WATTSTOPPER DSW-301-347-I DUAL TECHNOLOGY WALL SWITCH OCCUPANCY SENSOR 347V IVORY

WATTSTOPPER DSW-301-347-I Dual Technology Wall Switch Occupancy Sensor 347V Ivory The WATTSTOPPER DSW-301-347-I is a dual technology occupancy sensor designed for wall switch replacement applications, combining passive infrared (PIR) and ultrasonic sensing technologies. This sensor is engineered for precise occupancy detection to control lighting loads up to 1500W ballast or LED at 347 VAC. Ideal for retrofit projects in commercial spaces such as offices, conference rooms, classrooms, and break rooms, it supports multi-way control from up to four locations, making it suitable for complex lighting control needs. The sensor also complies with 2017 NEC requirements and is available through electrical distributors and switchgear suppliers as part of advanced lighting solutions and wire and cable integration.
