3-Way Motion

Sensing Switch

The 3-Way Motion Sensing Switch (MSS) detects motion to turn on
lights for an adjustable amount of time. A built-in photo cell can be set
to keep lights off when the lights aren't needed. The unit has excellent
sensitivity and a wide 150

0

detection range. It can be used with incan-

descent lighting as well as rapid start fluorescent lighting.

The MSS can be used to replace either a 3-way wall switch or a
single pole switch. Some codes require installation by a qualified elec-
trician.

Features include:
• 150

0

motion detection angle

• Adjustable on-time from 5 sec. to 20 min.
• Adjustable photocell
• Works with incandescent and rapid start fluorescent lighting
• Works with motors up to 1/8 hp.
• Slide switch selectable OFF, ON AND AUTO modes.

WARNING: Turn power off at the circuit breaker before wiring.

Note: a "3-way" circuit controls lights from two sepa-
rate switches. If you want to use this product in a sin-
gle switch circuit or if you want to install more than one
motion sensing wall switch, see page 6
• Remove the decorative coverplate (secured by two

screws).

• Remove Control Cover. (Press in with screwdriver.

Swing out cover to remove.)

• Choose which switch will be replaced and remove it.
• For easier re-wiring later, mark the house wiring with

tape indicating where the wire had been connected.

• Connect the 3-Way Motion Sensing Switch as shown in the diagram below:

• Mount the MSS into the junction box with the two junction box screws.
• Turn the circuit breaker back on.
• Preset the controls: Time to min. (fully CCW), Photo Adjustment fully clockwise. Cover the lens with masking

tape.

• With the motion sensor in the "ON" position, turn the remote switch on and off several times. Go to step 1, 2,

or 3, depending on results.

WARNING: Shut off all power at fuse box or circuit breaker before beginning installation.

If you have a problem with your Wall Switch, first follow this guide. If the problem persists, call the
customer service hotline at 1-800-435-4448 between 8:00 AM and 6:30 PM ET weekdays.

Replace control panel cover and install the decorative wall plate. In installations where the GE motion sensor
switch is combined with other switches or outlets on an expanded box, a combination wall plate will need to
be purchased. Various combination wall plates are available at Home Centers and Electrical Supply Stores.

Slide the switch a couple of times to make sure it operates freely.

When the light in the room is at the
level you want the lights to turn on,
set the switch to the AUTO position.
Put the TIME control to the 5 sec-
ond position.
Put the LIGHT control to the mini-
mum dark (fully counter-clockwise)
position.
Wait for the lights to turn off.
Turn the LIGHT adjustment clock-
wise in very small steps and wait 2
seconds before moving your hand
in front of the sensor. Repeat until
the lights controlled by the sensor
come on. The light will now come
on when the light level is at or below
the present level and motion is
detected.

To adjust the photocell:

MODE Selection Switch

Moving the switch selects one of three modes of operation: OFF, AUTO, ON

OFF: Lights stay off.

AUTO: Lights come on for time set when motion is detected and the light level is below the set level or when
3-way switch is manually switched.

ON: Lights stay on continuously. Flipping 3-way switch has no effect.

The sensor can be prevented from turning on lights
when there is already enough light in the room. Use a
small phillips screw driver to set the light level using this

diagram as a guide. In the fully clock-

wise position, the sensor turns on
lights even in full daylight. In the fully
counter-clockwise position, the sen-
sor only turns on lights when the sur-
rounding light level is very low.

SYMPTOM

Light does not come

mode.

Lights do not stay
on in the Auto mode.

POSSIBLE CAUSE

Circuit breaker or fuse is
turned off.
If the lamp being controlled
has another switch, it may
be turned off.
Bulb is defective.
LIGHT control is set too far
toward the DARK position.
MODE switch is set to OFF
instead of AUTO.
Poor connection.

Motion has stopped in the
room.
TIME control is set for too

Light comes on for
no reason in the Auto
mode.

POSSIBLE CAUSE

Incorrect wiring.
MODE switch is set to
ON instead of AUTO.
Motion is still present.
Delay set by TIME
control has not
expired.
Heating or cooling ob-
jects (such as air
vents, appliances, or
drafts through the wall
box) are causing false
triggering.
Switch on the sensor
has been turned off
and back on.
There was a momen-
tary power interrup-
tion. The light will turn
off automatically when
the "on" time expires.

GENERAL APPLICATION INFORMATION

The detector is more sensitive to motion across the front of the sensor than to motion towards the sensor.

The detector senses heat in motion and possible heat sources that change temperature quickly. Therefore, to
avoid false triggering, avoid placing the sensor where it will be aimed at air conditioners, heaters, and other
sources of heat or cold.

NEW APPLICATION

Choose a location where the motion sensor has a clear view of
the entire area where occupant motion may occur.

RETROFIT APPLICATION

Motion sensing switch will replace existing wall switch. Use only
where the existing switch location provides a clear view of the
occupied area.

Included are: • The sensor switch • Cover plate • 4 wire connectors • 2 large screws • 2 small screws.
