Product Description
ETC OWS-DT-UW-120/277 Dual-Tech Wall Switch Sensor
Overview
The Dual Tech Wall Switch Sensor (OWS-DT) is a line powered, wall mount, dual technology occupancy sensor with integrated wall switch that communicates wirelessly to Echoflex controllers. The OWS-DTUW-120/277 is a no-neutral conductor powered device connecting to line voltage and earth ground. The OWS-DT-UW-BTY is powered by a long shelf life battery.
The OWS-DT sensor is designed to simplify the control needs for small office spaces, boardrooms or other small enclosed spaces which require a wall switch and occupancy sensor. The integral dimming switch provides occupants with the necessary manual control of their lights.
The OWS fits well in applications where energy codes require the lights to be manually turned ON and automatically OFF with vacancy. The combination of PIR sensor and audio sensing ensures positive occupant detection. Passive microphone technology provides full coverage of audible human activity across the entire PIR detection range. Innovative noise filtering is used to prevent false triggers that keep lights on in empty rooms. When used with Echoflex Solution’s dimming lighting controllers, the switch also provides manual dimming control of the lights. Echoflex controlled receptacles can be automated with the OWS so plug loads operate ON and OFF with the current occupancy state.
The OWS-DT provides 180 lateral degrees of coverage ideal for installation in small offices and boardrooms. Both models are installed in new or existing electrical wall boxes. The OWS-DT-UW-120/277 is connected to 120V or 277V line voltage and earth ground, and does not rely on the neutral conductor being present. The OWS-DT is CEC Title 24 compliant and a key component in Echoflex’s energy saving solutions.
