The Ajax 1939055-81-WH1 DualCurtain Outdoor Jeweller is a wireless bidirectional outdoor curtain motion detector designed for accurate perimeter protection around homes, offices, estates, warehouses, retail sites, and commercial premises. Finished in white, it provides discreet and professional outdoor intrusion detection for protecting windows, doors, gates, archways, passages, walls, and property boundaries.
DualCurtain Outdoor features two independent narrow-angle detection systems that monitor opposite directions from a single installation point. With an adjustable detection range of up to 30 metres total, it allows installers to create precise curtain-style protection along façades, fences, entrances, and narrow outdoor zones without obstructing normal movement inside the protected area.
Using dual PIR sensors, microwave-assisted verification, and Ajax intelligent signal analysis, the detector helps reduce false alarms caused by pets, plants, thermal interference, and outdoor environmental movement. It also includes anti-masking protection, tamper detection, Jeweller two-way encrypted radio communication, and app-based configuration for professional Ajax wireless alarm installations.
