Overview
The Ajax Curtain Outdoor Mini Jeweller is a small wireless curtain motion detector for guarding windows, doors, balconies, gates and shopfront glazing, outside or inside a building. Its beam is narrow, 15° wide by 100° tall, so it watches a single line of approach instead of a whole room and raises the Ajax alarm when someone crosses it. It suits homes and shops that want discreet perimeter protection on an Ajax system.
Is it right for you?
- It suits a window, balcony door, gate or shop window where a slim detector is wanted and reach up to 5 m is enough.
- Choose it where fans, air conditioners or air flows would upset a single-technology detector: the microwave sensor runs a second check.
- It is rated IP55 for -25 to 60 °C.
- It needs an Ajax hub on OS Malevich 2.34 or later and works with Hub 2, Hub 2 (4G), Hub 2 Plus and the ReX and ReX 2 range extenders.
- For longer lines or two directions from one spot, the Curtain Outdoor and DualCurtain Outdoor reach further.
Key features
- Dual technology: a passive infrared (PIR) sensor plus a 24 GHz K-band microwave sensor that filters thermal interference such as air flows and fans.
- Detection up to 5 m when mounted at 1 m, across a 15° horizontal and 100° vertical angle, at 0.3 to 2 m/s, with five sensitivity levels set in the Ajax app.
- Pet mode ignores animals up to 70 cm tall when the detector is side-mounted at 1 m with the slider set to Pet.
- Anti-masking, a tamper alarm and an accelerometer that reports if the detector is moved.
- Certified to EN 50131 Security Grade 2, environmental class IV.
- Two CR123A batteries, pre-installed, with a calculated life of up to 3 years.
- Jeweller radio up to 1,700 m in open space for alarms and events, Wings for firmware updates, and communication loss detection after 36 s.
- Slim at 145 × 32 × 43 mm and 130 g, with a supplied angle mount (145 × 44 × 54 mm fitted).
What else you need
An Ajax Hub 2, Hub 2 (4G) or Hub 2 Plus (or a ReX or ReX 2 range extender) updated to OS Malevich 2.34 or later, and the Ajax app. The SmartBracket panel and angle mount are in the box.
Installation
Mount it on the SmartBracket panel or the angle mount, side-mounted at 1 m with the slider set to Pet when pet immunity is wanted, with the beam across the opening it guards. An Ajax installer can position it and add it to the hub.
Software and licences
Sensitivity, anti-masking and accelerometer settings are managed in the Ajax app.
Before you buy
- Check your hub firmware: OS Malevich 2.34 or later is required.
- Reach is up to 5 m, so it is for single openings rather than long walls.
- Available in white.
