Ajax DualCurtainOutdoor MotionSensor

Ajax DualCurtain Outdoor — a two-zone outdoor curtain PIR sensor that detects crossing a detection plane, ideal for windows, doors, fences, and perimeter lines.

Unlike volumetric PIR detectors that cover an area, the Ajax DualCurtain creates two narrow detection curtains (beams). When someone crosses either curtain, an alarm is triggered. The bi-directional design detects motion in both directions across each beam. This makes it particularly effective for gate posts, window frames, and fence lines where you want to detect crossing a specific boundary rather than presence in a volume. Outdoor-rated with IP55 weatherproof housing. Wireless Jeweller protocol. White finish.
