Overview
The Ajax MotionProtect Plus Jeweller is a wireless indoor motion detector for rooms where a plain infrared detector would give false alarms: places with air conditioners, heaters, fireplaces or sun through large windows. Its passive infrared (PIR) sensor is double-checked by a 24 GHz K-band microwave sensor, so warm air moving through a room is not mistaken for a person. It suits living rooms, warehouses, workshops and offices on an Ajax system.
Is it right for you?
- It suits rooms and warehouses with active air conditioning, heating or fireplaces where an ordinary PIR gives nuisance alarms.
- 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).
- If the room has no heat sources, the standard MotionProtect does the same job without the microwave sensor.
Key features
- Dual technology: a PIR sensor plus a 24 GHz K-band microwave sensor that confirms movement and filters thermal interference.
- Radio frequency scanning filters interference.
- Up to 12 m range at 2.4 m mounting height, 88.5° horizontal detection angle, movement at 0.3 to 2 m/s, three sensitivity levels.
- Pet immunity for animals up to 20 kg and 50 cm tall.
- SmartDetect algorithm and temperature compensation across -10 to 40 °C.
- Tamper alarm 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, up to 1,200 m to the hub or range extender in open space.
What else you need
An Ajax hub or range extender and the Ajax app. It runs on its own battery and needs no wiring.
Installation
Mount it indoors at 2.4 m on the SmartBracket panel, lens facing across the likely path of entry. An Ajax installer can site it, add it to the hub and set 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.
- Radio range to the hub is up to 1,200 m in open space, a little less than the standard MotionProtect.
- Choose black or white; the detector is 110 × 65 × 50 mm and 96 g.
