I. Installation & Operation
NOTE: The EXP-EMG-EXT line is designed to be surface mounted to flat surfaces such as
walls.
I. Installation
Mounting for this fixture is achieved via
mounting tabs located on the back side
of the light.
The EXP-EMG-EXT explosion proof
emergency self-testing LED fixture is NOT
a factory sealed fixture. Operators will bring
their own rigid conduit to a junction box and
complete their connects. Cap off any hubs
that are not in use.
Both battery legs must be connected
together. This prevents the battery from
draining during storage and transit. DO
NOT CONNECT HIGH VOLTAGE TO
BATTERYLEGS.

II. Self-Diagnostic Test
Once the emergency fixture is properly installed andAC power supplied, the dual color LED
indicator will come ON and the self-diagnostic test function will automatically initiate. The LED
indicates the unit’s status. A STEADY GREEN LED indicates normal service, a FLASHING GREEN
LED indicates the unit is testing, a FLASHING GREEN/RED LED indicates the battery is charging
and a RED LED (in different combinations) indicates a service alert. Refer to the service indication
chart for more details. The LED will be OFF when the unit is in emergency mode.
I. Self-Diagnostic Service
The self-diagnostic function is factory preset
and performs the following:
1. Monitoring of battery, battery charger and
lamps.
2. Self-testing and a 30-second or longer
discharge once every 30 days, after AC
power has been supplied for a minimum of 24
hours.
3. Self-testing and a 30-minute or longer
discharge once every 180 days, after AC
power has been supplied for a minimum of 24
hours.
4. Self-testing and a 90-minute discharge
once every 365 days, after AC power has
been supplied for a minimum of 24 hours.

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 theAC 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.
