DESCRIPTION AND OPERATION
The RS-350-N PIR Dual Relay Universal Application Wall Switch Vacancy Sensor
is designed to replace two single pole standard residential switches or one
combination switch (“double switch”). It is ideal for living and dining rooms, family
rooms, bedrooms, bathrooms and any other indoor area in a residential space
where occupancy sensor-based manual ON/OFF control of two different loads
(i.e., a lamp and a fan) from a single location is desirable.
Like a standard combination switch, you press either or both of the two ON/OFF
buttons to turn lights and/or fans (controlled loads) ON and OFF. Unlike a
standard combination switch, the RS-350-N automatically turns OFF the
controlled loads after the coverage area has been vacant for a period of time
(Time Delay). If motion is detected within 30 seconds after they automatically turn
OFF, the RS-350-N automatically turns the loads back ON.
While the sensor is factory preset as a Vacancy Sensor with manual-ON
operation, it can be adjusted to work as an Occupancy Sensor that turns the
controlled loads ON automatically upon detection of occupancy in the area.
Lighted Switch
To help you locate the RS-350-N in a dark room, an amber LED illuminates
each of the ON/OFF buttons while the controlled loads are OFF. When one of the
controlled loads is ON, the corresponding LED is OFF.
Nightlight
While the controlled load connected to relay #1 is OFF, the nightlight built into the
RS-350-N is ON. When this load is ON, the nightlight is OFF.
Operating Modes
There are two operating modes that can be selected independently for each relay
during set up:
MODE 1 Vacancy sensor (Manual-ON/OFF, Auto-OFF): The user must press the
ON/OFF button to turn the load ON. The RS-350-N keeps the load ON until no
motion is detected for the selected time delay period (adjustable from 15 seconds
to 30 minutes). 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.
MODE 2 Occupancy sensor (Auto-ON/OFF with manual control and reset to auto
after 5 minutes of vacancy): The load turns ON and OFF automatically based on
occupancy detection. The RS-350-N keeps the load ON until no motion is detected
for the selected time delay period. If the load is turned OFF manually, automatic-
ON is re-enabled when no motion is detected for 5 minutes. This prevents the
load from being turned ON after it was deliberately turned OFF.

Time Delay
The time delay can be selected by the user during set up. It can be adjusted from
15 seconds up to 30 minutes and it applies to both relays (hence to both controlled
loads) simultaneously. For additional information on how to adjust the time
delay, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this
installation manual.
Light Level (Relay #1 only)
When relay #1 is set for occupancy sensor Mode 2 (Auto-ON/OFF) the light level
feature prevents the sensor from automatically turning the lights, controlled
by relay #1, ON if there is already enough light in the area. To adjust the light
level, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this
installation manual.
Coverage Area
The RS-350-N has a maximum range of 180 degrees
and a coverage area of 600 sq. feet (56 sq. meters).
The sensor must have a clear and unobstructed view
of the coverage area. Objects blocking the sensor’s
lens may prevent detection thereby causing the load
(or loads) to turn OFF even though someone is in
the area.
Windows, glass doors, and other transparent barriers will obstruct
the sensor’s view and prevent detection.
INSTALLATION & WIRING
WARNING
Disconnect power to the wall switch box by turning OFF
the circuit breaker or removing the fuse for the circuit before installing
the RS-350-N, replacing lamps, or doing any electrical work.
1. Prepare the switch box.
After the power is turned OFF at the circuit breaker box, remove the existing
wall plate and mounting screws. Pull the two old switches or combination
switch (double switch) out from the wall box.
2. Identify the type of circuit.
If you are replacing a combination switch, you may fi nd either circuit A or B:
A. Single-circuit wiring (see Fig. 2): Three wires are attached to the combination
switch. The HOT feed wire
bringing power into the box is
connected to the side of the
switch that has a connecting tab.
The wires carrying power out to
the loads are connected to the
side of the switch that does not
have a connecting tab. A neutral
wire should be present in the
wall box. A ground wire may
also be present and connected
to a ground terminal on the old
switch.

3. Prepare the Wires.
Tag the wires connected to the existing switch, so that
they can be identifi ed later. Disconnect the wires. Make
sure the insulation is stripped off the wires to expose
their copper cores to the length indicated by the “Strip
Gage” in Fig. 5 (approx. 1/2 inch).
4. Wire the sensor.*
Twist the existing wires together with the wire leads on the RS-350-N sensor
as indicated below. Cap them securely using the wire nuts provided (See Fig 6).

B. Separate-circuit wiring (see
Fig. 3): Four black wires are
attached to the combination
switch. HOT feed wires from
the power source are attached
to the side of switch that has
a connecting tab, and the
connecting tab is removed.
Wires carrying power from the
switch to loads are connected to
the side of the switch that does
not have a connecting tab. A
neutral wire should be present
in the wall box. A ground
wire may also be present and
connected to a ground terminal
on the old switch.
If you are substituting two single
pole switches, each single pole
circuit should match the following
description:
In a Single Pole Circuit (see Fig.
4), two single wires connect
to two screws on the existing
switch. A ground wire may also
be present and connected to
a ground terminal on the old
switch. A neutral wire should
also be present in the wall box.

