SmartSet™ Time Records typical occupancy patterns. Using this history
Delays (which is constantly updated), it chooses an optimal
time delay from 7 minutes (when space is usually
vacant) up to 30 minutes (for times that show heavy
usage). SmartSet behavior starts immediately, and
is refined continually as history is collected.
Fixed Time Delay DIP switch selections provide fixed time delays of 5,
10, 15, 20, 25 or 30 minutes.
Auto On Mode The OS300S will turn lights ON and OFF automatically
based on occupancy. If the lights are turned OFF
manually, automatic-ON operation will not be
reenabled until no motion is detected for five minutes.
This feature prevents lights from accidentally being
turned ON after they were deliberately turned OFF.
Manual On Mode Occupants must turn ON the lights by pressing the
Auto-ON/OFF button. The sensor will then keep the
lights ON until no motion is detected for the selected
time delay period. There is a 30 second reset delay.
If motion is detected during this time, the sensor will
turn the lights back ON automatically. After the reset
delay time has elapsed, the Auto-ON/OFF button must
be pressed to turn the lights ON.
Button Override The lights can be turned ON or OFF by pressing the
Auto ON/OFF button, regardless of the operating
mode.
Turning The Lights On

UNIT DESCRI TION AND O ERATION
The OS300S is a passive infrared wall switch that turns lighting ON and OFF
based on occupancy and ambient light levels. SmartSet™ technology allows
the sensor to be installed without any adjustments. This technology allows the
sensor to automatically adjust to the usage patterns in the space. Alternate
operating modes, selected by DIP switch settings, can be combined to create the
ideal custom control.
Time Delays
The OS300S time delay holds the lights ON until no motion is detected for a time
period of 5 seconds to 30 minutes, at which point it turns the lights OFF. The
sensor can automatically select the time delay, or the user can choose a fixed
delay.

Walk-Through Use for rooms that have frequent walk-through traffic
Mode (ie. room that accepts mail deliveries). The OS300S
turns the lights OFF three minutes after the area is
initially occupied, if no motion is detected after the
first 30 seconds. If motion continues beyond the first
30 seconds, the set time delay applies.
Test Mode To test the sensor, a short time delay of 5 seconds is
set as the default (SmartSet/Test). Test Mode cancels
automatically after five minutes, or if a fixed time
delay is selected. To restart the Test Mode, change the
time delay switch setting to any fixed amount and then
return it to the SmartSet/Test setting.
Alerts
The OS300S can provide alerts as a warning before the lights turn OFF.
Light Level Control
Visit our website at: www.passandseymour.com
Sensitivity Adjustment
The OS300S constantly monitors the controlled environment and automatically
adjusts to avoid common ambient conditions that can cause false detections,
while providing maximum coverage.
Light Level Control Lights are held OFF, even when the controlled area is
Enabled occupied, as long as the ambient light level is greater
than a chosen threshold level. The light level can be
set with the overhead lights ON or OFF.
High Default setting. Suitable for most applications.
Low Reduces sensitivity by approximately 50%. Useful in
cases where the sensor is detecting movement outside
of the desired area (also consider masking the lens)
and where heat sources cause unnecessary activation.
Light Flash Alert Lights will flash OFF for one second, one minute
before they will be turned OFF by the sensor.
Audible Alerts Sensor will “chirp” twice, at one minute and at
30 seconds before turn-OFF. A distinct alert will sound
10 seconds before the lights go OFF.
Dual Alerts When both Light Flash Alerts and Audible Alerts are
selected, the Audible Alert at one minute remaining
is replaced by the Light Flash Alert.
No Alerts No warning will be provided.

