Motion detector Paradox DG-55/PLUS PIR

Paradox DG-55/PLUS PIR motion detector is a compact indoor sensor that monitors changes in infrared radiation to detect moving heat sources. Designed for integration with alarm panels and security systems, this passive infrared (PIR) detector provides reliable motion sensing for perimeter and room protection in homes, offices and commercial premises. The DG-55/PLUS is intended for fixed indoor installation where detection of human movement and reduction of false alarms are required.

Advantages

The detector offers stable PIR sensing with digital signal processing to distinguish genuine motion from environmental noise. Its compact design supports easy mounting and discrete placement, while sensitivity settings allow configuration to different indoor environments. The unit is compatible with standard alarm control panels and provides consistent detection across typical room layouts without requiring continuous maintenance.

Suitable for

• Indoor perimeter protection in homes and apartments
• Room and corridor monitoring in offices and commercial buildings
• Integration with alarm panels for intrusion detection
• Areas requiring discreet, wall-mounted motion sensing

Key specifications

• Detection technology: Passive infrared (PIR)
• Detection coverage: typical indoor coverage for room and perimeter sensing
• Mounting: wall-mounted installation
• Sensitivity: configurable settings to adapt to indoor environments
• Signal processing: digital processing to reduce false alarms
• Power: designed for use with standard alarm system power supplies

How to use

Mount the detector on an interior wall at a height and location that provides clear line-of-sight of the protected area, avoiding direct exposure to heating vents, windows with direct sunlight or sources of rapid temperature change. Connect the device to the alarm panel following the panel manufacturers wiring and power guidelines. Adjust sensitivity and coverage orientation according to room size and expected traffic patterns. After installation, test the detector with the alarm panel to confirm reliable detection and correct alarm reporting.

Usage recommendations

Install the unit away from air conditioning units, radiators and reflective surfaces to minimise false activations. Periodically verify alignment and sensitivity settings after changes in furniture layout or occupancy patterns to maintain optimal performance.
