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-150U, 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 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.
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-150U to a Single Pole Circuit. The RS-150U 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). A neutral wire should also be
present in the wall box.
4. Wire the sensor.
Twist the existing wires
together with the wire
leads on the RS-150U
Black -> HOT (power
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 green
terminal on the RS-150U.
• Connect the NEUTRAL
wire from the circuit and
from the lamp or fan
(LOAD) to the white wire
on the RS-150U.
• Connect the power wire
from the circuit (HOT) to
Fig. 4: Sensor orientation, wire connections
the black wire on the RS-150U.
• Connect the power wire to the lamp or fan
(LOAD) to the red wire on the RS-150U.
5. Put the RS-150U in the wall box.
Position the lens above the ON/OFF button
(lens at top, button at bottom) and secure it
to the wall box with the screws provided.
6. Attach the new cover plate.
Secure it to the wall box with the screws
provided.
7. Restore power to the circuit.
Turn ON the breaker or replace the fuse.
8. Test the sensor's operation.
See TEST MODE.

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. 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.
