DESCRIPTION AND OPERATION
The RWU600B Vacancy Sensor is designed to replace a standard light or fan
switch. It is ideal for bedroom and bathroom applications.
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 RWU600B
automatically turns OFF the controlled load after the coverage area has
been vacant for 30 minutes. If motion is detected within 30 seconds after it
automatically turns OFF, the RWU600B automatically turns the load back ON.
Pilot Light
To help you locate the RWU600B in a dark room, the pilot light illuminates the
ON/OFF button while the controlled load is OFF. When the load is ON the pilot
light is OFF.
Coverage Area
The RWU600B has a maximum coverage range of 180 degrees and a coverage
area of 600 square feet (56 square 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 the sensor’s view
and prevent detection.

WARNING
Disconnect power to the wall switch box by turning OFF the circuit
breaker or removing the fuse for the circuit before installing the
RWU600B, replacing lamps, or doing any electrical work.
INSTALLATION & WIRING
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.
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 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 qualified electrician before
continuing installation.
Only connect the RWU600B to a Single Pole Circuit. The RWU600B 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 qualified
electrician. If 3-way switching is required, use P&S 3-way occupancy sensor,
RW3U600.
3. Prepare the wires.
Tag the wires currently connected to the existing switch,
so that they can be identified 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 (approximately 1/2 inch).

4. Wire the sensor.
Twist the existing
wires together with
the wire leads on the
RWU600B sensor as
indicated below. Cap
them securely using
the wire nuts provided.
See Fig 4.
• Connect the green or
non-insulated (copper)
GROUND wire from the
circuit to the ground
terminal on the
RWU600B.
• Connect the NEUTRAL
wire from the circuit
and from the lamp or
fan (LOAD) to the white
wire on the RWU600B.
• Connect the power wire
from the circuit (HOT)
to the black wire on the
RWU600B.
• Connect the wire to the
lamp or fan (LOAD) to the red wire on the RWU600B.
5. Put the RWU600B in the wall box with the lens positioned above
the ON/OFF button (lens at top, button at bottom).
Secure it to the wall box with the screws provided.
6. Attach the new cover plate.
7. Restore power to the circuit.
Turn on the breaker or replace the fuse.
