The Paradox DG85 Outdoor Quad Element PIR Detector delivers professional-grade motion detection in rugged outdoor environments. Engineered for long-lasting performance, the DG85 merges double-opposed dual-element infrared sensors with a robust weatherproof IP54-rated enclosure, making it a standout solution for perimeter protection, entrances, and high-risk external zones.

With pet immunity up to 40kg, it reliably ignores small to large pets while maintaining high detection accuracy. The DG85 is compatible with both relay and EVO bus (Combus) systems, offering flexible integration with modern Paradox security infrastructures. Its beam pattern coverage of 11m x 11m (90°) ensures wide-area monitoring, and optional lenses are available for vertical or curtain detection setups.

The detector also supports advanced features such as Auto Pulse Signal Processing (APSP) with adjustable sensitivity via trimpot and dual/single edge processing modes for refined customization. Included is a heavy-duty swivel bracket (SB85), allowing precise placement and alignment on flat surfaces, corners, or adjustable mounts.
