SWX-200-B Series Battery Powered Wireless Ceiling Mount Occupancy Sensors

Overview

The SENSORWORX^®wireless ceiling mount occupancy sensor is a simple, yet reliable battery powered control solution. Preferred by contractors for their flexible mounting methods, SENSORWORX wireless sensors greatly reduce total installation time and wireless pairing fuss. Requiring just a few seconds per device, SENSORWORX wireless sensors can be linked to one or more wireless load controllers (such as the SWX-851 wireless wall switch, or a SWX-950 series wireless power pack). Additionally, these sensors can be configured to work in applications with other wireless or wired ceiling, corner, or hallway sensors to provide extended coverage in large or irregularly shaped spaces.

As with all SENSORWORX products, the latest PIR (passive infrared) technology and techniques are used to provide unmatched occupant detection performance and energy savings. Additionally, units are available with an integrated microphone to provide overlapping passive acoustic detection for rooms with obstructions or where occupant motion is limited. An integrated daylight harvesting photocell is also an available option for PIR only units.

Basic Operations

Sensors detect movement in the infrared energy that radiates from occupants as they move within the device’s field-of-view. Once occupancy is detected, the sensor immediately signals a wirelessly linked load controller (e.g. power pack) to switch on or dim up the connected lighting. If equipped with passive dual technology (PIR/Acoustic), the units microphone is then also enabled to further enhance detection while the lights are on. At regular intervals, the sensor will retransmit its latest occupancy status such that the load controller can keep lights on for occupants during brief periods of inactivity, while returning the space to an energy saving lights off (or dim) state once no longer occupied.
