It also features adjustable time delay (15 seconds to 30 minutes) and adjustable sensitivity, plus multi-location wiring for multi-way applications. Designed for indoor spaces such as bathrooms, storage rooms, utility rooms, L-shaped rooms, hallways, offices, and healthcare or educational facilities, it complies with California Title 24 energy standards and NEC requirements and is finished in Almond (A).
