A Wall Sensor for Private Offices, Closets & Other Small Office Spaces

The WSD from SensorSwitch is a stylish, easy to install, and simple to use Wall Switch Decorator style Passive Infrared (PIR) sensor. It is ideal for private offices, copy rooms, closets, or any small enclosed space without obstructions. A user programmable time delay ensures that once the room is vacated the sensor will time out and turn off the lights.

Additionally, the WSD sensor has several On Modes and Switch Modes that can be programmed using the front push-button. For rooms with obstructions, the Dual Technology WSD PDT Series sensor is recommended. Additionally, all WSD Family sensors have a patent-pending wiring method that enables them to function either with or without a neutral connection. WSD units come pre-configured for wiring without a neutral; however, if connection to neutral is required by code, contractors can convert the unit in seconds (see page 3). All WSD Family sensors utilize 100% digital Passive Infrared (PIR) detection.

Dual Technology (PDT option) versions add Microphonics detection and are recommended for offices and rooms with obstructions. Additional versions include units with dual relays – perfect for bi-level applications, or bathrooms with a light and a fan.

WSD sensors with Passive Dual Technology (PDT option) first see motion using Passive Infrared (PIR) and then engage Microphonics to listen for sounds that also indicate continued occupancy. This patented technology dynamically adapts a sensor to its environment by filtering out constant background noise and detecting only noises typical of human activity.