TROUBLESHOOTING
Lights will not turn ON (LED does flash):
1. Press and release the button. If the lights turn ON, verify that the correct
On Mode is selected in the DIP switches.
2. Check all wire connections, in particular, the Load connection.
3. Check to see if light level control is enabled and natural light is holding
OFF light. Test by holding hand over the sensor lens.
4. If lights still do not turn ON, call 800.223.4185 for technical support.
Lights will not turn ON (LED does not flash)
1. Check the wire connections, in particular, the Ground and Line
connections. Verify that connections are tightly secured.
2. Press and release the button. If the lights turn ON, verify that the
Sensitivity is set to igh/Auto.
3. If lights still do not go ON, call 800.223.4185 for technical support
Lights will not turn OFF
1. There can be up to a 30 minute time delay after the last motion is
detected. To verify proper operation, place the unit in any Fixed time delay
(any of switches 1, 2, or 3 in the ON position), then select Automatic time
delay (switches 1, 2, and 3 in the OFF position) to temporarily reenable
Test Mode. Move out of view of the sensor. The lights should turn OFF in
approximately 15 seconds.
2. Verify that the sensor is mounted at least six feet away from any
heating/ventilating/air conditioning device that may cause false detection.
Verify that there is no significant heat source (e.g., high wattage light bulb)
mounted near the sensor.
3. If the lights still do not turn OFF, call 800.223.4185 for technical support.
Sensing motion outside desired areas
1. Select Sensitivity – Low (dip switch 4 = ON) if necessary.
2. Mask the sensor’s lens, using the opaque tape supplied, to limit the field-
of-view to the desired area.
No response to repeated button presses
Rapid pressing of the Auto-ON/OFF button will cause a delay in proper
functioning of sensor. If the sensor does not respond to pressing the Auto
ON/OFF button, wait for 10-15 seconds, and then press the button once again

COVERAGE ATTERNS
The OS300S will cover up to 300 sq. ft. The typical recommended coverage for
desktop activity is 150 sq. ft. The sensor has a two-tiered, multi-cell viewing
Fresnel lens with 180 degree field of view.

Masking the lens
Opaque adhesive tape is supplied so that sections of the sensor’s view can
be masked. This allows you to eliminate coverage in unwanted areas. Since
masking removes bands of coverage, remember to take this into account when
troubleshooting coverage problems.

1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect the existing wires to the sensor terminals.
• ot or Black to Line; Load or Red to Load; Ground or Green to Ground
• Do not allow bare wire to show above connector.
• The ground wire must be tightly fastened or the unit will not operate
properly.
• If the metal junction box is grounded, attachment of the strap (by screws)
to the junction box can constitute a suitable ground. Assure that the green
ground screw on the sensor is completely tightened.
3. Attach the sensor to the wall box by
inserting screws into the two wide
holes on the top and bottom of the
attached metal bracket. Match them
up with the holes in the wall box and
tighten.
4. Turn circuit breaker ON. Wait one
minute, then push the auto/OFF switch
and the lights will turn ON. There is a
delay due to initial power-up of the
sensor that only occurs during
installation.

ADJUSTMENTS
Sensor Adjustment
Your OS300S has been preset for optimum performance at the factory. It is
designed with SmartSet technology for “Install and Forget” functionality. If you
need to change the settings follow the directions below.
All major adjustments to the OS300S must be made with the wall plate
removed. To access DIP switches, remove the button cap by squeezing the top
sides of the button and pull it gently away from the unit.
When the adjustments are completed, replace the button by inserting its hinges
into the LED light bar and then squeeze the top of the button while pressing it
into the unit. Reinstall the cover plate.
Light Level Adjustment
To set, or reset, the threshold to match a current ambient light level, put the
sensor into TEST mode. Press and hold the button for 3 seconds, until a beep is
heard, then step away from the sensor. After 25 seconds another short beep will
sound, indicating that the threshold level has been set. This threshold will be
retained, even if power is lost, or Light Level Control is temporarily disabled,
until it is re-programmed in this manner.
Automatic Reset
olding the On/Off button for ten seconds will cause the OS300S to reset to
default settings. This includes resetting the light level threshold to maximum
(i.e. even the brightest ambient light will not hold the light OFF). The sensor
occupancy history is also reset.
