WIRING DIRECTIONS

WARNING
TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE
INSTALLING POWER PACKS, SWITCHES OR SENSORS.
Each WattStopper BZ series power pack can supply power for 5 DT-305 sensors. When
using more sensors than this, multiple power packs are required.
Refer to the wiring diagram on the next page for the following procedures:
Connect the low voltage:
• RED wire (+24VDC) from power pack to the +24V terminal on the sensor.
• BLACK wire (Return) from power pack to Common terminal on the sensor.
• BLUE wire from power pack to Control Out terminal on sensor.
To add a MANUAL SWITCH such as the LVSW Momentary Toggle Switch, or RS2-3 Low
Voltage Momentary Switch to the above applications (see wiring diagram "Manual-On
wiring with low voltage momentary switch") – connect:
• Wire from one side of switch to +24V terminal on sensor.
• Wire from other side of switch to Man Switch terminal on sensor.
Wiring the ISOLATED RELAY: The Isolated Relay is rated for 1A@30VAC/VDC. Connect the wires necessary to the application that requires
this output:
• Relay Common (must be used for proper operation)
• N.O. (Normally Open)–Closed when occupancy is detected
• N.C. (Normally Closed)–Open when occupancy is detected

CONNECTING WIRES

• Care should be taken to separate high voltage power from low voltage (Class 2) control wiring.
• All connections to sensor are low voltage, Class 2.

MOUNTING THE SENSOR

Directly to Ceiling
1. Attach the plastic spring clips to the edge of the sensor in the slots provided.
2. Cut a 3.5" to 4" round hole in the acoustic ceiling tile at the mounting location. A 3.5" hole is
recommended for a secure fit.
3. Pull the low voltage wire from the power pack to the sensor through the hole.
4. Connect the low voltage wires to the appropriate terminals on the sensor.
5. Push the sensor up through the hole until the Spring Clips hold the sensor securely in place.
6. Snap the front cover onto the sensor.
Using an Octagonal J-Box
1. Pull the low voltage wires from the power pack into the J-Box through the conduit knockout.
2. Connect the low voltage wires to the appropriate terminals on the sensor.
3. Loosen the appliance mounting screws attached to the J-Box
4. Align the sensor in the J-Box so that the mounting screws on the box match the key holes
on the sensor's rear housing.
5. Push the sensor up into the J -Box and twist it so that the mounting screws are seated in the
keyhole slots.
6. Tighten the two screws to secure the sensor to the J-Box.
7. Snap the front cover onto the sensor.
