4. Instal·lació
Before beginning installation, ensure power is disconnected at the circuit breaker.
4.1 Instruccions de cablejat
The DSW-100-W sensor requires connection to Line (L), Load, and Ground wires. It is compatible with 120VAC and 277VAC systems.
- Line (Black Wire): Connect to the incoming hot wire from the electrical panel.
- Load (Red Wire): Connect to the lighting fixture or load.
- Ground (Green Wire): Connect to the electrical system ground.
- Neutral (White Wire): This sensor typically does not require a neutral connection for basic operation, but always refer to the specific wiring diagram on the device or included instructions.

4.2 Muntatge
Install the sensor into a standard electrical wall box. Ensure the sensor is securely fastened and the faceplate is properly attached after wiring is complete.
5. Instruccions de funcionament
The DSW-100-W offers flexible operation modes and settings.
5.1 Modes de funcionament
- Mode d'encesa automàtica: Lights turn on automatically when occupancy is detected and turn off after a preset time delay when the space becomes vacant.
- Manual-On Mode: Users must manually turn on the lights using the switch. The sensor will then automatically turn off the lights after a preset time delay when the space becomes vacant. This mode is ideal for energy code compliance where manual-on is required.
5.2 Time Delay and Sensitivity Adjustment
The sensor typically includes adjustable settings for time delay (how long lights remain on after vacancy) and sensitivity for both PIR and Ultrasonic detection. Refer to the specific labels on the device (e.g., "1.0 Time", "Ultrasonic") for adjustment points. Use a small screwdriver or similar tool to carefully adjust these settings as needed for your application.
5.3 Audible Alert
The DSW-100-W features a selectable audible alert that provides a warning before the lights turn off due to vacancy. This can be enabled or disabled based on user preference.
6. Manteniment
The DSW-100-W sensor requires minimal maintenance.
- Neteja: Periodically wipe the sensor lens and housing with a soft, damp tela. No utilitzeu netejadors abrasius ni dissolvents.
- Obstruccions: Ensure the sensor's detection area is free from obstructions such as furniture, tall plants, or partitions that could block its view or ultrasonic waves.
