Catalog Number: RSEN-W12
Total Lighting Control
Line-voltage Wall Switch Occupancy Sensor
DESCRIPTION AND OPERATION
The RSEN-W12 is a self-contained motion-sensing
lighting control which replaces a conventional wall
switch for energy savings and convenience. Lights turn
off automatically after a room is vacated.
Built-in sensors produce low intensity, inaudible sound and
detect changes in sound waves caused by motion, such as
walking into the room, reaching for a telephone, turning in a
chair. The sensor does not respond to audible sound.
In the Automatic ON mode, the lights turn on automatically
when a person enters the room. In the Manual ON mode,
lights are turned on by pressing the touchplate on the switch.
Modes can be changed by flipping the concealed switch under
the touchplate. In either mode, lights will remain on as long
as motion is detected in the room. When no motion is detected,
the lights will turn off automatically after the pre-set time
delay. Following this, a “grace period” of approximately ten
seconds allows lights to be turned on again by motion.
At any time, lights may be turned off while the room is
occupied by pressing the touchplate. The RSEN-W12 is fully
self-resetting; lights turned off manually in Automatic ON
mode will stay off while the room remains occupied. After the
room is vacated and the preset time delay and grace period
have elapsed, the lights will remain off until turned on
automatically the next time someone enters the room.
The RSEN-W12 can be used with a standard toggle switch to
split the lighting load for rooms that are wired for two
switches as shown in the wiring diagram.

INSTALLATION
Coverage
The RSEN-W12 is designed for offices or small rooms up to
300 square feet. Although total coverage of minor motion is
450 square feet, wall switches are normally mounted off-center
in a room which reduces the coverage attainable.
Basic Installation Steps
1. Turn off power at the circuit breaker.
2. Wire and mount the switch in standard junction box.
3. Restore power to the circuit.
4. Adjust settings and test.
Location
When installing the RSEN-W12 in a new junction box, choose
the switch location carefully to provide optimum coverage of
the occupied area. When replacing an existing wall switch,
bear in mind that there must be a clear line of sight between
the sensor and the area to be covered. Avoid pointing the
switch directly into the hallway where it may detect passers-by.
Mounting
CAUTION: Before installing or performing any service
on an RSEN-W12, power must be turned off at the
circuit breaker panel.

The RSEN-W12 can replace one switch in any standard single
or double gang box. It may be installed in the same manner as
an ordinary wall switch. Wire the RSEN-W12 as described in
the wiring section.

Wiring
CAUTION: The RSEN-W12 is designed for use with
either 120 VAC or 277 VAC only. Do not use with any
other voltage. Do not wire to control receptacle circuits.
Verify that the connected load does not exceed the RSEN-W12
ratings. Use twist-on wire connectors for all connections. All
installations should be in compliance with the NEC and all
state and local electrical codes. The RSEN-W12 can be wired
to control both an exhaust fan and lighting provided the total
load does not exceed the maximum load rating (in Amps) for
the automatic wall switch.
10' x 15' OFFICE
One Circuit – One Lighting Load: Connect one wire to the
switchleg for the load. Connect the other wire to the hot lead.
Connections are not polarity sensitive.
One Circuit – Two Lighting Loads: The combination of
Load 1 and Load 2 must not exceed the maximum load rating.
Consult with the building manager and occupant to determine
which lights should be off (Load 2) when the toggle switch
adjacent to the RSEN-W12 is open (OFF).
Caution: If a room is wired for two circuits using two
separate hot leads, it is very important to connect only
one circuit to the RSEN-W12. Split one circuit into two
switchlegs and cap the unused hot lead inside the box.
The RSEN-W12 must always control Load 1, while its control
of Load 2 is selected manually by opening and closing the
toggle switch. Connect one wire to the switchleg for Load 1
and one side of the toggle switch for Load 2. Finally, connect
the other wire from the RSEN-W12 to the hot lead. Connections are not polarity sensitive.
