BDS‑7xx Series

Low Voltage Dual‑Tech Wall Switch Sensor

The BDS type of the WALLSENZR family are dual technology low voltage wall switch sensors designed to provide isolated dry contact output for load switching via the connected PPU or BMS. Sensor setting and control mode can be configured by Accu‑Set pot and DIP switch behind the button cover. This wall switch combines digital Passive Infrared (PIR) and High Frequency Doppler (HFD) sensing technologies into an aesthetically pleasing housing to provide second-to-none occupancy/vacancy sensing based lighting control for all applications.

Occupancy‑Vacancy sensor changeable control
Dual‑tech or single HFD sensing mode switchable
Front accessible sensor operation configurations
No grid opening - aesthetics pleasing sensor front
4 levels of HFD sensitivity setting programmable
180° field of view with coverage exceeds 100 sq. m.
Specialized lens provides vandalism protection
Accu‑Set digital potentiometer sensor settings
Dry contact relay output for versatile control
Screwless wall plate offers high end appearance
Low cut back cover provides more wiring space
