Ajax Dual Curtain Outdoor (8IN)

The Ajax DualCurtain Outdoor is a wireless bidirectional outdoor curtain motion detector designed to secure narrow perimeter zones such as gates, doors, windows, fences, and walkways. It uses infrared (PIR) sensors to detect moving objects with body-heat signatures and sends alarms to an Ajax hub via the secure Jeweller two-way radio protocol. The detector provides adjustable detection zones and pet immunity, allowing precise coverage with reduced false alarms in outdoor environments.

Key Features

 • Dual Curtain Detection – Two independent PIR sensors cover both left and right directions, creating a narrow detection corridor up to ~30 m total (15 m per side). 

 • Adjustable Zones – Detection distance and angle can be tuned per side for accurate protection and minimal false alarms.

 • Pet Immunity – Properly positioned, it ignores movement from animals up to ~80 cm tall.

 • Anti-Masking & Tamper Protection – Detects attempts to obstruct sensors or sabotage the device.

 • Wireless Connectivity – Communicates with Ajax hubs (Hub Plus, Hub 2, Hub 2 Plus and extenders) with up to ~1,700 m open-space range.

 • Long Battery Life – Runs for up to ~4 years on pre-installed batteries.

 • Weatherproof Design – IP54-rated for outdoor use, operating from –25°C to +60°C.

Applications

 • Perimeter Intrusion Detection – Protects fences, property edges, and driveways by detecting crossing motion.

 • Window & Door Protection – Ideal for securing entry points with precise, narrow detection zones.

 • Outdoor Passage Monitoring – Detects movement through archways, gates, and narrow corridors.

 • Pet-Friendly Environments – Reduces false alarms caused by pets in outdoor residential settings.

 • Commercial Perimeter Security – Suitable for warehouses, retail fronts, and other business sites needing exterior motion alerts.
