A wireless, bidirectional curtain-type outdoor motion detector with advanced optics and anti-tampering features. Designed to monitor narrow zones such as perimeters, windows, gates, doors, and arches, it provides focused protection while minimizing false alarms. Operates as part of the Ajax system via the Jeweller secure radio protocol. Ajax Systems+2Ajax Systems Support+2
Key Features & Capabilities
| Feature | Description |
|---|---|
| Bidirectional Curtain Detection | Two independent PIR “curtain” sensor arrays, one covering each side, allowing detection in both directions (left/right). Each side can be configured independently. Ajax Systems+1 |
| Adjustable Range & Angle | Each side has adjustable detection distance (up to ~15 m per side, totaling ~30 m if both sides active). The detector is mounted at recommended height (≈ 0.8-1.3 m) when used to guard windows/paths. Ajax Systems Support+2Ajax Systems+2 |
| Pet Immunity | If correctly installed and configured, ignores pets up to ~80 cm in height. Ajax Systems Support+1 |
| Near-Zone Detection and Beam Adjustment | Optional “near area” mode adds downward-angled detection to reduce blind spots near the detector. Physical switches/sliders allow each side’s beam direction and detection distance to be set. Horizontal viewing angle is narrow (~4.5°) for fine control over the detection strip.

| Anti-Masking & Tamper Protection | Detects if someone covers the lenses, sprays paint over them, applies tape, or tries to obscure view. Also has tamper switch for removal from mount. Ajax Systems+1 |
| Rugged Outdoor Design | Weather-resistant housing with protection class IP54; works in wide temperature range (~-25 °C to +60 °C); high humidity tolerance (up to ~95%) to suit outdoor environments. Ajax Systems+1 |
| Long-Range Wireless Communication | Uses Ajax’s Jeweller 2-way radio protocol. In open space, the communication range to the hub (or range extender) is up to ~1,700 meters. Ajax Systems Support+2Ajax Systems+2 |
| Power Efficiency & Battery Life | Powered by two pre-installed CR123A batteries. Up to ~4 years of battery life under typical usage with standard Jeweller settings (e.g. ping interval ~36 seconds). Ajax Systems Support+1 |

Use Cases & Installation Best Practices
-
Ideal for perimeter / narrow-zone protection: windows, facades, gates, archways, paths; these are narrow zones where full-coverage motion detectors may be overkill or prone to false alarms.
-
Avoid blind spots: Enable “near zone detection” especially in doorways or near windows; position correctly so the detection beams cross the intended path. Mount at recommended heights (≈ 0.8-1.3 m for doors/arches, ≈ 0.5-0.6 m when protecting windows) depending on what you’re protecting. Ajax Systems Support+1
-
Configure each side separately: Each of the two “curtains” (left/right) can have different detection distances, disable one side if not needed, direction tilt, etc., to reduce false triggers (e.g. vegetation, moving objects).
-
Use anti-masking & tamper protection: Ensure masking sensors are clear, lens not obstructed; mounting panel (SmartBracket) firmly in place.
-
Wireless signal planning: Ensure good signal strength to hub or use ReX extenders if distance or obstacles exist.
Summary
The Ajax DualCurtain Outdoor Jeweller is a specialized, high-precision outdoor curtain-style motion detector offering:
-
Bidirectional curtain coverage (left & right sides),
-
Long range (up to ~30 m combined),
-
Strong false alarm prevention (pet immunity, anti-masking),
-
Reliable wireless communication (Jeweller, up to ~1,700 m open),
-
Robust outdoor-rated housing (IP54, wide temp range).
Excellent choice where a narrow, focused detection strip is required around sensitive outdoor points or perimeters, while still maintaining high reliability and low false alarms.
