Overview
The Ajax DoorProtect Plus Jeweller tells your Ajax alarm when a door or window opens, and also when someone knocks at it, forces it or tilts it. A magnetic reed switch senses opening and a built-in accelerometer senses shock and tilt, so an attempt to break in is reported before the door gives way. It suits front doors, balcony doors, windows and skylights in a home, office or shop.
Is it right for you?
- Choose it for doors and windows where you want warning of an attempted break-in, not just of an opening.
- The tilt sensor suits tilting windows and skylights, reporting when they are opened at an angle from 5 to 25 degrees.
- It is not compatible with the ocBridge Plus or uartBridge integration modules; it needs an Ajax hub.
- If opening detection alone is enough, the DoorProtect Jeweller runs longer on its battery.
Key features
- Reed switch for opening plus an accelerometer for shock and tilt.
- Three shock sensitivity levels and an option to ignore a single shock, set in the Ajax app.
- Tilt alarm threshold adjustable from 5 to 25 degrees.
- Input for a wired detector from another brand with normally closed (NC) contacts.
- Jeweller radio to the hub or range extender up to 1,200 m in open space, encrypted with frequency hopping.
- Tamper alarm when it is taken off the wall or its mounting panel.
- One CR123A battery, pre-installed, rated for up to 5 years.
- 20 mm across and 90 mm long, 29 g, in black or white.
