Redwood Sensor - Model 3M1
Installation Instructions
Model No:
SEN-3M1-W
The Redwood Sensor controls and dims a connected Redwood Ready third-party LED fixture, collects data on light levels, temperature and motion, and transmits this environmental data back to the Redwood Engine. The Engine powers
the Sensor via low voltage cable.
The Redwood Sensor is easily installed in the ceiling tile or junction box near the
fixture and accepts standard category 5e, 6 or 6a cable via RJ45 connectors for
fixture and data connections. In addition, the Sensor can also connect to an
electrical light switch with 18AWG via snap-in connectors to enable manual lighting control.
Redwood Sensor - Model 3M1 requires Redwood Engine 3 - Model 4834 running
3.1 software.

º Range: 32°F to 212°F (0°C to 100°C)
• Passive Infrared (PIR) sensor for
motion detection
Preparation
•For a lay-in fixture (2x2, 2x4 or 600x600), sensors need to be placed in the ceiling tile adjacent to the fixture. For downlights, sensors can be placed in the same ceiling tile. Fixtures
come with attached RJ45 plugs and wires. This wire will limit the distance of the sensor from
the fixture.
• Sensors should be placed close to the fixture, preferably within 2 inches (50.8mm) in order to obtain
accurate light level readings and enact daylight
harvesting accurately. Determine where in the ceiling tile the Redwood Sensor needs to be installed;
refer to the diagram on the next page.

• Be sure the Sensor is clear of any other equipment above the tile.
• The plastic Sensor cap should be tight against the ceiling tile.
• The Sensor may be rotated inside the ceiling tile’s hole, but it must remain perpendicular to the tile.
• Redwood recommends that you do no place sensors near heating vents, AC units or any other electrically dynamic
system.
• Sensors should be placed in areas with minimal air movement to ensure proper operation of the DPIR motion sensor.
• The Redwood Sensors have been tested by UL to UL2043 which ensure slow smoke-emitting characteristics and
suitable fire resistance for equipment that may be installed in environmental air-handling spaces, as described in Article
300.22(c) of the NEC (2008).
• When the product is installed in air-handling spaces, such as above some suspended ceilings, the cabling employed
should be suitable under NEC (2008) Article 800.154 and marked accordingly for use in plenums and air-handling
spaces with regard to smoke propagation, such as CMP. The products and wiring should be installed in accordance
with all applicable local regulations and practices.
Installation Instructions
Step 1: Within 2" (50mm) of the fixture, drill a 1" (25.4mm)
diameter hole in the ceiling tile.
Step 2: Carefully push the Sensor through the ceiling tile.
Step 3: Twist and lock the adjusting height Sensor ring to
tighten the Sensor against the tile.
Step 4: Connect fixture to the Sensor 3 white RJ45 jack.
Step 5: Connect the Sensor 3 black RJ45 jack back to the
Redwood Engine using category cable.

Redwood Sensor 3 Installation Instructions
Connecting an Electrical Light Switch
The Redwood Sensor can be connected to a single pole, single throw (SPST) electrical light switch using 18AWG wire.
(This does not apply to connecting the Redwood Dimmer or Scene Control Wall Switch). When connected to an individual sensor in a designated room, the electrical light switch will control all of the fixtures in that room manually.
Preparation
•Determine location for the wall switch and
associate Sensor.
• Lay low-voltage two 18AWG cables from the
Sensor to the wall switch location. Using
18/2 jacketed solid core bell wire is recommended for this application.
• Strip the end of the 18AWG cables by 1/4”
(0.6cm).
• Cut or use an existing standard-sized wallplate opening for a NEMA standard, OTS
electrical switch box with an open back.
Installation Instructions
Step 1: Make sure the light switch is in the “ON” position.
Step 2: Run 18AWG wire from the light switch through the
light switch electrical box.
Step 3: Connect one end of the wire to Port C on Sensor 3.
Step 4: Connect the remaining end to either Port A or Port
B.
Step 5: Place the switch faceplate on top of the light
switch in the electrical switch box and tighten the
screws.
