The AJAX DoorProtect Plus is a wireless combination detector that combines a magnetic contact (reed contact), a vibration detector, and a tilt sensor. It provides high-quality burglar protection for windows and doors. Furthermore, the detector is also suitable for theft protection on cabinets and similar devices. Unauthorized opening, vibration, or tilting is immediately reported to the alarm control panel. DoorProtect Plus also has a connection option for an external sensor (normally closed contact). The wireless detector is integrated into the Ajax security system via the proprietary "Jeweller" protocol. The wireless range is up to 1,200 m without obstacles.
