DESCRIPTION AND OPERATION

The RS-250 Universal Application Wall Switch Vacancy Sensor is designed to
replace a standard light or fan 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 controls are desirable.

Like a standard switch, you press the ON/OFF button to turn the light or fan
(controlled load) ON and OFF. Unlike a standard switch, the RS-250 automatically
turns OFF the controlled load after the coverage area has been vacant for a period
of time (Time Delay). If motion is detected within 30 seconds after it automatically
turns OFF, the RS-250 automatically turns the load 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 load
ON automatically upon detection of occupancy in the area.

Lighted Switch

To help you locate the RS-250 in a dark room, the amber LED illuminates the
ON/OFF button while the controlled load is OFF. When the controlled load is ON,
the LED is OFF.

Operating Modes

There are two operating modes to select from 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-250 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-250 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.

Call 888.817.0571 for Technical Support

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. For additional information on how to adjust
it, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this
installation manual.

Light Level

When the sensor is set for occupancy sensor Mode
2 (Auto-ON/OFF) the light level feature prevents
the sensor from automatically turning the lights
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-250 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 light to turn OFF even though
someone is in the area.

Windows, glass doors, and other transparent barriers will obstruct

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-250, replacing lamps, or doing any electrical work.

HOT (power from

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 old switch out from the
wall box.

Ground

2. Identify the type of circuit.

In a Single Pole Circuit (see Fig. 2), two single

wires connect to two screws on the existing
switch. A ground wire may also be present and

Fig. 2: Typical Single

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-250 to a Single Pole Circuit. The RS-250 is not suitable

for 3-way switching. If the existing wiring does not match the description for a
Single Pole Circuit, you should consult with a qualifi ed electrician.

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. 3) (approx.
1/2 inch).

6. Restore power to the circuit.

Turn ON the breaker or replace the fuse.

7. Test the sensor’s operation.

See TEST MODE.

8. Review SENSOR ADJUSTMENT &

PROGRAMMING below.

Initial Power-up Delay

There is an initial warm-up
period the fi rst time power is
applied to the unit and after
a power failure lasting more
than 5 minutes. If the sensor
is in Mode 2, (automatic-ON) it
may take up to 1 minute before
the lights turn ON. However,
the lights can be turned
ON/OFF manually by pressing
the ON/OFF button at any time
when power is supplied to
the unit.

If you want to make adjustments, follow the

instructions in SENSOR ADJUSTMENT & PROGRAMMING, below.

9. Attach the new cover plate.

Secure it to the wall box with the screws provided.

SENSOR ADJUSTMENT &
PROGRAMMING

To program the RS-250, you use controls
located under the ON/OFF button. The wall
switch cover plate must be removed to gain
access to the mode button and adjustment
trimpots under the ON/OFF button.

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 side edges of the ON/
OFF button. Slide the button downward
approximately 1/2 inch to expose the
mode button and adjustment trimpots.

Setting up the Operating Mode

Select the operating mode by pressing the

Fig. 5: Sensor Adjustment Controls

Mode button. The amber LED behind the
switch button blinks to indicate the selected
mode:

• 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. 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 the load
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!
