EMERGENCY DRIVER CHECK
NOTE: For short-term testing of the emergency
function, the battery must be charged for at
least one hour. The emergency driver must be
charged for at least 24 hours before conducting
a long-term test.
STEP 1:
When AC power is applied, the charging
indicator light is illuminated, indicating the
battery is being charged. When power fails,
the emergency driver automatically switches
to emergency power, operating the LED array.
When AC power is restored, the emergency
driver returns to the charging mode.
STEP 2:
Although no routine maintenance is required
to keep the emergency driver functional, it
should be checked periodically to ensure
that it is working. The following schedule is
recommended:
• Visually inspect the charging indicator
light monthly. It should be illuminated.
• Test the emergency operation of the
fixture at 30-day intervals for a minimum
of 30 seconds. When the test switch
is depressed, the LED array should
operate.
• Conduct a 90-minute discharge test once
a year. The LED array should operate for
at least 90 minutes.
If the luminaire fails any of these checks,
consult service personnel.
