The optional neutral sensors are designed to let installers decide whether they need a neutral sensor after purchasing a wall-switch product. The sensors work with two- or three-wire applications and are compatible with 2011 National Electric Code requirements and with existing wiring. Single and dual relay sensors are available in 120/277 Volt (V) and 347 V models that use passive infrared technology.
