to
the AC power supply, and remote
lamps (if applicable). Dress wires
into slots so that the connectors are
secured as shown in Figure 2 or
Figure 3.

Orient conduit fitting so that

all portions of it clear the

edge of the knockout

Secure wire connectors near the
center or near the upper latches

Remove U-shaped knockout from
top center of housing. Hint: Use a
pair of wire cutters first to start a cut
in the thick portion at each side of
the knockout, then finish breaking it
out with pliers.

Cut

Use washer (Grainger
conduit fitting and rear housing if
conduit fitting interferes with battery.

TESTING and MAINTENANCE

NOTE: Emergency lighting systems should be tested in
accordance with NFPA 101 or as often as local codes
require, to ascertain that all components are operational.

NOTE: Allow batteries to charge for 24 hours before initial
testing.

Manual testing:

If the batteries are sufficiently charged, either press and release
the “TEST” button or use the ELA LRT (remote tester accessory
for SDRT units only) on the bottom of the unit to activate a 30­second test, during which the lamps will turn on. After a unit’s
first 30-second test is complete, a test in progress may be
cancelled at any time by pressing and releasing the “TEST”
button again.

Self-Diagnostics (SDRT feature)

Units with this option automatically perform a 5-minute self­diagnostic test of the charging electronics, battery, and lamps
every 30 days, and a 90-minute test every year, indicating
system status as shown in the table at right. First self test
occurs after 15 days of continuous AC Power.

Postponing a self-test:

If an automatic self-test occurs at a time when it is not desirable
for the unit lamps to be on, it can be postponed for 8 hours
either by pressing and releasing the “TEST” button or by using
ELA LRT (remote tester accessory).

IMPORTANT BATTERY INFORMATION:

Batteries are perishable items. For best results, it is
recommended that the batteries receive an initial charge within
the first six months of the manufacture date of the fixture. The
manufacture date can be found on the outside of the unit
packaging and on the product label as part of the Date Code /
Series. The first two digits in the date code represent the year
and the second two digits represent the month. In many cases,
batteries beyond the initial charge recommendation time frame
will recover if fully charged soon after installation. If such a
battery does not recover after a full initial charge, it should be
replaced.

Unit Status Indications

The “TEST” button illuminates to indicate the following conditions:

Indication: Status:

Off Unit is off

Flashing green

Solid amber Battery is charging

Solid green

Flashing R / G

1x red flashing Battery failure (SDRT only)

2x red flashing Lamp failure (SDRT only)

3x red flashing Charger / electronics failure (SDRT only)

Unit is in Emergency operation or Test

Battery is fully charged
Manual test, battery not fully charged (SDRT

only)

Cancelling emergency operation:

Press and hold the “TEST” button for several seconds or
activate using the ELA LRT (remote tester accessory), during
which the status indicator will flash until the lamps turn off. This
restores the AC Reset state in which the unit is shipped.

Load-Learning feature:

Self-Diagnostic units automatically ‘learn’ their total connected
lamp load during the first scheduled self-test (~15 days). The
load-learning function can also be initiated manually by
pressing and holding the “TEST” button for 7 seconds (count
flashes), during this period the lamps will turn on. After 7
seconds, release the button, the lamps will turn off within 2
seconds indicating load learn complete. If lamps stay on longer,
load learn was not successful. This manual load-learning
feature should be initiated whenever the total connected lamp
load of the unit is changed, or a lamp is replaced.

NOTE: Manual load-learning functions cannot be initiated if
there is inadequate charge in the batteries. If this is so, wait
until the unit indicates full battery charge (solid green status
indication) before initiating the manual load-learning function.

Clearing a failure indication:

After a failure condition has been corrected and power is
restored to the unit, clear the failure indication either by
pressing the “TEST” button once or by activating remote Test
option once.

Flashing R/Amber Unable to charge

Solid Red Battery is disconnected

Remote Test (SDRT):

Units with the self-diagnostics/remote test feature allows
manual test activation using a laser pointer. Aim the laser
beam straight onto the circular area labeled near the “TEST”
button for a few moments to activate a 30-second test. (See
also “Manual testing”) A test in progress may be cancelled by
aiming the beam at the test area again. NOTE: The remote
tester should not be used to initiate the Load Learning feature.
