Setup and Installation
Important Safety Information: Before beginning installation, ensure power is turned OFF at the circuit breaker or fuse box to avoid electrical shock. Installation should be performed by a qualified electrician or a knowledgeable individual familiar with electrical wiring.
- Power Disconnection: Locate the circuit breaker or fuse that supplies power to the switch box where the sensor will be installed. Turn OFF the power. Verify power is off using a voltage tester.
- Remove Existing Switch: Carefully remove the existing wall plate and switch from the electrical box. Disconnect the wires from the old switch, noting their connections (e.g., line, load, ground, neutral if present).
- Wiring the Sensor: Connect the wires from the wall box to the corresponding wires on the IOS-DPBIF-IV sensor. Refer to the wiring diagram provided with the product packaging for specific connections. Typically, this involves connecting the Line (hot), Load, and Ground wires. A neutral wire connection may also be required depending on the specific model and electrical code.
- Mounting the Sensor: Gently push the wired sensor into the electrical box. Secure it with the provided mounting screws.
- Install Wall Plate: Attach the decorator wall plate over the sensor.
- Restore Power: Turn the power back ON at the circuit breaker or fuse box.
Note: For detailed wiring diagrams and specific electrical requirements, consult the full installation guide included with your product or available on the manufacturer's website.
Operating Instructions
The Intermatic IOS-DPBIF-IV sensor operates automatically based on detected occupancy. It also includes a manual override button.
Automatic Operation:
- When motion is detected within the sensor's 150-degree field of view, the connected lights will turn ON.
- The lights will remain ON as long as occupancy is detected.
- After no motion is detected for a preset time delay, the lights will automatically turn OFF. The time delay can be adjusted from 15 seconds to 30 minutes. Refer to the product's internal settings or instructions for adjusting this delay.
Manual Override:
The sensor features a manual push-button switch located on the front face. This button allows for manual control of the lights, overriding the automatic occupancy detection.
- Press to Turn ON/OFF: A single press of the button will toggle the lights ON or OFF, regardless of occupancy.
- Return to Automatic: After manual operation, the sensor typically returns to automatic mode after a period of time or upon the next detection of occupancy, depending on the specific model's logic. Consult the full manual for details on how manual override interacts with automatic mode.
Maintenance
The Intermatic IOS-DPBIF-IV Occupancy Sensor requires minimal maintenance to ensure optimal performance.
- Cleaning: Periodically wipe the sensor lens and housing with a soft, dry cloth to remove dust or dirt. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the unit.
- Obstruction Check: Ensure that the sensor's field of view is not obstructed by furniture, curtains, or other objects that could interfere with motion detection.
- No User-Serviceable Parts: The sensor contains no user-serviceable parts. Do not attempt to open or repair the unit. Refer any issues to qualified service personnel.
