Description
HDL Occupancy Plus Buspro presence detector, model MSMW24-BP.21. Unlike simple PIR motion sensors, this detector uses 24 GHz millimetre-wave radar to detect people including subtle motion, making it suitable for occupancy-aware lighting and room automation.
Detection and room automation
- Human presence and micro-motion detection at 24–24.25 GHz
- Built-in illuminance sensor, range 0–1200 lux
- Temperature sensing range: −20 to +60 °C
- Two dry-contact inputs for external signals
- Detection area: up to 6 m detection diameter at 3 m mounting height, depending on mounting height and surroundings
- Buspro system logic, adjustable sensitivity and grouping of multiple sensors
Electrical and installation
- Network: HDL Buspro
- Supply: 12–30 V DC; rated consumption 50 mA maximum at 24 V DC
- Manufacturer mounting dimension options: Ø66 × 34.6 mm and Ø48.5 × 27.5 mm, depending on fitting arrangement; confirm the matching cut-out and housing
- Recommended height: 2.5–3.5 m
- Indoor ambient: −5 to +45 °C; IP20 protection
Selection and commissioning
Confirm the correct Buspro bus, application software, installation direction and coverage. Radar signals may respond to motion through some materials, so tune sensitivity carefully in partitioned spaces. These sensors are for building automation, not certified intrusion or life-safety alarms.
