Description
HDL-MSP07M.4CT is a ceiling-mounted multifunction occupancy and environmental sensor for HDL Buspro installations.
Detection and automation
- Passive infrared (PIR) movement sensing, temperature and ambient-light (lux) sensing
- Two dry-contact inputs and configurable universal-switch control logic
- Adjustable detection sensitivity and up to 24 logic blocks
- Detection diameter up to 6 m for cross-traffic at an approximately 3 m ceiling height under manufacturer test conditions
- Temperature sensing range −20 to +60 °C; illuminance sensing range 0–500 lux
Dimensions and technical data
- Sensor dimensions: Ø84 × 42.5 mm
- Net weight: 55.4 g
- HDL Buspro operating supply: 18–30 V DC; approximately 25 mA at 24 V DC
- Indoor ceiling installation, IP20; operating temperature −5 to +45 °C
- Plastic enclosure: ABS; compatible CAT5e or HDL Buspro cable
Positioning and compatibility
Install away from air-conditioning outlets and heat sources. Detection performance depends on movement direction, mounting height and surroundings. The manufacturer’s exact-model datasheet calls this a ceiling-mounted sensor, not a surface-mounted wall sensor; confirm the fitting arrangement before ordering. Configure through compatible HDL Buspro commissioning tools.
