Watt Stopper DT-300 Dual Technology Ceiling Occupancy Sensor Instruction Manual

1. Introducció

1.1 Producte acabatview

The Watt Stopper DT-300 is a dual technology ceiling occupancy sensor designed to automatically control lighting based on occupancy detection. It integrates both Passive Infrared (PIR) and Ultrasonic technologies to provide comprehensive coverage and reliable performance. This sensor is suitable for various commercial and institutional applications, ensuring energy savings by turning lights off when spaces are unoccupied.

2.3 Instruccions de muntatge

1. Seleccioneu la ubicació: Choose a central ceiling location within the desired coverage area (up to 1000 sq ft). Avoid placing near HVAC vents or direct sunlight, which can affect sensor performance.
2. Preparació de l'obertura: Create an appropriate opening in the ceiling for the sensor and power pack.
3. Connecteu el cablejat: Follow the wiring diagram (Figure 4) to connect the sensor to the power pack and the power pack to the building's electrical system and lighting load.
4. Muntatge del sensor: Secure the DT-300 sensor into the ceiling opening.
5. Mount Power Pack: Secure the power pack in an accessible location, typically above the ceiling or in a junction box.
6. Restaura l'alimentació: Un cop totes les connexions estiguin segures i verificades, restableu l'alimentació del circuit.

3. Funcionament

3.1 Dual Technology Detection

The DT-300 sensor utilizes both PIR and Ultrasonic technologies. Lighting will turn on when tots dos technologies detect occupancy. Once the lights are on, detection by tampoc technology is sufficient to keep the lights on. This dual detection method helps minimize false triggers and ensures reliable occupancy sensing.

3.2 Manual-On Operation

The sensor supports manual-on operation via a low voltage switch. If a switch is connected, users can manually turn on the lights. The sensor will then maintain the lights based on occupancy detection, turning them off after the set time delay when no occupancy is detected.

3.3 Time Delay and Walk-Through Mode

The sensor features an adjustable time delay, which determines how long the lights remain on after the last detected occupancy. The Walk-Through Mode is an energy-saving feature that reduces the time delay if a person quickly enters and exits the space, preventing the lights from staying on unnecessarily.

4. Manteniment

4.1 Neteja

To ensure optimal performance, periodically clean the sensor lens and housing with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the sensor's components.

4.2 Sensor Checks

Regularly verify the sensor's detection capabilities by walking through the coverage area. If the sensor is not responding as expected, refer to the troubleshooting section. No specific calibration is typically required for this model under normal operating conditions.
