EMERGENCY DRIVER
Refer to the diagram below for the appropriate wiring of the LED load and driver. Install in accordance with the National Electrical
Code and local regulations. For additional wiring diagrams consult Customer Service.
Automatic Testing
The
ILBDW
is designed to automatically test the emergency
function for 60 seconds each month, and
90 minutes every 12 months.
Self-testing works in conjunction with the IPS assembly. Any
detected failures will be indicated by flashing of the three-color
LED. See Table A for diagnosis.
Manual Testing
Manual testing of the
ILBDW
can be performed by pressing
and releasing the IPS test button. Only initiate a manual test
when the IPS status indicator light is GREEN (see
Table A
).
Manual testing lasts 60 seconds and may be cancelled at any
time during the test duration by pressing and holding
the IPS.
Load Calibration
To ensure proper operation, Load Calibration is required whenever the LED load connected to the ILBDW is changed.
Note:
Load Calibration happens automatically 48 hours after the ILBDW is first installed.
If after installation,
the connected LED
load is changed
,
Load Calibration will need to be performed
. This will happen
automatically
48 hours after the ILBDW is
re-initialized (see Maintenance section below). To
manually
initiate Load Calibration earlier, press and hold the IPS button for
20 seconds. After 20 seconds, the LED load will turn off. Release the IPS button. The LED load should turn back on and the IPS
will begin FLASHING GREEN to indicate that the 60-second Load Calibration is commencing. Any failures detected during Load
Calibration will be indicated on the IPS (see
Table A
).
“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.

Maintenance
When performing maintenance on the
ILBDW or the emergency luminaire
, the
ILBDW
battery circuit must be completely pow-
ered down by performing the following steps:
1) Disconnect AC power.
The ILBDW will enter EMERGENCY MODE.
2) Disconnect the battery circuit through one of the following methods:
Method 1:
This can only be performed within the first 30 seconds of EMERGENCY Mode -
Press and hold the IPS button for
approximately five seconds until the LED Module shuts off.
Method 2 (“S” Models Only):
Unplug the IPS
Once all power sources are disconnected from the
ILBDW
and
emergency luminaire
, proceed with required maintenance.
When
maintenance is complete
, reconnect the IPS (if unplugged from Method 2 above) and restore AC power to the emer-
gency luminaire. The AC Activate circuitry will detect the presence of AC power and automatically re-activate the
ILBDW
battery
charging circuit.
