Motion and Presence Infrared Sensor FF DR-09-IP65, IP65 Weatherproof

FF DR-09-IP65 is an infrared motion sensor with integrated presence detection designed for both indoor and outdoor installations. Using passive infrared technology, the sensor detects human movement and presence to control lighting and security systems. Its IP65-rated weatherproof housing protects the device from dust and water jets, making it suitable for exterior façades, covered entrances, carports and sheltered outdoor areas as well as indoor corridors, stairwells and utility rooms.

Advantages

The sensor combines motion and presence detection in a single unit to improve accuracy of occupancy sensing and reduce false triggers. Passive infrared operation provides reliable detection of thermal changes associated with human activity while consuming minimal power. The IP65 housing ensures resistance to dust and rain, enabling consistent performance in exposed locations. The compact design allows discreet mounting on walls and ceilings and facilitates integration with lighting control and basic security circuits.

Suitable for

• Outdoor covered entrances and porches
• Parking shelters, carports and loading zones
• Indoor corridors, stairwells and utility rooms
• Lighting control systems for energy-saving automation
• Basic perimeter or access security systems

Key specifications

• Detection technology: passive infrared (PIR) for motion and presence detection
• Environmental protection: IP65 weatherproof enclosure
• Mounting options: wall or ceiling installation suitable for protected outdoor and indoor use
• Typical applications: lighting control, occupancy detection, simple security triggering
• Operating conditions: designed for locations exposed to dust and water spray (IP65)

How to use

Install the sensor at a location that provides an unobstructed field of view of the monitored area, typically mounted 2–4 metres above the floor for optimal coverage. Connect the sensor to the lighting control or security input following local electrical regulations and wiring diagrams supplied by the system integrator. Adjust sensitivity and presence detection settings, if available, to match installation height and expected traffic patterns. Test detection zones after installation to ensure reliable activation without unwanted triggers from nearby heat sources or moving vegetation.

Usage recommendations

For reliable operation, avoid mounting the sensor directly opposite air conditioning outlets, heating units, or large windows with direct sun exposure. Regularly inspect the housing for debris buildup and clean with a soft, damp cloth; do not use solvents or high-pressure washers. When integrating into automation or security systems, configure time delays and sensitivity to balance energy savings with occupant comfort and security requirements.
