2GIG PIR100-345 345S Pet-Immune Motion Detector

The 2GIG PIR100-345 uses a quad-element passive infrared sensor to watch large interior spaces for movement. Its 30-by-50-foot pattern and maximum 100-degree horizontal spread make it a practical choice for living rooms, open offices, reception areas, and other spaces where a single point of detection needs broad reach.

Pet immunity can be enabled for animals weighing up to 85 pounds, helping reduce nuisance alarms when the sensor is mounted and aimed correctly. The setting is installer-adjustable rather than automatic, so placement, furniture, stairs, and areas where pets can climb all matter to reliable performance.

The detector works with compatible 2GIG 345 MHz panels and offers switchable encrypted or non-encrypted signaling. Allied positions the sensor around the property’s actual traffic patterns, then tests the finished zone so the motion coverage supports the perimeter devices instead of leaving an interior gap.
