The WSD 2p series is a wall switch decorator style passive infrared (pir) sensor designed to control two independent loads. Utilizing two isolated power relays, the WSD 2p is factory set to automatically turn load 1 on when initial occupancy is detected, while holding load 2 off until the push-button is pressed. Although perfect for rooms wired for bi-level lighting, the WSD 2p is also convenient for controlling multiple load types and/or voltages (for example a restroom light and fan).
