Connections
1. Power off the two-wire when installing devices.
2. Install all connections according to the manufacturer’s instructions. Included with the biSensor are two
DRYCONN ® DBG ® Direct Bury connectors with SmartGel ® . You may also substitute DBR/Y connectors.
3. If needed, use polyethylene double-jacketed or UF-B UL PVC double-jacketed two-conductor solid core wire
designed for direct burial systems to connect the biSensor to the two-wire path. The sensor comes with 50ft of
wire.
4. Strip the outer insulation from the two-wire and the biSensor wire (1½”). Strip
the red and black wires on both (½”) and fasten the two red wires together
with the wire nut, then the two black wires with a wire nut, ensuring that
polarity is maintained. Verify communications with the BaseStation before
proceeding.
5. Complete the installation of the waterproof connectors as directed by the
manufacturer’s installation guide by positioning the wires, with the wire nut,
into the gel and firmly snapping the connector.
Burying the biSensor—See other side for biSensor placement information
1. With a flat blade shovel, cut a slit in the grass or soil for the biSensor. Widen the slit with a back and forth
motion.
2. Place the biSensor in the slit horizontally.
 In turf, position the top of the biSensor 2” to 3” deep.
 For other plant material, position the sensor in the top third of the plants’ root zone.
3. With your hands, remove any rocks or gravel touching the biSensor to ensure there are no air pockets. Firmly
repack the soil around the sensor.
4. Bury the biSensor wire deep enough to protect it from digging. Splices to the two-wire
should be placed in a small valve box. Document the location of the biSensor and
biSensor wire positions so they can be avoided when aerating and digging in the area.
5. Using a bucket of water, saturate the soil surrounding the biSensor. Make sure that the soil
around the sensor is firmly compacted. After burial, test the biSensor again from the
BaseStation.
