Overview
The Ajax MotionProtect Jeweller is a wireless indoor motion detector that triggers an Ajax alarm when someone moves through a room while the system is armed. It ignores pets up to 20 kg and 50 cm tall, covers up to 12 m and runs for years on one battery. It suits living rooms, hallways, shops and offices on an Ajax system.
Is it right for you?
- It suits an indoor room or corridor in a home, shop or office, mounted at 2.4 m with a clear view across the likely path of entry.
- Choose it for homes with cats or small dogs: pets up to 20 kg and 50 cm tall are ignored.
- It is indoor only (IP50, -10 to 40 °C). For outside areas, Ajax makes outdoor detectors.
- Rooms with strong heat sources such as air conditioners, heaters or fireplaces are better served by the MotionProtect Plus, which adds a microwave sensor.
Key features
- Passive infrared (PIR) sensor with up to 12 m range when fitted at 2.4 m, 88.5° horizontal and 80° vertical detection angles.
- Detects movement at 0.3 to 2 m/s, with three sensitivity levels set in the Ajax app.
- Pet immunity for animals up to 20 kg and 50 cm tall.
- SmartDetect software algorithm and temperature compensation to cut false alarms across -10 to 40 °C.
- Tamper alarm on removal from the wall or SmartBracket panel, and communication loss detection after 36 s.
- One CR123A battery, pre-installed, with a calculated life of up to 5 years.
- Jeweller two-way radio with encryption and frequency hopping, up to 1,700 m to the hub or range extender in open space.
What else you need
An Ajax hub or range extender and the Ajax app. Nothing else: it runs on its own battery and needs no wiring.
Installation
Mount it indoors at 2.4 m on the SmartBracket panel with the supplied installation kit, with the lens facing across the expected path of entry rather than along it. An Ajax installer can choose the position, add it to the hub and set the sensitivity.
Software and licences
Sensitivity and arming settings are managed in the Ajax app by an administrator or an Ajax PRO.
Before you buy
- Indoor use only.
- Range and pet immunity figures assume a mounting height of 2.4 m.
- Choose black or white; the detector is 110 × 65 × 50 mm.
