Wall Switch Decorator Sensor - Passive Infrared (PIR), 2-Pole


The WSD 2P is an easy to install and simple to use Wall Switch Decorator style occupancy sensor. Utilizing 100% digital PIR detection, the WSD 2P is ideal for private offices, copy rooms, bathrooms, closets, or any small room without obstructions. WSD 2P sensors have two relays, making them perfect for bi-level applications or bathrooms with a light and a fan. All WSD 2P Series sensors have a patent-pending wiring method that enables them to function either with or without a neutral connection. Units come pre-configured for wiring without a neutral; however, if connection to neutral is required by code, contractors can convert a unit in seconds.

SENSOR OPERATION — WSD 2P sensors detect changes in the Passive Infrared (PIR) energy given off by occupants as they move within the field-of-view. Once occupancy is detected the unit will automatically close Pole 1’s relay while still requiring Pole 2’s push-button be pressed in order to close Pole 2’s relay. All modes are user adjustable (see On Modes section).

After the lights are turned on, an internal timer keeps them on during brief periods of inactivity. Once the time delay has expired, lights are turned off automatically. The default time delay is 10 minutes - chosen in order to maximize energy savings while preventing false-offs. This timer is programmable from 30 seconds to 30 minutes, and is reset every time occupancy is re-detected. Patented LampMaximzer technology is also present in these sensors, providing an additional minimum on time (disabled by default) to be utilized if desired.
