4. MOUNTING THE TEST SWITCH / CHARGE INDICATOR
For installation of the
Test Switch / Charge Indicator,
select a convenient location on the fixture so the
Test
Switch / Charge Indicator
can be seen after installation. Allow for proper clearance inside the fixture and drill or
punch a
1
/
2
″ hole. Remove the nut from the
Test Switch / Charge Indicator
. Push the
Test Switch / Charge In-
dicator
housing into the
1
/
2
″ hole and secure with the nut. Connect the LED wires from the unit to the
Test Switch
/ Charge Indicator
as indicated in the wiring instructions. If needed, a plastic tube is provided to run the
Test
Switch / Charge Indicator
close to the fixture lens for extra visibility. Refer to
Illustrations 1 and 2
.
5. LABELS
Attach the appropriate labels adjacent to the
Test Switch / Charge Indicator
.
Annotate Replacement Label with
identical manufacturer part number(s). The Caution and the Replacement labels must be on the fixture in a readily
visible location to anyone attempting to service the fixture.
6. WIRING THE A.C. INPUT
A. The
LEM Emergency Driver
and A.C. driver
MUST
be on the same branch circuit.
B. The
LEM Emergency Driver
requires an
unswitched
A.C. power source of 120 to 277 volts, 50/60Hz; there
-
fore when used with switched fixtures, the
LEM Emergency Driver
input must be wired ahead of the switch.
C. Refer to the wiring diagram for proper wiring. For wiring diagrams not shown, consult our customer service.
7. COMPLETING INSTALLATION
When the installation is complete, join the
LEM Emergency Drive
r unit connector and then supply AC power.
OPERATION
Normal Mode
– A.C. power is present. The A.C. driver operates the LED load as intended. The
LEM Emergency Driver
is in the standby charging mode. The
Test Switch / Charge Indicator
will be lit providing a visual indication that the bat-
tery is being charged.
Emergency Mode
– The A.C. power fails. The
LEM Emergency Driver
senses the A.C. power failure and automati-
cally switches to the
Emergency Mode
. The designated LED array will illuminate for a minimum of 90 minutes. When
the A.C. power is restored, the
LEM Emergency Driver
switches the system back to the
Normal Mode
and resumes
battery charging. See page 1 of the Instruction Manual.
TESTING & MAINTENANCE
Pressing the
Test Switch / Charge Indicator
turns off the light on the
Test Switch / Charge Indicator
and forces the
unit into emergency mode, interrupting power to the designated A.C. driver. The LED load is now being lit by the
LEM
Emergency Driver
unit. After releasing the
Test Switch / Charge Indicator
, the fixture returns to normal operation after
a momentary delay. To simulate a “BLACK OUT” use the circuit breaker to turn off A.C. power.
Initial Testing
– Allow the unit to charge approximately 1 hour, then conduct a short discharge test. Allow a 24 hour
charge before conducting a one hour test.
The
LEM Emergency Driver
is a maintenance free unit, however, periodic inspection and testing is required. NFPA
101, Life Safety Code, outlines the following schedule:
Monthly
– Ensure that the
Test Switch / Charge Indicator
light
is illuminated. Conduct a 30 second discharge test by
depressing the
Test Switch / Charge Indicator
. At least one LED should operate at reduced output.
Annually
– Ensure that the
Test Switch / Charge Indicator
is illuminated. Conduct a full 90 minute discharge test. The
unit should operate as intended for the duration of the test.
“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
