WSD Series

Wall Switch Sensor

Overview

The WSD LV Series is a low voltage wall switch occupancy sensor that is stylish, easy to install, and simple to use. Ideal for private offices, copy rooms, closets, or any small enclosed space without obstructions, the WSD LV uses the industry’s best Passive Infrared (PIR) technology to achieve excellent small motion detection up to 20 ft. A user programmable time delay ensures that once the room is vacated the sensor will time out and turn off the lights. WSD LV sensors also have additional On Modes and Switch Modes that are all fully programmable using the front push-button. For rooms with obstructions the WSD PDT LV should be considered.

Sensor Operation

The sensor detects changes in the infrared energy given off by occupants as they move within the field-of-view. When occupancy is detected, a self-contained relay switches the connected lighting load on. The sensor is line powered and can switch a range of line voltages. An internal timer, factory set at 10 minutes, keeps the lights on during brief periods of inactivity. This timer is push-button programmable from 30 seconds to 20 minutes, and is reset every time occupancy is re-detected. This state-of-the-art design requires no field calibration or sensitivity adjustments.
