III. Trouble-Shooting and Maintenance
CAUTION: Always turn AC power to the equipment OFF before servicing. Servicing should be
performed only by a qualified service technician.
I. Trouble-Shooting
1. Problem: Emergency lights do not operate.
If the charge indicator light is OFF, check
that the circuit breaker for AC supply is ON.
If the charge indicator light is OFF, check
that they battery is properly connected. If the
problem persists, replace the battery.
2. Problem: Emergency lights are dim.
The battery might not be fully charged. Allow
battery to recharge for 24 hours and then
retest. If the lights are still dim, replace the
battery.
II. Maintenance
1. Battery: The battery supplied in the fixture
requires no maintenance. However, it should
be tested periodically and replaced when it
no longer operates the connected fixtures
for the duration of a 30-second or 90-minute
test.
2. Other: Clean lenses and replace lamps as
and when required.
Charger/Battery Fault
LED
Self-Testing: The circuit continuously monitors the operating condition of the AC power, battery supply voltage,
emergency lamp continuity and charging circuit. The purpose of this option is to provide visual signaling in
response to a fault at the EXIT sign battery and/or battery charger. If a failure is detected, visual status will
occur immediately via the CHARGER LED and/or the BATTERY FAULT LED. The LEDs will stay illuminated
until the fault is corrected. The circuit also monitors the transfer circuit as well as performing automatic code
compliant testing. The circuit will perform a 30 second discharge and self-test every 28-30 days. A 90 minute
discharge and self-test is performed every 6 months.
