MRD‑5xx Series
SmartDALI Occupancy Sensor
The MRD type of the TRANS‑PIR sensor family are two‑way IR remote programmable DALI occupancy sensor featuring bi-level StepDIM or continuous SmartDIM control to lighting with DALI driver or ballast. The sensor can be powered by either line voltage or DALI bus to provide multi-scheme occupancy sensing control through DALI Broadcast commands.
All TRANS‑PIR sensors are available with various mounting options and interchangeable lenses.
