Ajax DualCurtain Outdoor Jeweller wireless bidirectional curtain detector, 15 m per side

Overview

The Ajax DualCurtain Outdoor Jeweller is a wireless outdoor detector that watches in two directions at once. Mounted on a wall, it casts a narrow curtain of detection to the left and to the right, so one device guards the full run of a building front, a row of windows or both sides of a gate. It suits houses, shops and commercial buildings on an Ajax system that want early warning before anyone reaches a door or window.

Is it right for you?

• It suits a long wall, a line of windows or a passage where you want both directions covered from one point.
• Choose it when you need each side adjusted separately, for example a short side to a fence and a long side along the house.
• It is rated IP54 for -25 to 60 °C.
• It works with Hub 2, Hub 2 (4G), Hub 2 Plus and the ReX and ReX 2 range extenders. It does not work with the first-generation Hub, third-party panels, ocBridge Plus or uartBridge.

Key features

• Four infrared sensors giving two curtains, each with a 4.5° horizontal and 90° vertical view, so people walking along the wall are detected and the area beyond is ignored.
• Range of 4 to 15 m per side at 0.8 to 1.3 m mounting height, set separately for each side with sliders on the rear panel.
• Near zone detection adds a sector angled 40° downward from the upper sensor to cover the area right by the detector, and the viewing angle can be shifted by 3° horizontally.
• Pet immunity for animals up to 80 cm tall, with SmartDetect and ELSA software and temperature compensation against false alarms.
• Anti-masking detects obstacles up to 10 cm in front of the lenses (depending on material), painting over the lenses and taping the lenses or sides.
• Tamper alarm on removal from the surface or mounting panel, and lost connection detection from 36 s.
• Two CR123A batteries with up to 4 years of life.
• Jeweller radio up to 1,700 m to the hub or range extender in open space; 174 × 123 × 88 mm, 615 g, white.

What else you need

An Ajax hub from the compatible list and the Ajax app. It runs on its own batteries and needs no wiring.

Installation

Fit it at 0.8 to 1.3 m above ground to guard doors, arches, passages or the ground in front of windows, or 0.5 to 0.6 m above the sill when it guards windows directly. Set the range and near zone sliders for each side on the rear panel. An Ajax installer can survey the wall, position it and add it to the hub.

Software and licences

Sensitivity and anti-masking settings are managed in the Ajax app by an administrator or an Ajax PRO.

Before you buy

• Not compatible with the first-generation Hub, third-party panels, ocBridge Plus or uartBridge.
• Each side is adjusted on the rear panel, so decide the coverage before the detector is fixed.
• Available in white.
