4. Make sure the sensor is not
“seeing” people in other rooms or
hallways through open doorways.
Mask the lens in the direction of
the door.
5. Make sure line voltage has not
browned out below 110 volts. If
voltage is not adequate sensor will
not operate properly.

Reason
1.
Check items #2, 3 & 4 under Lights
Do Not Turn Off.
Maintenance & Repair
A LOS2500 requires no maintenance
other than keeping the lens area
clean and free of obstructions. Do not
attempt to open or repair the unit-
there are dangerous voltages inside
the case, and no user serviceable
parts. For repair service, follow your
warranty instructions.
Lights do Not Turn On
1.
Check for obstructions between
sensor and area of acitivity.
2.
Check that the bulbs and fixtures
work. Check wiring against
diagram.
3.
Check that the power is on.
4.
Increase sensitivity control to
maximum.
Lights Do Not Turn Off
1.
Check items #1, 2 &3 above.
2.
Make sure there is no motion in the
room for at least 15 minutes. stay
completely out of the protection
pattern to avoid activating the unit.
3.
Check the room for possible
sources of infrared energy
sources within view. Look for
air conditioners, heaters, fans,
concentrated or reflected lights,
moving equipment or machinery
with heat venting fans (computers,
copiers, etc). Move the offending
infrared source, or mask the lens
facing the source to avoid detecion.
Reducing sensitivity will also help.
Troubleshooting
Set-up & Adjustment
Time Adjustment
The LOS2500 allows adjustment
of the delay time from 10 seconds to
15 minutes.
If no movement is detected for the
time period selected, the lights turn off.
The Time Adjustment is factory set for
5 minutes.
The Time should be reduced only in
heavy traffic areas such as hallways,
kitchens, copier rooms, etc. to achieve
maximum energy savings.
Keep the time setting at maximum in
large rooms (over 400 sf).
Sensitivity Adjustment
Adjusting the Sensitivity control
is not normally necessary. It can
reduce detector sensitivity 5%. Less
sensitivity may be desired for smaller
rooms (less than 400 sf).
If the unit is being activated by HVAC
or other infrared sources (other than
people), reducing the sensitivity may
help.

Masking the Lens
If the sensor’s location gives it a view
of other rooms or hallways, lights
will be turned on when movement
is detected in these adjacent areas.
The sensor’s detection zone may be
restricted by covering a portion of
the lens with the masking elements
provided.
Temperature Stabilization
If the sensor was in transit and
subjected to extreme heat or freezing
before installation it may take up to
an hour for the sensor to reach room
temperature and operate normally.
