Field of View Adjustment
If the sensor is “seeing” out
through a doorway into a hallway
or “seeing” undesired areas, simply
cover part of the sensor lens with
opaque white tape or a paper label.
Clear tape may be used, but it limits
detection only partially. Test that the
portion of the lens covered limits
detection as desired and does not
reduce detection in other areas.
Removing the Adjustment
Access Cover:
This cover is tamperproof and can
not be removed if the switch cover
Plate is attached. The cover has two
“ears” that hook under the cover
plate and prevent tampering. To
remove the cover insert a screw-
driver into the latch and pull forward.
Time Delay Adjustment
The time delay adjustment can be
set so the lights turn off from 8
seconds minimum to 15 minutes
maximum after the room is vacated
(approximate).
Walk Test
To test the detection pattern of the
LOS800, make no motion for 30
seconds. Move sideways up to 12”.
The red LED flashes once every 4
seconds when turned on initially
and twice every second to show
detection.

Lights do Not Turn On
1. Check that:
•
the lamps and fixtures work;
•
wiring exactly matches the
wiring diagram;
•
wiring polarity is correct;
•
power is on;
•
sensor has warmed up for 3
minutes;
•
off/auto switch is not OFF
2. Make sure sensor’s view of the
room is not blocked
Lights do Not Turn Off
1. Check that the Time delay control
is set to minimum.
2. Stay completely out of the protec-
tion pattern to avoid activation.
3. Make sure sensor is not seeing
movement in an adjacent area
through a doorway or other opening.
4. Make sure unit is not aimed at
something that would move or cause
a temperature change such as hot
water pipes, air conditioners or
heating vents.
5. Check that the wattage controlled
does not exceed the maximum limits.
Lights Go On and Off Quickly
1. Check that wattage controlled
does not exceed maximum limits.
2. Certain energy saving fluorescent
lamps strobe when turned on within
a minute of being turned off.
Lights Go On for “No Reason”
1. Look for sources of electrical
noise such as fans or air conditioners
on the same circuit or nearby. If
possible, unplug or move the noise
sources.
2. Check if sensor is “seeing” into
adjacent rooms or hallways. Mask
sensor lens in that direction with
opaque tape.
3. Check if sensor is “seeing”
heaters or air conditioning vents.
Mask sensor lens if necessary.
4. Make sure unit is at room temper-
ature. If it was installed immediately
after being in an extremely hot or
cold environment, wait an hour for it
to adjust.
