Each Wattstopper BZ series power pack can supply power for 5 UT-300

sensors. When using more sensors than this, multiple power packs are

required.

Refer to the wiring diagram 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 LVS-1 Momentary Toggle Switch, or

RS2-3 Low Voltage Momentary Switch to the above applications–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.

• 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.

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.
