Dual elay PI Wall Switch

UNIT DESC IPTION AND OPE ATION
The OSR300S 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 and automatically adjusts it to
the usage patterns in the space. Alternate operating modes, selected by DIP
switch settings, can be combined to create the ideal custom control.
The OSR300S contains two relays. Dual buttons on the front of the OSR300S
allow the user to control one or two loads independently. Pressing an ON/OFF
button toggles the state of the corresponding relay, turning the load on if it is
currently off, or off if it is currently on. If no motion is detected during the time
delay that is in effect, the load will turn off.
The OSR300S also contains a light level sensor that, when enabled, operates
on the secondary relay. If adequate daylight is present, the sensor holds the
secondary load off until light levels drop, even when the controlled area is
occupied. Users can override this function by blocking the light coming into the
sensor by placing their hand over the sensor lens until the load comes on. The
load will then remain on until the space is unoccupied.
Turning The Load On
The relays are programmed independently for either Auto On or Manual On.
In either mode, the load can be turned on or off using the ON/OFF button.
Auto On Load turns on and off automatically based on occupancy.
If the load is turned off manually, automatic-on is reenabled
when no motion is detected for five minutes. This prevents the
load from being turned on after it was deliberately turned off.
Manual On Occupants must turn on the load by pressing the ON/OFF but-
ton. The sensor keeps the load on until no motion is detected
for the selected time delay. There is a 30 second reset delay. If
motion is detected during this time, the sensor turns the load
back on automatically. After the reset delay time has elapsed,
the ON/OFF button must be pressed to turn on the load.
Time Delays
The OSR300S holds the load on until no motion is detected for the selected
time delay. You select either SmartSet or a Fixed time delay using DIP switch
settings. The sensor automatically sets the time delay when SmartSet is
enabled; with the fixed time delay settings you select a time delay between
5 to 30 minutes, and whether the Walk-Through mode is included.
Both relays use the same delay, unless a delayed disconnect is enabled for relay
2 using the Delay Relay 2 Disconnect feature. This delayed disconnect feature is
useful in applications where you want both loads to turn off automatically, but
want relay 2 to stay on longer, such as when running an exhaust fan after the
lights have shut off.

SmartSet™ Records typical occupancy patterns. Using this history
Time Delays (which is constantly updated), it chooses an optimal
time delay from two minutes (if the space is usually
vacant) up to 30 minutes (if the space gets 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 or 30 minutes.
Walk-Through Mode Use for rooms that have frequent walk-through traffic
(i.e., room that accepts mail deliveries). The OSR300S
turns the load 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 SmartSet or Fixed time delay applies.
Test Mode To confirm proper operation of the sensor, a short
Time Delay initial time delay of 15 seconds is set as the default
(SmartSet/Test) mode. This Test Mode cancels
automatically after five minutes, or if a fixed time
delay is selected. To reenable the Test Mode for an
additional five minutes, change the time delay from
any fixed amount to the SmartSet/Test setting.
Delay elay 2 Both relays use the same Time Delay, unless DIP
Disconnect switch #4 is turned on, enabling a delayed disconnect
for relay 2. When the delayed disconnect is enabled,
relay 2 turns off 10 minutes after relay 1 and during
Test Mode, relay 2 turns off 10 seconds after relay 1.
High/SmartSet™ The OSR300S monitors the controlled environment
and automatically selects the maximum sensitivity
setting that will provide reliable operation without
false detection. This setting is constantly updated.
Low Fixed sensitivity mode, reduces detection range.
Alerts
To warn an occupant that the load is about to be turned off, the OSR300S
provides audible alerts.
Sensitivity Adjustment
Audible Alerts Sensor "chirps" twice – at one minute and at
30 seconds before turn-off. A distinct alert sounds
10 seconds before the lights go off.
No Alerts No warning is provided.

COVE AGE PATTE NS
The OSR300S will cover up to 300 sq. ft. (28m2). The typical recommended
coverage for desktop activity is 150 sq. ft. (14m2). 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 wires to the OSR300S wire leads as shown in the wiring diagrams.
The ground wires must be tightly fastened or the unit will not operate
properly. If the metal junction box is grounded, it can be a suitable ground.
Attach a ground wire to the green terminal as shown.
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 the circuit breaker on. Wait one minute, then push the Auto ON/OFF
switch for each load and the lights will turn on. There is a delay due to initial
power-up of the sensor that only occurs during installation.

T OUBLESHOOTING
Lights do not turn on with motion (LED does flash):
1. Press and release each button to make sure that the correct lights come
on for each relay. If the lights turn on with the button press, verify that the
correct On Mode is selected in DIP switches 5 and 6.
2. Check to see if light level control is enabled: cover the sensor lens with
your hand. If the lights come on, adjust the light level setting.
3. Check all wire connections, in particular, the Load connection.
4. If lights still do not turn on, call 800.223.4185 for technical support.

ADJUSTMENTS
Sensor Adjustment
The OSR300S is preset to SmartSet mode. It is designed for “Install and Forget”
functionality. If you need to change the settings, follow the directions below.
All major adjustments to the OSR300S must be made with the wall plate
removed. To access the DIP switches, remove the button cap by squeezing the
top sides of the button assembly and pull it gently away from the unit.
When the adjustments are completed, replace the button cap 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
The light level setting only affects the secondary relay. The light level can be
set with the overhead lights on or off. To enable light level control and set the
threshold to match the current ambient light level, press and hold the Relay 2
button for 3 seconds, until you hear a beep. Step away from the sensor. After
25 seconds another short beep sounds, indicating that the threshold level is
set. This threshold is retained, even if power is lost, until it is disabled then
re-programmed in this manner. To disable light level control, press and hold
the Relay 2 button for ten seconds, until a beep tone sounds.
eset to Default
Press and hold the Relay 1button for ten seconds to reset the OSR300S to
factory settings. This resets the sensor occupancy history and disables light
level control (the brightest ambient light will not hold the light off).

Catalog # Description
OSR300S Universal PIR Wall Switch; 120/277VAC, 50/60Hz
Lights do not turn off
1. There can be up to a 30 minute time delay after the last motion is
detected. To verify proper operation, set DIP switch 1 to ON, then reset
switches 1, 2, and 3 to OFF to start Test Mode. Move out of view of the
sensor. The lights should turn off in approximately 15 seconds. Relay 2
lights turn off 10 seconds after Relay 1 lights, if DIP switch 4 is ON.
2. Verify that the sensor is mounted at least six feet (2 meters) 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 8 = ON) if necessary.
2. Mask the sensor’s lens, using the opaque tape supplied.
No response to repeated button presses
Rapid pressing of the Auto-ON/OFF button causes a delay in proper
functioning of the sensor. If the sensor does not respond to pressing the
ON/OFF button, wait 10-15 seconds, then press the button once again.
