Motion detector Paradox DG-75/PLUS — PIR indoor movement sensor DG-75/PLUS

Paradox DG-75/PLUS is an indoor PIR motion detector designed to detect changes in body heat and report movement to compatible alarm control panels. Intended for homes, offices and small commercial spaces, the DG-75/PLUS monitors corridors, rooms and entry points to provide reliable motion sensing as part of Paradox security systems.

Advantages

The detector uses passive infrared sensing to identify human movement while minimizing false alarms caused by small animals or minor temperature fluctuations. Compact and discreet, the DG-75/PLUS is compatible with standard alarm panels from the same manufacturer and integrates into existing wired or hybrid setups. Its detection algorithm and field coverage offer consistent performance in typical indoor environments.

Suitable for

• Monitoring hallways and corridors in residential properties
• Securing individual rooms and offices in small commercial premises
• Protecting entry points such as doors and vestibules
• Use as part of a layered intrusion detection system in mixed-use buildings

Key specifications

• Sensor type: Passive infrared (PIR)
• Intended installation: Indoor use
• Detection area: Typical coverage for room and corridor monitoring (manufacturer guidelines apply)
• Environment: Designed for residential and light commercial indoor environments
• Integration: Works with compatible Paradox alarm control panels and system wiring

How to use

Install the DG-75/PLUS according to Paradox installation guidelines at a recommended mounting height and orientation to ensure optimal coverage of the monitored area. Connect the detector to the alarm control panel using the appropriate wiring or terminals, configure zone settings on the panel, and perform walk tests to verify detection coverage and sensitivity. Adjust placement or sensitivity if necessary to reduce unwanted triggers while maintaining required coverage.

Usage recommendations

For reliable operation, mount the detector away from direct heat sources, air vents and areas with rapid temperature changes. Perform periodic testing and maintenance as part of the broader security system checks and follow the manufacturer's instructions for installation and configuration to ensure compatibility and correct alarm reporting.
