MOUNTING
The OSW-100 is designed to be mounted to a wall or corner.
Step 1: Install Base Unit
• Determine the location of the sensor according to the detection pattern shown in
Figure 1.
• Screw the base of the mounting bracket to the desired position on the wall as shown
in Figure 2.
• Feed the cable through the hole on the back of the bracket.
• Loosen the screw on the bottom of the sensor and remove the cover.
• Feed the cable through the center hole on the back of the sensor housing.
• Attach the sensor to the mounting bracket.

Step 3: Walk Test
Before beginning test, make certain that the On and Off delay jumpers (located on the
circuit board) are connected in the “A” positions as shown in Figure 4. If they are not,
follow the procedure under the section titled On/Off Delay Settings to rearrange the
jumpers to location “A.” Replace the sensor housing and tighten screw.
Figure 4
The walk test is used to quickly ensure correct system wiring, proper functioning of the
output, and proper orientation/location of the sensor.
• Apply power to the unit and allow 45 seconds for the sensor to warm up. The LED
will blink (long blink followed by short) during warm up.
• When the LED stops blinking, the sensor has had adequate time to warm up and is
now in standby mode (Standby mode is discussed in more detail in the Operation
Mode Section.)
• Walk across the detection zone. The LED will stay lit and the output will be activated
during occupancy detection.
The LED will blink rapidly if the sensor is improperly wired.
NOTICE
ON/OFF DELAY SETTINGS
To adjust the On/Off Delay time intervals or adjust sensor for “Walk Test.”
1. Remove the cover from the sensor.
2. Refer back to Figure 4 to locate the ON/OFF Delay pins and jumpers on the circuit
board.
3. Gently remove the jumpers and reinsert into the desired pins according to the table
below.

Range Adjustment
After installation, the sensor can be manually adjusted to meet the detection needs
of a room.
• Loosen the screw on the mounting bracket and then carefully move the unit to the
desired direction.
• Refer back to the diagram in Figure 1 and adjust the sensor accordingly.
• Once the sensor is orientated in the desired direction, hold the unit in place and
tighten the screw.

OPERATION MODES
The OSW-100 Wall Mount Occupancy Sensor utilizes several operation modes to
eliminate false readings and conserve energy.
Standby Mode
Before any movement is being sensed, the sensor is in standby mode.
When the sensor detects occupancy, the LED light turns on and the sensor switches
to Relay On Delay Mode.
Relay On Delay Mode
This adjustable mode allows the user to choose the time delay before the unit reports
that a space is occupied.
The Relay On Delay Mode allows for energy conservation by bypassing short-term or
faulty occupancies. It is followed by a secondary one minute warning delay.
1-Minute Warning Mode
During this mode, the sensor searches for any movement for one minute past the
Relay On Delay Mode.
If occupancy is detected at any point within that one minute, the output device is
activated and the sensor enters Relay Off Delay Mode.
If occupancy is not detected in that one-minute time frame, the sensor enters back
into standby mode.
Relay Off Delay Mode
During this mode, the sensor’s output is activated for a preset period of time.
Once this preset time interval is up, the output device powers off. However, the relay
off delay timer will reset with each motion detection.
This Relay Off Delay Mode allows for energy conservation by eliminating unnecessary
running of the HVAC system.
Storage and Cleaning
The sensor lens is the most delicate part of the Occupancy Sensor. The lens should
be kept clean at all times, care should be taken when cleaning the lens using only
a soft cloth or cotton swab with water or medical alcohol. Allow the lens to fully dry
before using the sensor. The sensor should be installed or stored in an area of room
temperature between -4 and 140ºF (-20 to 60ºC).
MAINTENANCE
After nal installation of the unit, no routine maintenance is required. The Model OSW-
100 is not eld serviceable and should be returned if repair is needed (eld repair
should not be attempted and may void warranty). Be sure to include a brief description
of the problem plus any relevant application notes. Contact customer service to
receive a return goods authorization number before shipping.
Occupancy detection may be affected if the unit is operated within
radio frequency electromagnetic eld strength of approximately 3
volts per meter, but the performance of the instrument will not be permanently affected.