CAUTION - FOR YOUR SAFETY: Connecting a proper ground to the
sensor provides protection against electrical shock in the event of
certain fault conditions. If a proper ground is not available, consult
with a qualifi ed electrician before continuing installation.
Only connect the RS-350-N to one of the three circuit options described. The
RS-350-N is not suitable for 3-way switching. If the existing wiring does not
match any of the previously described circuit options, you should consult with a
qualifi ed electrician.
* These instructions assume wiring the RS-350-N to two independent feed
wires (HOTs). If you only have one HOT feed wire coming into the wiring box,
connect it to both the solid Brown and solid Black wires on the RS-350-N.

SENSOR ADJUSTMENT &
PROGRAMMING
To program the RS-350-N, you use
controls located under the ON/OFF
buttons. The wall switch cover plate
must be removed to gain access to the
mode button and adjustment trimpots
under the ON/OFF buttons.
1. Firmly grasp the side edges of the
Lock Bar and gently pull it away from
the switch face until it clicks. Do NOT
attempt to pull the Lock Bar off of the
switch!
2. Firmly grasp the outside edges of the
ON/OFF buttons. Slide the buttons
downward approximately 1/2 inch
to expose the mode button and
adjustment trimpots.
Setting up the Operating Mode
Select the operating mode for each
relay by pressing the Mode button. The
amber LED behind each of the switch
buttons blinks to indicate the selected
mode for that particular associated relay:
• One blink indicates Mode 1 (Vacancy Sensor Operation), Manual-ON/OFF,
Auto-OFF
• Two blinks indicate Mode 2 (Occupancy Sensor Operation), Auto-ON/OFF
w/manual control and reset to auto (after 5 minutes of vacancy)
To change the mode, press the Mode button once to set the unit to mode 1
or press the Mode button twice to set the unit to mode 2. The LED blinks to
indicate the selected mode. It repeats the selected mode three times. After
that, the unit operates in the indicated mode.

Adjusting the Time Delay
Turn the right trimpot counter-clockwise to reduce the amount of time both loads
will remain on after the last motion detection (minimum = 15 seconds). Turn the
same trimpot clockwise to increase this time delay (maximum = 30 minutes).
Warning: Do not overturn the time delay adjustment trimpot!
Adjusting the Light Level (Feature applicable to relay #1 only)
This feature, applicable only to relay # 1, is factory set at maximum, so that even
the brightest light will not prevent the sensor from turning the load, connected
to the relay # 1, ON when it detects occupancy. If this feature is not needed, leave
the light level at maximum, fully clockwise.
1. The light level must be adjusted when lights would normally be turned OFF
because there is enough natural illumination.
2. Set the sensor to Mode 2 and reduce the time delay to 15 seconds.
3. Adjust the light level to minimum. Let the sensor time out so lights connected
to the relay #1 are OFF and then wait 30 seconds more.
4. Without casting a shadow on the sensor, enter the area. The lights connected
to the relay #1 should remain OFF.
5. Adjust the light level trimpot clockwise in small increments. Wait 5-10 seconds
after each adjustment to see if the lights connected to relay #1 turn ON.
Continue this procedure until the lights connected to relay #1 turn ON. At this
setting the lights connected to relay #1 will not turn ON automatically with
occupancy if the light level is above the current natural illumination.
6. Reset the time delay to the desired setting.
Warning: Do not overturn the light level adjustment trimpot!
TEST MODE
During the TEST mode, the controlled loads turns ON for 5 seconds each time the
sensor detects occupancy.
To test the detection coverage:
1. Press and hold any of the ON/OFF buttons. After 10 seconds the nightlight
fl ashes. The loads turn ON if they were not already ON. The sensor is now
in a TEST mode that lasts 5 minutes. (You can end the TEST mode sooner by
pressing the same ON/OFF button for another 10 seconds).
2. Move out of the coverage area or stand very still. The controlled loads turn OFF
after 5 seconds if no motion is detected.
3. Move into the coverage area. The controlled loads turn ON for 5 seconds
each time the sensor detects motion. After 5 seconds expire without motion
detection, the loads turn OFF. The controlled loads turn ON automatically with
the next motion detection and stay on for 5 seconds.
4. Repeat as necessary to ensure that the desired coverage areas are within
detection range.

TROUBLESHOOTING
Lighted switches are OFF, no load response when pressing any of the
ON/OFF buttons:
• Make certain that the circuit breaker is on and functioning.
Lighted switches are ON, no load response when pressing any of the
ON/OFF buttons:
• Check the loads connected to the sensor (i.e. light bulbs
and/or the motor switch on the fan mechanisms).
Load will not turn ON automatically when the area is occupied and
the corresponding sensor relay is in Mode 2 (the associated lighted
switch is ON):
• If you are troubleshooting the load connected to relay #1, press ON/OFF
button #1. If the load turns ON, check the light level setting and also
make sure the sensor lens is not blocked. The light level can prevent
the sensor’s relay #1 from turning on the load automatically.
• If none of the loads connected to relay #1 or relay #2 turn ON when you
press the associated ON/OFF button, check each of the loads connected to
the sensor (i.e., light bulbs and/or the motor switch on the fan mechanism).
The loads will not turn OFF automatically:
• Press each of the ON/OFF buttons. If the controlled
loads turn OFF, go to next step.
• The time delay can be set from 30 seconds to 30 minutes. The time
delay applies to both sensor relays. Ensure that there is no movement
within the sensor’s view for the set time period. Hot air currents and
heat radiant devices can cause false detection. Make sure the sensor
is at least 6 feet (2 meters) away from devices that are a signifi cant
heat source (e.g., heater, heater vent, high wattage light bulb).
If load does not respond properly after following troubleshooting, turn OFF
power to the circuit then check wire connections or call technical support.
