LOS-SIR-6 08.09.05
Occupant Sensors
LOS-SIR Series
Sensors
Installation
Mounts as a direct replacement for a standard wall switch.
1. Warning: Turn power OFF at circuit breaker or remove fuse.
2. Remove switch mounting screw. (Turn screws counterclockwise.) Pull switch from wall.
3. Disconnect switch wires.
Scr
ew Terminals: Turn screws counterclockwise to loosen.
Backwired: Insert screwdriver and pull wire out.
4. Wire the switch by referring to the appropriate Wiring Diagram.
5. Mount and align switch. Replace wallplate.
6. Turn power ON.
Note: Lights may not come on when first powered up.
Allow 60 seconds warm-up for device to reach normal operation.
Adjustments
1. Remove the cover located between the sensor lens and the push button by inserting a small flathead
screwdriver into the notch located on the top of the cover. Gently lift the screwdriver upward to unlatch
cover. For HD models, the cover is at the top of the switch; slide it upward to remove.
2. T
ime Delay: Turn the adjustment on the left labeled “T” fully counterclockwise to the minimum setting (30
seconds). This must be set at the minimum while testing the sensor and adjusting the photo cell and
sensitivity settings. Turning the adjustment fully clockwise puts the unit into bypass, which keeps the light
on regardless of occupancy conditions.
3. Sensitivity:
The sensitivity adjustment is in the center and marked “S”. Adjust the sensitivity to avoid
unwanted detection, such as hallway traffic or adjacent movement. Turn the setting counterclockwise to
decrease sensitivity, clockwise to increase sensitivity.
4. Photo Cell:
The photo cell is used to detect if other light sources, such as sunlight, are enough to
illuminate the space without turning on the lights. If use of the photo cell is desired, see the Photo Cell
Adjustments below. If use of the photo cell is not desired, turn the photo cell adjustment (located on the
right, labeled “A”) fully clockwise to the maximum setting. This will allow the sensor to turn the light on
and off regardless of ambient light conditions
5. Vacate the room until the lights turn off.
Photo Cell Adjustment (except LOS-SIR-M)
1. Adjust the room lights to the same level for which you want the sensor to turn on (use the blinds,
shades, etc.).
2. Set the time delay to the minimum setting by turning the adjustment fully counterclockwise.
3. Turn the ambient control setting fully counterclockwise. Leave the room and allow the lights to turn off.
4. Re-enter the room and slowly turn the ambient control clockwise until the lights switch on.
NOTE: Avoid blocking the lens and sensor while making this adjustment.
5. Ambient threshold is now set at the ambient light level present at the sensor.
